EDITORIAL

IN PURSUIT OF NET ZERO

A

s this issue goes to press, it’s “crunch time” for the Federal Government. Prime Minister Scott Morrison heads to Glasgow for the United Nations COP26 conference in November and the government is finalising its diplomatic position on climate change.

The sticking point is not so much a commitment to net zero emissions by 2050 – but whether to raise the short-term renewable energy target (RET) by 2030 (currently a reduction of 26 to 28 per cent of emissions on 2000 levels). Some parties, including the Business Council of Australia and the Australian Industry Group, are urging the RET be raised to 50 per cent.

There is some understandable concern in the government about the impact on regional constituents of swiftly moving from fossil fuels to renewable energy.

However, most MPs are also mindful of the commercial reality. Whether climate change is real or a lot of virtue signalling, the overwhelming sentiment across business and other tiers of government is that it is time to embrace renewable energy sources and invest in technologies that will replace our ageing energy infrastructure. Banks are increasingly denying loans to projects considered too energy-intensive and environmentally unfriendly. Eco-conscious shareholders are insisting their companies assess the climate risks of investment portfolios.

Communities are being more hostile to extractive activities on the perception they are “bad” for the climate. Past advocates for fossil fuels such as BHP, Fortescue and the Minerals Council of Australia have confirmed industry’s ambition to achieve net zero by 2050 and pursue new technologies.

Further, the quarrying industry globally is pledging to net zero. Boral has committed to ambitious targets for 2030 as well as net zero (page 8). Other multinationals with Australian interests – Hanson and Holcim (page 12) – have announced similar intentions. Homegrown companies Adbri and Wagners (page 10) are experimenting with less carbon-intensive

products, not only because it’s good for the environment but more cost-efficient.

OEMs are also developing electric innovations for their products to replace diesel.

The Federal Government should heed the sentiments of the quarrying industry, other industries and state counterparts of the same political persuasion (the New South Wales Government has committed to halve its emissions by 2030). Indeed, Australia has already met its existing RET obligations – thanks largely to renewable energy investments by industries and state and territory governments in the past decade - so a more ambitious, achievable target for 2030 will dispel any international doubts that Australia is not serious about tackling climate change.

The consequences of inaction are more likely to harm businesses and workers short-term than the environment long-term. The US, the UK, China and the European Union will likely impose carbon tariffs on exports from countries they perceive as “laggards”. While most quarrying companies don’t export, about 15 per cent of the industry does – including the decorated and dimension stone segment, construction sand, and cement. Do we want parts of the industry to be “penalised” because of Australia’s political position?

The Australian Government’s diplomatic stance needs to be settled. I suspect the RET to 2030 won’t dramatically lift – but a definitive position would provide certainty for business, be beneficial for exports and employment and be good for the quarrying industry.

Regardless of the outcome, the quarrying industry – globally and in Australia – will proudly lead the way in the 2020s as it works with suppliers to make operations more efficient, reduce the total costs of ownership and lower emissions in its own right.

PRESIDENT’S REPORT

END OF LOCKDOWNS GIVE US CAUSE FOR OPTIMISM IN 2022 – AND BEYOND The Institute of Quarrying

B

eing Victorian-based, it’s been a frustrating time for me as President to be mostly locked down and unable to represent the IQA nationwide. My frustration has no doubt been felt by many of our members up and down the east coast, particularly with the shutdowns and hits to construction activity in Sydney and Melbourne in recent months.

However, as I write this, there is now cause for optimism. In midOctober, New South Wales reopened for business and a few days later the ACT and Victoria announced the end of their lockdowns, effective from 22 October, as their citizens passed the 70 to 80 per cent partial vaccination target agreed upon in the national roadmap.

The transition back to “normality” may be awkward to start – as quarries seek to fill back orders in addition to their current orders – but hopefully

by Christmas we will be back into the swing of things.

Of course, we will still need to be vigilant. Just as NSW, the ACT and Victoria came into sync, Tasmania announced its own snap lockdown after the first COVID-19 outbreak in 20 months. It reinforces the importance of vaccinations which have been critical to the end of the mainland lockdowns.

If you still need to have your jabs, I urge you to organise them as soon as you can – and even if you are fully vaccinated, don’t lose sight of the safety obligations in your operations.

After the recent resets in construction, it is critical that we demonstrate to all tiers of government that the quarrying industry abides by health orders.

While there are many challenges ahead for the industry and the nation – eg the end of other states’ tight border restrictions – I think we can look forward

to 2022 with optimism. In particular, the IQA conference in Newcastle from 29 to 31 March, 2022 will enable us to reunite as an industry. As you’ll see from the conference preview on page 55, we have an inspirational, contemporary line-up of speakers for the event.

Indeed, for those of you who recently attended the WA Diversity and Inclusion Conference in Perth, we already have raised the bar for ourselves. It was a great honour for our industry to host the Hon Julie Bishop as keynote speaker.

Ms Bishop has been a champion of diversity and inclusion in the tough, male-dominated arenas of Australian and international politics. What better advocate and role model can there be for people in our industry – regardless of gender, ethnicity, culture and religion – to look up to? Ms Bishop is a tough act to follow but her stature and presence highlights our industry’s value to a whole new generation of workers.

Finally, the IQA held its Annual General Meeting on 5 October. It is pleasing to write that after a difficult year the Institute is in a sound financial position and ready to deliver on our transformation goals to 2025. It was also an opportunity to farewell Board directors Michelle Connelly, Andrew Wilson and Phil Harris, who have all been passionate supporters of the IQA. Michelle has brought some really innovative thinking to the IQA while Andrew and Phil have led their state branches in addition to their director responsibilities. I wish all of them the best in their future endeavours, both within and outside the IQA.

BORAL SETS AMBITIOUS 2030 TARGETS, COMMITS TO NET ZERO

Boral’s decarbonisation pathways to 2050 include a shift to renewable energy sources, and developing lower carbon concrete solutions.

Boral has set itself some of the most ambitious emissions reductions targets in the global construction materials industry to 2050, and joined the international Science Based Targets initiative.

Convention on Climate Change Race to Zero. The company has committed to net zero emissions by no later than 2050 and it is currently seeking validation by SBTi of its 2030 targets, which include:

The Science Based Targets initiative (SBTi) is a partnership between non-profits CDP, the United Nations Global Compact, the WWF and the World Resources Institute. The SBTi assists companies and corporates with setting science-based targets with defined programs to reduce their emissions in line with the Paris Agreement goals. There are more than 1000 businesses working with the SBTi to reduce their emissions in line with the climate science.

• A 46% reduction in “absolute” Scope 1 and 2 emissions.

Boral has joined two SBTi programs Business Ambition for 1.5oC and the United Nations Framework

‘WE ARE PROUD TO BE THE FIRST COMPANY IN THE CEMENT SECTOR TO SET SCIENCEBASED TARGETS ALIGNED WITH A 1.5°C PATHWAY FOR SCOPE 1 AND 2 EMISSIONS’

to build greener cities and create a net zero future,” Boral CEO and managing director Zlatko Todorcevski said.

ZLATKO

“Our decarbonisation pathways include shifting to renewable energy sources, and growing our proprietary lower carbon, higher performing concrete solutions.”

TODORCEVSKI BORAL CEO

• A 22% reduction in relevant Scope 3 emissions per tonne of cementitious materials, from a 2019 baseline.

In line with other construction materials and cement companies that are taking action through SBTi, these are, according to Boral, some of the most ambitious reduction targets in the global construction materials industry.

“As Australia’s largest integrated construction materials company, we have a unique opportunity to lead the way to make a meaningful contribution

“We are proud to be the first company in the cement sector to set sciencebased targets aligned with a 1.5°C pathway for Scope 1 and 2 emissions.”

Todorcevski added Boral has further redefined its strategy to become an innovator in sustainability by decarbonising its cement and other construction materials businesses and “embedding a more circular economy approach”.

Todorcevski said Boral was already investing in research and development and partnering with other bodies to bolster its sustainability and innovation efforts and access to leading technologies, as well as collaborating with customers and suppliers.

“We are supporting our customers to make more sustainable choices, including by broadening our suite of lower carbon concrete products and offering Climate Active certified net carbon neutral concrete,” he explained.

“We have a clear line of sight to deliver on our 2030 targets and beyond 2030, we are working on new and emerging technologies.”•

ADBRI EXPANDS FOOTPRINT WITH SAND QUARRIES Adbri has formed an equal joint venture with Barro Group to acquire the sand operations of Metro Quarry Group in the southeast of Melbourne.

Adbri will spend $30 million on the new joint venture, accounting for its half of the purchase to be complete during November 2021.

Barro is a substantial shareholder in Adbri, and the two companies already hold a joint venture in Adbri’s exclusive distributor of cement, Independent Cement and Lime.

The two quarries owned by Metro

Quarry November 2021

include the Lang Lang and Nyora operations which supply natural sand to regional and metropolitan Melbourne.

Adbri chief executive officer Nick Miller said this was an ideal agreement for the company as it looked to expand as reliably as possible.

“This acquisition is consistent with our strategy to extend our vertically integrated footprint and provides a compelling opportunity for Adbri to lock in a long-term secure supply of natural sand for our downstream businesses servicing the competitive Melbourne

market,” Miller said.

The competition in Victoria has ramped up in recent years as Victorian Earth Resources indicated the state had extracted a 10-year tonnage record in 2019-20.

The annual Earth Resources Sector Indicators Report found Victoria’s quarry production had increased by 25 per cent in the past six years, hitting 63 million tonnes of sand, rock and gravel for the 2020 financial year.•

WAGNERS WELCOMES BOEING TO WELLCAMP AIRPORT

THREE-YEAR STRATEGIC PLAN The Australian Constructors Association (ACA) has released its Strategic Plan to 2024, with three major focuses: culture, commercial frameworks, and capacity, capability and skills. It hopes these three pillars will facilitate a more sustainable construction industry into the future.

ACA president Cathal O’Rourke said it would be an industry wide effort to achieve the goals set out in the Plan. “We recognise that our industry needs to play its part and we are committed to doing this, but we are calling on all industry stakeholders to work together to ensure Australia benefits from a strong and progressive construction industry,” O’Rourke said.

“ACA’s purpose is to bring construction stakeholders together to influence, advocate and generate a sustainable and progressive industry.”

The Plan set out ambitious goals: • Pursue and support the highest standards of quality safety, and well-being across the industry.

• Promote and build the skills base of the industry.

• Identify and address key issues affecting industry sustainability.

ACA CEO Jon Davies said the success of these goals would also rely on government. “One of the key actions is to set and adopt a new culture standard to deliver great careers for workers and an economic boost for the nation—this will be an international first for the industry,” Davies said “The greatest challenge however is achieving consistent and widespread adoption of best practice across all the states, territories and delivery agencies.

“This is why we believe the Federal Government needs to play a more active role in incentivising and coordinating reform.”

One way in which government is aiding the adoption of these goals is through the Construction Industry Leadership Forum and Construction Industry Culture Taskforce – a joint collaborations between the ACA and governments of NSW and Victoria.•

‘WAGNERS IS FOCUSED ON DEVELOPING SUSTAINABLE SOLUTIONS FOR THE CONSTRUCTION INDUSTRY’ CAMERON COLEMAN WAGNERS CEO

The Wagner Group has endorsed a new Boeing assembly facility at Toowoomba Wellcamp Airport which presents an opportunity for the aggregates company to showcase its Earth Friendly Concrete and Composite Fibre Technologies.

The Boeing facility is located within the Wellcamp Aerospace and Defence Precinct in Queensland, neighbouring Wagners’ Composite Fibre Technologies manufacturing facility.

The new addition will be used to assemble the Boeing Airpower Teaming System and is expected to create around 300 jobs under construction.

Wagners chief executive officer Cameron Coleman said the company has continued to improve its brand awareness in sustainable construction.

“Wagners are well known for being suppliers of constructions materials and services, but a large part of our business is focused on developing and delivering innovative and environmentally sustainable solutions for the construction industry,” Coleman said.

These solutions include Earth

An aircraft on the runway apron at the Wagner Group’s Wellcamp Airport.

Friendly Concrete which substantially reduces the embodied carbon compared to ordinary concrete, saving 250 kilograms of CO2 per cubic metre.

“To have the ability now to be able to showcase these materials in projects like the Boeing facility right in our back yard is something we are extremely proud to support,” Coleman said.

“We look forward to exploring opportunities that this project may provide for Wagners and our region generally. This facility is going to provide significant benefit for our community, and we look forward to welcoming Boeing to Toowoomba.” •

FINAL SALE RELIEVES BORAL OF BUILDING PRODUCTS BUSINESSES Boral has completed its pivot away from building products with the sale of its roofing and masonry business to private equity company Lutum.

As Boral continues to create a stronger focus on construction materials, the sale ensured the business was off to a good home, according to a Boral spokesperson.

“Lutum is a private Australian company whose founders have collectively over 60 years’ experience in the building, roofing, and construction industry,” the spokesperson told Quarry.

The price of the business was not disclosed due to its negligible size but Boral will keep some relevant infrastructure, including ownership of land at Emu Plains where the New

South Wales concrete roofing plant currently operates.

Boral had owned the business since the 1970s and acquired the Wyee clay tile business from Montoro in the early 1990s.

The business was originally announced as up for sale in Boral’s full year results, released in late August 2021.

Also discussed in the results was the previously announced successful divestment of several other businesses, including Midland Brick, Meridian Brick, North America Building Products and Fly Ash businesses, Boral Australia’s softwood and hardwood timber business, and Boral’s 50 per cent share in USG Boral.•

REGULATOR APPROVES REGIONAL GROWTH FOR VICTORIA The Victorian Resources Regulator has approved a major new sand quarry for Latrobe Valley Sands in the state’s east, adding to a growing list of approvals since July 1.

The in-principal approval will still require a planning permit and a phase of public consultation before Latrobe can access the 100 million tonne resource outside of Traralgon.

Regulator executive director Anthony Hurst said the approval was part of a wider effort to boost infrastructure growth in the region.

“Earth Resources Regulation is continuing to assess a high number of applications to lift production at quarries in Gippsland, across regional Victoria and around Melbourne,” Hurst said.

To cater to the record growth levels, Hurst said compliance checks would also ramp up.

“Our inspectors will continue to monitor quarry activities to ensure compliance and protect public safety and local environments,” he said.

Since July 1, 2021, six quarry work authorities have been approved to combine for more than 6.4 million tonnes of construction materials.

In August, the annual Earth Resources Sector Indicators Report found Victoria’s quarry production had increased by 25 per cent since 2015, hitting 63 million tonnes of sand, rock and gravel for the 2020 financial year. •

MAAS GROUP GROWS INTO QUEENSLAND’S ‘ENGINE ROOM’ ‘THE QUARRY ITSELF IS SITUATED ON A RAIL SIDING AND HAS FOR MANY YEARS BEEN A MAJOR CONTRIBUTOR TO RAIL MAINTENANCE IN THE REGION, PROVIDING RAIL BALLAST DIRECTLY ONTO TRAIN WAGONS’ RICHARD TOMKINS REGIONAL GROUP AUSTRALIA

Maas Group Holdings (MGH) will acquire a hard rock quarry in Gladstone, Queensland, allowing its subsidiary Regional Group Australia (RGA) to grow its footprint in the state.

The Gladstone site 525km north of Brisbane has been owned and operated by Earth Commodities for more than 30 years.

RGA general manager Richard Tomkins told Quarry this was a strategic achievement for the company. “Gladstone is an industrial engine room of Queensland with a naturally deep harbour that offers tremendous growth opportunities into the future,” Tomkins said. “The quarry itself is situated on a rail siding and has for many years been a major contributor to rail maintenance in the region, providing rail ballast directly onto train wagons.”

The site is approved to extract one million tonnes per year, which Earth Commodities supplied for a range of products such as asphalt, concrete, road sealant and pavers.

Tomkins said the site “has large, consented reserves remaining which enables it to supply high quality construction material to all market

12

segments in the region such as road, rail, concrete and marine infrastructure projects”.

He added the business is developing a “hub and spoke” model across Central Queensland. The Gladstone acquisition comes less than six months after MGH acquired Amcor Quarries and Concrete, Amcor Excavations and Willow Tree Gravels more than $27 million.

These businesses are located around 110km northwest of Gladstone and have allowed MGH to add up to a million more tonnes of construction materials per year to its books and 112 employees to the Maas workforce. •

LAFARGEHOLCIM ACHIEVES US FIRST WITH SUSTAINABLE PLANT LafargeHolcim has converted a cement plant in Texas, USA, to only produce decarbonised cement, furthering its efforts to develop sustainable construction materials.

OneCem is a blended cement product which uses up to 15 per cent finely ground limestone per tonne, reducing the amount of carbon intensive clinker used.

ERR is assessing numerous applications to lift quarry production across Victoria.

The Gladstone hard rock quarry purchased by Maas Group subsidiary Regional Group Australia.

LafargeHolcim US cement chief executive officer Toufic Tabbara said solutions to decarbonise were not far-fetched any more. “LafargeHolcim has gone on record with our net zero commitment. While we’re actively investing in technology and innovations to help us get there, it’s crucial we take immediate steps to reduce our carbon footprint.

“Transitioning the operational focus at our Holcim Midlothian plant (Texas) to OneCem reflects our confidence in this product and in the growing customer demand for solutions that help them achieve their own sustainability goals.”

OneCem is part of the company’s Envirocore Cements which use supplementary cementitious materials. It offers the same level of performance as standard cements but reduces carbon emissions by five to 10 per cent per tonne of cement.

The Midlothian plant produces 1.8 million tonnes of cement per year and a total conversion to OneCem will reduce the plant’s annual carbon emissions by more than 31,000 tonnes. •

STEM STUDENTS MOVE VOLVO HAULER WITH BRAIN POWER A Volvo A60H articulated hauler has been towed using only LEGO Technic elements, in a quirky challenge set up by Volvo Construction Equipment (CE) and LEGO Group.

The challenge was set in early 2021 for 35 young science, technology, engineering and mathematics (STEM) students and solved in three months.

The students – who had never met in person – devised a system using 728,168 LEGO Technic pieces connected under an array of steel plates to create 1920 motors.

The 43-tonne A60H was loaded with an extra 45 tonnes of rocks to ensure the challenge to move it 50 metres was particularly difficult.

Volvo CE engineer Frida Jönsson said the challenge was multifaceted and the students were more than up to it.

“The students showed incredible resilience and tenacity. In total they spent more than 2000 hours of their own time to come up with a hardfought solution that could create a pulling force of 10,000 Newtons in order to get the hauler moving,” Jönsson said.

“Despite their plans very literally turning to ashes on the first attempt (when a fire broke out forcing them back to the drawing board) the teams showed that with collaboration, teamwork and a good dose of creativity, you can always find a way to succeed.”•

ORICA 4D CONTINUES TO CHANGE THE FACE OF BLAST TECHNOLOGY ‘BY COMBINING OUR RANGE OF ADVANCED DIGITAL, FORMULATION CHEMISTRY AND EXPLOSIVES DELIVERY TECHNOLOGIES WITH OUR TECHNICAL EXPERTISE, WE CAN OFFER THIS BREAKTHROUGH SOLUTION THAT WILL UNLOCK GREATER VALUE FOR OUR CUSTOMERS ACROSS THEIR OPERATIONS’ ANGUS MELBOURNE ORICA

Orica has unveiled 4D, a bulk explosives technology designed to produce even more desirable blast outcomes with a different kind of approach.

4D is built for anticipation, functionality and proactivity, delivering improvements in fragmentation, bench productivity, and reducing overall drill and blast costs.

Suitable for pumped and augered loading methods across dry, wet and dewatered hole conditions, 4D combines emulsion blended with ammonium nitrate porous prills.

This results in greater bench productivity by Orica’s fleet of 4D-enabled Mobile Manufacturing Units (MMU), without the need to change raw materials in the MMU. 4D enables a broader range of applications, promising up to 23 per cent more relative bulk strength for hard rock applications and up to 43 per cent reduction in soft rock.

Orica chief technology officer Angus Melbourne said 4D is the “convergence of our new technologies and solutions, allowing our customers to think differently, mine more efficiently and operate more precisely”.

Israeli archaeologists have discovered a 2000-year-old quarry site in Jerusalem which could have been used to source the materials for the Second Temple, the Jewish holy site.

The site was located around four kilometres north-west of the Temple Mount, where the Second Temple would have sat from 515 BCE to 70 CE.

Quarry November 2021

“By combining our range of advanced digital, formulation chemistry and explosives delivery technologies with our technical expertise, we are able to offer this breakthrough solution that will unlock greater value for our customers across their operations, Melbourne said.”

Orica vice president for blasting technology Adam Mooney said 4D marks the next generation of bulk explosives technology.

“Traditionally blast designs are driven by powder factor,” he said.

“4D enables us to consider another dimension – the application of energy in real time matched to the rock strength of the blast pattern as well as the desired blast outcomes.This is a really powerful technology that will allow customers to manage their drill and blast operations, and achieve improved blast outcomes.”•

JERUSALEM QUARRY TURNS BACK BIBLICAL CLOCK

The site was excavated as a salvage dig in preparation for the construction of new buildings in the neighbourhood of Har Hotzvim – which loosely translates to “quarrymen’s hill’, or “stonecutter’s mountain”.

A 43-tonne Volvo A60H has been towed 50m on a rolling motorised grid powered

by LEGO Technic elements.

The convergence of Orica’s technologies powering the new 4D bulk system.

The uncovered area of the quarry measures about 600m2 but the archaeologists believe the entire site

could be two to three times larger.

The building blocks extracted from the site some 2000 years ago measured about 1.5 metres by 2m and clearly displayed several quarrying processes.

On behalf of the Israel Antiquities Authority, the excavation director Moran Hagbi told The Times of Israel that he believed the findings could be beneficial to current day processes. “[The quarry] presents a golden opportunity; because some of the stones were left in situ in this way, we can copy ancient technologies and experiment with them in order to recreate the processes by which the building stones were quarried,” Hagbi said.•

MOBILE VSI PROMISES

RELIABILITY FOR QUEENSLAND QUARRY At an operation 400km north of Brisbane, Booyal Quarries adds value for its customers thanks to the reliability of Precisionscreen’s latest innovation in VSI crushing.

B

ooyal Quarries has laid many a foundation upon its history in quarrying and construction materials.

The independent, family-owned business has supplied councils, road contractors and all-comers with high quality Main Roadscertified gravel, road bases, aggregates and drainage rock for a lifetime.

That is, the lifetime of Booyal Quarries owner Bruce Evans, who began in the quarry game at 14 years of age, over five decades ago.

Evans told Quarry that Precisionscreen had provided plenty of reliable machinery for his business over the years.

Most recently, this included the Trackcrush PV380 VSI (vertical shaft impact) crusher for extra fines at the heart of Booyal Quarry.

“We were trying to produce fines for roadbase. Our rock is a very fine grain and it’s very hard so you can have trouble getting fines out of it,” Evans said.

“Our plant produces both 2.1 and 2.3 spec at the same time, so the PV380 was used for the 2.3 and it was making the grade just fine.”

The PV380 provided Booyal with some extra reliability on top of its current machinery, as a growing Queensland infrastructure sector demands more out of its suppliers.

18

Quarry November 2021

Booyal has tried and tested a range of equipment from a range of brands, and recognised Precisionscreen as a suitable back-up when its primary machines went sour.

“I looked at the PV380 for a back-up machine because with dust and electrics on-site we had some trouble with our other plant,” Evans said.

“I thought if we’ve got a machine we can use while we’re fixing other ones, we can keep the plant going.”

Evans’ other purpose for the machine was to crush at the face of the quarry rather than loading and hauling out to stockpile.

This ability is enabled by the machine’s tracked and mobile nature, as well as its inbuilt spirit level.

Evans said both were major drawcards in the selection of the PV380.

“What I like about it is the self-levelling features. If you’re working on an uneven surface, you can walk it into an area and level it up,” Evans said.

“This meant we didn’t have to spend as much time preparing the base for it. You could have it a little bit off and just use the little spirit level to bring it even.

“It’s just little things like that which they’ve thought of which some other manufacturers don’t offer.”

DIRECT DRIVE SYSTEM Also rather unique to this machine in today’s crushing market is a direct drive system, owing to Precisionscreen’s mantra of ‘simplicity without compromise’.

Precisionscreen general manager Paul Kerr explained the purpose behind the design of the PV380.

“Similar to all of our machines, the PV380 is designed to be easy to service,” Kerr said.

“It’s based on a direct drive system which makes for less componentry. It has a hydrostatic drive directed to the VSI chamber, making it simple.

“The overall design has been done to meet stringent Australian standards which leads to a machine designed for robust markets like the Australian environment.”

And a harsh Australian environment calls for tough and trusty crushing power, which is well afforded by the PV380.

Building on the previous model – the PV350 – this model welcomes a Caterpillar C18 engine with 600kW (or 800 horsepower).

Evans said his unit was easily managing 300 tonnes of material per hour and hardly broke a sweat.

“There are no belts to burn off like some others might have. Plus, you’ve got all the horsepower you really need,” he said.

“At this rate, too, it’s still only using 50 to

60 litres of fuel per hour, compared to others these days which push past 100 litres per hour.”

These figures are all assured by the PV380’s new PLC (programmable logic controller) and on-board computer for remote or on-site monitoring.

These additions to the machine will report key metrics such as engine, oil, and lubricant temperatures, emergency stops, and belt speeds and slippages.

HOMEGROWN PARTS, COMPONENTS Kerr said integrating new technologies into traditionally standard machines helped owners and technicians to understand what’s working and what needs further development.

“These offerings mainly assist with remote service and support while providing a better understanding of the machines for clients and our team,” Kerr said.

“This information comes through on an app which involves a SIM card and remote assistance from the Precisionscreen team.

“We’re working into this space to enable our clients better remote assistance while they’re stuck over state borders during COVID restrictions, and we expect this will continue to be a trend into the future.”

Another trend Kerr expects to continue until at least March 2022 is a significantly impaired global supply chain.

This has led companies like Precisionscreen to stock up on six months’ worth of parts rather than the usual two or three. And when every company is thinking in a similar vein, delays will inevitably occur.

To mitigate this, Precisionscreen already manufactures all its equipment in Australia,

Booyal Quarry, located in Queensland’s Bundaberg region, runs on mobile crushing plant and equipment.

removing shipping times for entire machines.

But Kerr said the company was taking things one step further to supply its partners as soon as possible.

“We are redesigning our machines to take commonly available parts in Australia into consideration,” he said.

“So, where we’ve had parts imported, we’re making a conscious effort through our supply chain in the redevelopment of our machines to select items that we think will be more readily available for our machines.”

This means almost everything, down to the wiring for the on-board computer will be sourced locally, subsequently enhancing Precisionscreen’s ability to support the product.

“For a lot of people, the PLC is a fairly complicated item that can be hard to troubleshoot as they’re usually built overseas,” Kerr said.

“But at Precisionscreen, where the PLCs are built in our own facility, we can troubleshoot it, we can source componentry and we can get our team out to site for any teething problems

a client might have.”

Such is the support afforded by Precisionscreen, Evans attested to the team’s ability to solve any issues he had with the PV380 – or any of his other units from the Queensland manufacturer.

“We had no problem asking the Precisionscreen team to come out for backup service,” Evans said.

“For any teething problems we’ve ever had they were up here talking it all out, even on weekends, so we weren’t ever waiting around for them.”

FUTURE INVESTMENT Of course, one should expect nothing less when opting for an investment like the PV380.

Which is exactly what Kerr saw in the PV380 for Australian quarrying businesses – an investment.

He said there is good reason to take advantage of the market conditions as they are, so long as the investment is one that is well supported and Australian-made.

“Accounting for expenses, labour, parts and componentry, running a business is becoming increasingly hard with supply issues,” he said.

“So, if you can afford the capitalisation, which I think most can with historically low interest rates, that should be a big driver.

“The government’s structure is leaning towards cheap borrowing in a lot of ways so there’s a big advantage in buying bigger, more productive, newer machines which guarantee reliability for an ongoing period.

“It’s more of a safe bet buying a new machine, obviously, and that’s a similar benefit to buying Australian-made equipment.

“If it’s made in Australia, it’s easier to support in Australia and current supply issues are affecting everyone these days.”• For more information about the Precisionscreen Trackcrush PV380 VSI, visit precisionscreen.com.au

HIGH POWER PUGMILL SEES RAPID RESULTS FOR CIVIL CONTRACTOR

R

apidmix allows for on-demand batching in a range of applications, enabling quarrying operations to broaden their horizons with a single investment.

Lincom Group is the exclusive distributor to 10 different brands in crushing, screening and materials handling. The family-owned business was founded in 1994 with its head office in Queensland and now offers a distribution network spanning Australia, New Zealand, Papua New Guinea and the Pacific Islands.

One brand under the Lincom umbrella is Rapid, which specialises in mobile concrete batching plant/pugmills and has grown to cement its name in the Australian landscape for more than 10 years.

Lincom recently deployed a Rapidmix 400CW (continuous weigh) to a civil contractor in New South Wales and the business quickly found it had gained more value than it expected.

The business set up the 400CW in its own quarry to produce stabilised materials such as roadbase for local and main roads in their locality.

Lincom general sales manager Darren Smith (well known as Barney) said the customer’s intended use was just the beginning of their Rapidmix ownership.

“They were cautious of the Rapidmix for a period of time but now they’ve put it to work they understand there’s a lot of potential for further work with it including soil stabilisation and moisture addition,” Smith told Quarry.

“There’s a lot of uncharted stuff they haven’t dabbled into yet.”

Outside of this contractor, the 400CW has been used on a Brisbane Airport expansion, Cairns Airport, and major works to the Pacific, Hume, and Bruce highways.

The 400CW builds upon the previous Rapidmix models with greater accuracy, a timed gob hopper and an on-board metrics system for easier reporting.

“There used to be the Rapidmix 400 Volumetric which measured speed over time and volume, whereas the 400CW continuously weighs the material in real time,” Smith said.

“This provides more accuracy, plus you can see a percentage value of all of the materials being passed through the pugmill itself – that’s the feed material, the binder and the water.”

20

Quarry November 2021

The Rapidmix 400CW has been designed at ground level for easy access.

With the 400CW, operators aren’t only assured of accuracy, but volume and speed as well.

Having a silo capacity of 40 tonnes at 1.4t/ m3, the mill can churn out material at a rate of up to 400 tonnes per hour depending on powder percentage, feed size and type.

A mix of three to four per cent binder for example, would allow the 400CW to run at 350 tonnes per hour.

After running through the machine’s 3.6m pugmill with 72 paddles at 110 revolutions per minute (rpm), the material is fed up the 1200mm conveyor belt into the gob hopper to load trucks, Smith explained.

“The other feature with this mill is the timed gob hopper. This is part of the RMS spec that you must have a timed gob hopper for loading trucks rather than a loader, as this will minimise segregation” he said.

“With every feature considered by the Rapid team, customers can be confident that what goes into the back of the truck is 100 per cent what is intended.

“Customers are looking for accuracy in the binder because if you don’t have that accuracy, it can cost you a lot of money.”

The 400CW can get within 100kg of loading a truck to the correct weight. Of course, this is particularly impressive when loading a

25-tonne truck, for example.

This accuracy is certified by a user-friendly touchscreen on the 400CW with a simple calibration process for extra assurance.

The machine can be zeroed every day and can be set up on site in less than four hours before hooking up a water supply and churning out the desired material.

Aside from its various features, Smith said a big drawcard was in the Rapidmix 400CW’s easy maintenance requirements.

“A big feature of the design is the cleaning of the machine. You can clean everything from ground level as the top and sides of the pugmill drop down for easy access,” he said.

Just as the Rapidmix has its operators considered, so too does Lincom.

Smith said he and his team are always keen to get on site with customers for the commissioning of products like the 400CW. “It generally takes around a week from first inquiry to final commissioning and the customer can get to work satisfying their own clients,” Smith said.

“If we can’t get out to site in a couple of hours, we can log into the machine remotely and walk the customer through any trouble shooting they might need.”• For more information on the Rapidmix 400CW, visit the Lincom Group website: lincom.com.au

VERSATILITY, RELIABILITY

UNDERPINS VIBRATORY SCREEN RANGE With so many products and brands available in the crushing and screening segment globally, it can be daunting for quarrying producers to make an informed choice. Ed Sauser explains why an OEM’s vibratory product range can provide a significant point of difference.

I

n recent months, Quarry has reported how original equipment manufacturer (OEM) Superior Industries, based in Minnesota, USA, is seeking to provide quarries globally with innovation and product differentiation in its products. This is particularly important at a time of major disruption in the Australian and global supply chains, in which consolidation of OEMs has led to a narrowing for quarry producers in the quality, quantity, and choice of plant, equipment and support services.

Superior Industries engineers, manufactures and supplies bulk crushing, screening, washing and conveying systems plus all related parts and services for the quarrying and mining industries. The 50-year-old multinational began life as a fabrication shop and over time developed a solid business in the manufacturing and distribution of conveying systems and portable plants.

22

Quarry November 2021

Since 2015, Superior has diversified into the crushing, screening and washing market, offering some popular product lines to US producers such as the high speed Patriot cone crusher and the triple-shaft Guardian horizontal screen.

Most importantly, Superior Industries can customise its products to fit static, modular and mobile applications. This fits the OEM’s mission to provide its customers, based off their input and feedback, with a “one-stop shop” of viable plant and equipment from the quarry face to the load-out.

In Australia, Superior’s distributors include Tricon Equipment (east coast) and 888 Crushing & Screening Equipment (west coast). Some of Superior’s renowned washing plant and equipment has already been installed in some east coast quarries.

Ed Sauser is Superior Industries’ vibratory

product manager. Although he has only been involved with the company since late 2020, he has worked across the extractive industries for 33 years. As a design engineer for a major OEM, Sauser oversaw the production of aggregate processing equipment from conveyors to vibrating screens to portable plants over three decades. In that period, he was a product manager for 12 years, being responsible for his employer’s overall aggregate processing lines. In December 2020, he joined Superior Industries.

“I’m responsible for the product lines for Superior’s vibratory incline screens, horizontal screens and vibrating feeders,” Sauser said of his role at Superior. “The role covers all aspects of the products, from the building of the equipment to procurement of the parts, the servicing, the product line development, and the training of the sales team people

on the product lines. One of the goals of the company is to make those products the best in class, not only in the product itself but in the production and the support of that equipment, so I am involved in all aspects of it.”

IMPROVING UPTIME A strong perception of quarrying plant and equipment, particularly of crushers and screens, is that it has not evolved dramatically in the past century and there is little visibility of difference between brands. Sauser said it’s a common sentiment of customers that screens work off “the same DNA” but he added there are subtle differences “they don’t see when you get into the guts of the machines and the production processes”.

In particular, he argued that Superior prides itself on its versatility, including the capacity to build plant and equipment for multiple applications in a quarrying environment.

“What’s unique about Superior is that we package more screens in washing applications than any other major manufacturer,” Sauser explained. “That’s mainly because of our expertise in the packaging of our washing and screening equipment. We place a lot of our equipment into washing-type applications, and in doing

so we realise there are ways we can improve our processes. We manufacture enough of our own turnkey systems to see how we can improve. When constructing vibrating mechanisms to keep out water and dirt, we’ve developed what we consider best in class plant.”

He added that the upshot of product improvement is that “we maximise the uptime. The screen is only one aspect of the process but it is a very important part.

Crushers and processing equipment tend to be more expensive than screens but having downtime on a screen potentially takes the whole system down.

“Our focus is to make our screens the most reliable products they can be. The best way we can do that is through sealed construction, to protect the bearings and gears to get the longest life out of them. We can mechanically seal joints in our equipment that other OEMs don’t do,” Sauser added.

“We do shot blasting of the metal before

GOING MOBILE

we do the welding for a cleaner product. I don’t see anyone in the industry who does sealing systems better than we do and that’s derived from our experience in washing equipment. We’ve paid attention to how all the components are assembled to handle those applications. The more durable our products are, the greater the uptime and the efficiencies.”

VIBRATORY OFFERINGS Superior Industries offers four key products in its vibratory range. The high energy Anthem inclined screen, available in twin- or tripledeck configurations, operates at angles of 15 to 20 degrees to move continuous feeds of material up to 406mm in a circular motion down the decks and through the media. It can be used in modes from heavy scalping to fine finishes and is most commonly employed in stationary applications.

The Guardian horizontal screen, available in two-, three- or four-deck configurations, operates at a flat angle from zero to 10 degrees, with a series of vibratory shafts that push material the length of the screen. Larger material (up to 254mm) is confined to the top deck while smaller rocks and stones (from 150mm down to 3mm) pass through four layers of uniquely sized screen media. The four-deck configuration offers a five-product split (four end products and one oversize).

Horizontal screens are typically used in portable or mobile applications.

Sauser said of the Anthem inclined and the Guardian horizontal machines that they reflect a “higher degree” of low angle, horizontal and low slope screens.

“Elliptical motion is becoming more popular,” he elaborated. “Screen design in the past 20 years has moved a lot in that direction. Elliptical motion is more efficient, in terms of separating materials, as it goes through the upstroke, the media approaches the material at a perpendicular angle, so it has the highest probability of aligning similar particles. That’s why manufacturers have promoted that. We’re seeing more interest in elliptical screens because of the higher efficiency. Linear strokes are also popular in the crushing space for higher efficiency.”

Sauser said the Guardian screen had been the most popular of Superior’s vibratory lines, largely because it was the first vibratory machine that was put to the market. “The incline screen line tends to be more popular in the replacement screen business. They tend to be duplicates of the previous

machine. When you have a customer already attached to a product line it’s hard to persuade them to change to a different one.”

The Intrepid vibrating grizzly feeder (VGF) separates and removes undersized materials while providing a continuous feed to the crushing plant. It comprises of a pan section at one end of the machine that is followed by a series of evenly spaced bars at the grizzly end. Material fed to the pan is conveyed to the grizzly section by vibrations that move finer particles to the bottom of the load while discharging the oversized rocks to the crusher. It can be employed in a stationary application or mounted to a wheeled chassis.

The fourth product in Superior Industries’ vibratory offering is the dewatering screen, which is available in portable or skid-mounted structures. It has a total screening area of nearly 13m2 and can process material at a maximum 360 tonnes per hour (tph).

Superior’s dewatering screen is unique for featuring urethane screen sidewalls to expose sand to more screening action and remove moisture content (to as low as eight per cent). Combined with a higher g-force, the dewatering screen also has deeper sand depths to physically express more water and to allow for greater tonnages.

“The dewatering screen produces a drier product than a fine material washer, which is a screw-type product,” Sauser said. “It also uses a higher frequency. It’s actually a component within our Aggredry Washer and Alliance Low Water Washer offerings – it’s the dewatering device at the end of the

washing process – but it can be employed as part of a regular screening circuit for finer materials. We use our sideliners to decrease the watering area. This gives us the ability to remove more water with more area.”

Sauser reiterated that the advantage of the vibratory range is that it is not limited to any one application and can be adapted accordingly to customer feedback. This means all four of the machines can be adapted to suit static, semi-portable and mobile applications – with certain caveats.

“The large static plants have the engineering and construction management expertise to design systems for 2000 tph,” Sauser explained. “Our portable line can manage up to 600 tonnes per hour. It’s a package that you can put on wheels but it’s a question of weight, there’s a breakpoint there. Pre-engineered, semi-static equipment is popular. Those would typically be under 600 tph. Some of those are creeping up in the 600 tph range because we’re putting more components on the semi-static equipment. In those applications, where the cost per tonne is looked at very closely, and electric power plants are desirable, it’s just a matter of how big a system you want.”

Further, it is entirely possible to, in Sauser’s words, “mix and match the products”. He said the low profile Guardian triple-shaft machines are “very prevalent in our washing applications because of the low slope, to avoid the producer washing product down the media. More and more producers in the sand washing segment are using the

Guardian. It has been very popular in the water applications”.

Sauser said that the bulk of Superior’s plant and equipment, not just its own screens, is powered mostly by electrical power units, with a handful of products that are solely dieselpowered and others that are a hybrid of both.

AUTOMATION, FUTURE INNOVATIONS The vibratory range is, like most of Superior’s products, assisted by modern automation and monitoring features. Sauser anticipates that there will be further advances in automation and sensory/monitoring devices in the next decade and beyond.

“As far as controls go, I would say that Superior is on a par with the other OEMs,” Sauser said. “There will be changes coming in self-monitoring/diagnosis equipment in the industry but it’s not there yet. We currently have methods to examine the motion of a screen and consider ways to make the equipment smarter and monitor itself and be able to tell the operator what it needs. I can see advances moving in that direction.

“To an extent, we’re already doing that on the cone crushing lines, where the equipment is made smarter to monitor itself. It’s not quite the same, though, there’s not the same components on screens like there are on cone crushers.”

Nonetheless, Sauser expects such technology, particularly as part of the Internet of Things, to be beneficial for plant operators.

“I expect products to be expecting less oversight and maintenance, and there will be a strong ability for self-monitoring. Uptime is also important because it helps the workforce

26

Quarry November 2021

to do its job better. Self-monitoring equipment will help the operators to achieve what is needed in quicker time and at less expense.

“The challenge, though, is the development of it,” he qualified. “It’s about being able to develop the communication protocols. The Internet of Things hasn’t been talked about for a while but it’s not dead, there are things going on in the background that people aren’t aware of and you’ll see those things eventually in the marketplace.”

In the meantime, Sauser said Superior Industries remains committed to improving the uptime and reliability of its vibratory and other products to deliver “best in class”. The key to that lies in the company assessing industry producers’ input and feedback.

“To be successful in the aggregates machinery business, the product support is key and you have to have people out there supporting the equipment. We take a lot of input about products from our dealers and

our distributors. It’s driven by the needs of the customer base that’s fed through the distribution channels.

“Superior is a unique company that acts very quickly and is very dynamic in its responses to problems and solutions,” Sauser concluded. “Our team works very well and has a goal to be ‘best in class’, it’s not just a slogan. Further, our construction management team has a fantastic record in putting systems together. Quarries that want to work with us will realise that we are a company that offers a broad range of quality products and that we are dedicated to supporting those products. People will enjoy working with us, given the opportunity.”

CRUSHING PINNACLE

GROWS FAVOUR AROUND AUSTRALIA The Metso Lokotrack LT120 tracked jaw crusher has been a mainstay of the Australian mobile crushing market. Tutt Bryant Equipment principal Paul Doran explains why.

T

utt Bryant Equipment unleashed the Metso Lokotrack LT120 mobile jaw crusher some years ago and has since grown its national fleet to 24 units in Australia.

The authorised Metso Outotec distributor turns to this machine when it knows nothing else will match up with the demands of a crushing job. The LT120 manages oversize with ease and turns multi-operator jobs into the one-man variety.

Paul Doran, Tutt Bryant Equipment’s business development manager for Metso products, said the Nordberg C120 jaw crusher was at the heart of the LT120’s reputation.

“The C120 jaw crusher is internationally renowned,” Doran told Quarry. “Metso jaw crushers are rated to 500 megapascals (MPa) so these things will handle almost anything you can throw into them – they are a weapon.

“We have a number of case studies from customers all around the country who have done amazing volumes and have a good, long history of high serviceability and production.”

Tutt Bryant offers a five-year, 10,000-hour warranty on the Lokotrack machines which is considerable in the context of their 10,000- to 20,000-hour-plus lifetime.

The LT120’s raw power is enabled by a range of design features that Metso has implemented based on customer feedback.

“They have a very aggressive nip angle, and a high inertia flywheel to generate a lot of

power to the crushing process,” Doran said.

“Metso crushers are also pinned and bolted together, allowing for greater flexibility and better resistance to cracking compared to a welded machine.

“The machine’s portability is another drawcard. It weighs between 60 and 68 tonnes, but you can get it on a float and drive it off at the other end to operate soon after.”

Once set up, operators will enjoy the convenience of a conveyor magnet for steel or similar material which finds its way among the rock. Tutt Bryant equips a large hammer and boom to the LT120 as standard, to mitigate the issue of oversize material in the feed hopper.

“This pairs great with the rest of the machine as usually when you find some oversize material in your feed hopper, you’d have to alert an excavator with a hammer on it to make its way over to the crusher,” Doran explained.

“But with the hammer and boom attachment, the crusher operator – sitting in the comfort of their cab – can use a remote to get to work on the oversize themselves. Unless you have subsequent crushers involved where it’s good to have someone else taking a second look at the material, it almost becomes a one-man job with the LT120.”

SAFER, SMOOTHER TECH Metso Outotec has also made a name for itself in the technology space with Metso

IC and Metso ICr both enabling safer and smoother operation.The IC is the in-built operating system for crusher automation, monitoring and control of key parameters; the ICr is the remote-controlled sibling.

“The operator can then wirelessly manage some of the basic parameters on the LT120 via Bluetooth without leaving the cabin of their machine,” Doran said. “This is totally unique to Metso and Tutt Bryant brings this is in as part of our standard offering.”

“The operator can start and stop the feeder and widen or narrow the jaw’s closed side setting, all from the comfort and safety of their seat.”

Operators can not only control the LT120 but monitor its performance and perform fault-finding duties.

Higher up the company ladder, Metso Metrics allows machine owners to monitor a machine’s performance from anywhere in the world via the internet.

This includes performance metrics such as fuel consumption, uptime, location, service requirements, log maintenance tasks and which alarms have come up recently.

As an added measure, Metso has designed the LT120 with a bypass arrangement under the feeder, sending all the fine materials directly to the chosen conveyor – product or side – if the operator so chooses.

“Alternatively, you can send certain size

SPECS – METSO LOKOTRACK LT120

particles to the side conveyor and the oversize particles to the product conveyor,” Doran said.

“This gives you operational flexibility for a variety of situations which quarry businesses come across every day around Australia.”

Metso has created a powerful and precise machine which satisfies right down to the finer details.

Doran said the LT120 even comes with its own Noise Map how best to position the machine to mitigate noise disturbance.

“We offer noise maps with our Lokotracks which allow us to show the customer where the most noise is being distributed,” he said.

“They can then orientate the crusher on-site to minimise the noise to the neighbours. This is extremely important in residential areas where noise restrictions can come into play.” • For more information about the LT120 and the Lokotrack mobile range, visit the Tutt Bryant Equipment website: tuttbryant.com.au/tutt-bryant-equipment/metso/

OEM LEVELS UP WITH

ENHANCED MOBILE WASHING SCREEN

T

erex Washing Systems (TWS) has released the M1700X mobile washing screen to improve efficiency, wear life and ease of reconfiguration compared to its predecessor, the M1700.

Unveiled at Ireland’s Construction & Quarry Machinery Show (CQMS) in late September, TWS business line director Barry McMenamin said the company had continued to build on its reputation for reliable washing plant.

“The addition of the M1700X will enhance an already significant product range offered by Terex Washing Systems, meeting both market and customers’ needs for mobile washing,” he said.

“Our team of engineers have worked closely with our customers to develop improvements to an already high performing machine, such as the new tracked rinser that features a redesigned high fluidisation wash box, increased standard features and improved washing efficiency.”

TWS has designed the new model with a focus on wet processing efficiency, including a 16 per cent increase in spray capacity on all decks, plus a set-up time which averages around 15 minutes.

The improved M1700X features a new integrated high fluidisation wash box to maximise deck efficiency, increase media wear life and have an adjustable spray system.

It also boasts increased standard features, including a regular hydraulic raise and lower for quicker service access, standard hydraulic tensioning, and one-piece catchbox for easy machine reconfiguration.

Setting new standards in screen box technology, the M1700X has a heavy-duty bearing arrangement for long service life, higher levels of screening efficiency and throughput, increased serviceability and maintenance access as well as increased screen angle adjustment that is highly adaptable for feed material variation.

The revamped model is fitted with numerous levels of catchbox sealing, innovative configurable catchbox outlets and configurable blending to maintain material specification.

The M1700X is easily transported, has a quick set up time (typically 15 minutes), and

has optional hybrid power available globally.

Twin- and triple-deck variants of the M1700X are also available.

McMenamin said it was great to be back in front of customers and releasing new and exciting machinery after being sidelined for so long by the global pandemic.

“It was terrific to be back at a show, welcoming customers to our stand, showcasing the capability of our equipment and discussing our latest innovations,” he said.

“We were delighted by how well the M1700X was received and we look forward to building on the connections made at CQMS and discussing how our bespoke solutions can meet their specific needs.”

GLENDUN GETS IT DONE WITH FORMATIVE PARTNERSHIP

To grow its business from the ground up across a majority of mainland Australia, Glendun Group has put its trust in a name synonymous with reliability and performance.

T

he near 10-year-old contractor has recognised that to be the best you must surround yourself with the best, and for Glendun that is Terex Finlay crushing and screening equipment.

No job has been too big or small for Glendun since 2012, conquering the Toowoomba By-Pass and a range of other hard rock, soft rock, sand and gravel jobs across Queensland, Victoria, Western Australia, Northern Territory and South Australia.

Glendun manager Sarah Emery said the Terex Finlay equipment was a terrific calling card for the business.

“We are producing in excess of 240,000 tonnes a month in-quarry, across Australia.

The Finlay equipment is very reliable, operator-friendly, and extremely mobile,” Emery told Quarry.

“Their mobility allows us to move in and out of a blast area all within a couple of hours, ensuring our downtime is minimised and we’re able to get work done as quickly and as efficiently as possible.”

Such efficiency is appreciated of Glendun by a raft of major Australian construction material providers such as Hanson, Holcim, Hy-Tec, Mt Marrow Blue Metal Quarries and Boral.

Emery said the team at Glendun was satisfied working with Terex Finlay equipment, as the machines were equally as reliable as the people behind the design and deployment.

32

Quarry November 2021

“We have a strong reputation based upon our fully qualified staff, with a great understanding of the equipment they’re working with,” Emery said.

“They love [the Terex Finlay equipment], it’s their bread and butter. They’re really comfortable with it, owing to how user-friendly it is and if they have a problem, they can just call up Finlay and get a better understanding or spare part if they need.”

The relationship with Finlay Screening & Crushing Systems, the east coast distributor of Terex Finlay mobile crushers and screens, allows Glendun to keep up and about while the Finlay boffins put in the hard yards behind the scenes. This extends from advice and support to on-call parts delivery.

“If we come across a new spec which hasn’t been asked of us before, they will come to site or pick up the phone and work through all our processes from drilling to screening,” Emery said.

“They’re really good at going the extra mile – we’ve had times where one of their team will jump in a car and bring us the spare part as we need it.”

SYMBIOTIC RELATIONSHIP The relationship spans as far back as Glendun does, when an ex-Finlay sales manager left the company to become a director for the promising contractor.

Finlay Crushing & Screening’s sales and hire manager Ron Bustard said both companies see the connection as more

than just a sales opportunity and their trust enables a more reliable service for Glendun customers.

“We’ve supplied Glendun north of 40 pieces of mobile crushers – jaws, cones, screens and impactors,” Bustard said.

“It wasn’t just a sale, our partnerships are set up as a service and to build our customers up and support them through to success.”

Some Finlay customers have been known to get up to 25,000 to 30,000 hours out of single machines. It’s reliability like this which allows Glendun to go about its business knowing its future is secure with Finlay.

Bustard explained how Finlay goes about its own business, supporting valued clients like Glendun.

“For a lot of customers, especially when Glendun was starting out, we would go and look at a job in-person. I would help and decide what machines would get the job done, and what tonnages it would require so that they could price the job for their customer,” Bustard said.

“We’d then help them get the machines up and running properly so that they were making spec and that’s what helped build the relationship into what it is today.”

Glendun’s unplanned downtime is kept to a minimum, due to companies like Finlay, as the distributor goes out of its way to solve any problem.

“We’ve had the odd machine go down and may not have had the part in stock so we’ve

stripped a stock or hire fleet machine for the part to get them up and running again,” Bustard said.

“I think we go above and beyond to make sure that they can continue running. We know that downtime is like burning money so we do whatever we possibly can for them.”

Glendun continues to optimise its processes with the latest technology, Emery said.

As predictive maintenance becomes more of a necessity than a bonus offering, Glendun will look to combine its systems with Finlay’s for best effect.

“The telemetry on Terex Finlay equipment allows us to track the machines here in our office. We can track their downtime and their idle hours to enhance our predictive maintenance capabilities,” Emery said.

“We’re now looking to integrate this into our own maintenance systems to gain real-time, automated analysis of all our machines.”• For more information about the Glendun Group, visit glendun.com.au

Manufacturers design and build vibrating screens as a total system. The weight of the parts, required running speed and amplitude are all considered when balancing the machine.

FABRICATING FAILURE:

GENUINE PARTS FOR VIBRATORY PLANT One of the ways operation managers naturally presume to increase profits in a mining or aggregates operation is to cut costs. Parts are often an area that production managers eye as a way to save money, but, as Duncan High explains, it’s important to look beyond the price and understand the part that a component is playing in the performance of a vibrating screen and long term productivity.

O

peration managers need to be sure they are choosing the most reliable parts for their equipment. They need to consider the knowledge, experience and resources required to manufacture the part, the potential hazards of using a fabricated version and the value of having the support of the original equipment manufacturer (OEM). Here’s a look at the difference between the two and how those differences can impact production.

OEM EXPERTISE Consider the difference between fabricated and OEM components. Fabrication shops

have come a long way and are often able to produce quality components but some equipment, such as vibrating screens, need such a precise tolerance that a fabricated part might not work correctly, no matter how closely it resembles the OEM version. Only a machine’s manufacturer has the precise equipment drawings, measurements, plus/ minus tolerances, material composition and know-how on what needs to be heattempered. This means only the manufacturer can produce a component that fits those finetuned parameters. Even a reputable fabrication shop with capabilities similar

to that of the OEM has to rely on reverse engineering and guesswork to fashion a replacement. The part may look identical, but if it’s even a little off it could cause problems.

A vibrating screen isn’t so much a machine as a complete system where every component works in tandem to accomplish a specific goal. If an operation screens 1200 tonnes per hour (tph), for example, a manufacturer designs parts with different strength and rigidity than they would for a 200 tph application. This customisation ensures the entire system runs to the proper g-force and is strong enough to resist the

Unlike traditional inclined vibrating screens, it maintains constant g-force — even during surging — so you can achieve optimal material stratification.

forces of the material running over the screen. The weight of the parts, the required running speed plus amplitude are all taken into consideration when balancing the screen. If an operation chooses to fabricate a side plate and the weight is wrong, for example, it could impact the machine’s balance. This could lead to improper motion in the vibrating screen, causing poor stratification of material, lower bearing life, or premature breakage of body components due to improper operation. In the end, this leads to unscheduled downtime, contaminated product, or the required tonnes per hour not being produced.

CALL FOR BACKUP Custom fabrication shops can’t offer the support benefits of the original equipment manufacturer. OEMs usually have the infrastructure to ensure fast, efficient problem-solving. If there is a problem with a part, the OEM will take full responsibility, quickly assess the situation and send a replacement almost immediately.

Most parts shops don’t have the resources for a quick, precise turn-around if the part doesn’t work right, and there is no guarantee the replacement fabricated part will be correct.

In addition, working with an OEM means having a support team

Contributor Duncan High leads a team focused on providing processing equipment solutions to help customers get the highest possible production rates and reliability.

that understands an operation, its production and equipment. They know what parts will wear quickly and what parts need to be on hand to limit downtime. They often offer OEM supplier agreements that ensure they will have critical parts in stock for immediate delivery, limiting or eliminating extended downtimes.

An OEM’s focus on vibrating screens also brings an in-depth product knowledge that’s rare elsewhere. Some manufacturers’ certified technicians test machines as a system before each leaves the factory, and they run the same tests once the vibrating screen has been commissioned to ensure results are identical. They use this information to make sure every component is running at OEM standards, and the machine plus components are backed by a strong warranty program. Not only do some manufacturers offer warranties on new equipment purchases, some guarantee parts for up to a year if an operation uses OEM-certified technicians and parts and performs regular maintenance. Any fabricated parts introduced to a machine during a warranty period will void the entire machine warranty.

HIDDEN PRICE TAG While at first a fabricated component seems to make sense because it can often cost less than an OEM part, those savings are often short-term. Minor imperfections in the

36

Quarry November 2021

part or lower tolerances for the stress placed on the machine can cause the component to fail prematurely, resulting in additional replacement costs on top of unscheduled maintenance. Even while the part is functioning, it often adversely affects the production of the machine, diminishing the throughput and limiting profit potential.

But the potential damage from an imperfect part doesn’t stop there. Those imperfections could start a chain reaction that leads to the damage of a series of other parts. This is especially true for shaft components, which form the heart of a vibrating screen. For example, if the shaft shoulders are not machined within the OEM tolerances, an operation could see problems within hours of operation. This slight difference in size can cause the shaft assembly stack up to be too tight or too loose, leading to excessive heat and/or wear of the shaft components. This can cause bearing failure or premature breakage of shaft components or body components.

This chain reaction of issues could result in maintenance costs far greater than the price of the fabricated component but the cost is compounded by the fact that rarely is the heart of the problem diagnosed on the first pass. Most operators miss the true cause of the problem and begin fixing the symptoms – a cracked panel, a cross member or

sections of screen media. Then the damage is destined to repeat and those parts must be replaced again. These symptoms might become obvious within 48 hours, while the root cause might take a month before it’s realised. By the time technicians find the issue, the cost of the initial part fix could be greatly multiplied and could be much higher than what the OEM counterpart would have cost.

Take tension rails, for example. A customer might wonder why his screen media is breaking after just a week of use, where before it lasted a month or more. An OEM representative visits the site and finds the operation has been buying tension rails from a local fabrication shop to save money.

The tension rails looked right but were not tensioning the screen media properly across the screen deck, causing the sections to break. What saved the operation a few bucks up front on new tension rails cost them thousands of dollars in screen media and downtime for change-outs. In addition, if the faulty part caused the vibrating screen to operate incorrectly, there’s a good chance that the stratification didn’t occur correctly and that materials may have to be rescreened or discarded.

If operators notice a problem soon after installing a fabricated part, they can prevent further damage by shutting the machine

The OEM can offer an in-depth knowledge of an operation’s vibrating screen along with accountability and fast, reliable problem solving.

Imperfections in fabricated shaft components can lead to excessive heat, resulting in bearing failure and premature wear of other components.

Fabricated tension rails, if not built to OEM tolerances, may not correctly tension screen media, leading to thousands in new screen media and downtime.

down quickly. However, this still results in costly downtime, as mechanics order parts and make repairs. Any time the vibrating screen can’t run will bite into profits, particularly for operations in the midst of

production season or a mining operation, where a few hours of lost time can result in tens of thousands of dollars of profit losses.

This cost alone would quickly offset any savings from choosing fabricated parts.

STICKING WITH THE OEM While it’s good business practice to find ways to save money, site managers should not compromise on the quality of vital equipment. The risks of expensive repairs and time wasted are just too high.

Choose carefully when looking at replacement parts. While fabricated components are usually cheaper and may appear to work correctly, any variance could cause damage and downtime down the line.

Continue to work with the original equipment manufacturer to guarantee a supply of reliable parts and the backing of a company with the resources to solve problems quickly. The right choice means more uptime, more profits and the assurance that a part will only make a machine run better. • Duncan High is the division manager of processing equipment technology at Haver & Boecker Canada.

PRODUCER EMBRACES

AN INNOVATIVE AND INTUITIVE FLEET Thanks to a total fleet overhaul, a growing business in South Australia is better equipped to serve the quarrying, recycling, construction, and mining sectors.

A

uscrush (formerly known as SA Crush & Recycle) took the leap to a range of Kleemann crushers and screens, making it seem like one small step, thanks to equipment supplier Wirtgen Australia’s support.

With six machines across four job sites and two more units on the way, Auscrush manager Morgan Taylor said there was one major reason for the transition.

“The aftersales services and support is all there, which is imperative in this industry,” Taylor told Quarry.

“The service from the team at Wirtgen is unbelievable and the machines themselves are reliable, operator-friendly, and the throughput is very high.”

Wirtgen put time and effort into its partnership with Auscrush, running aggflows and sharing ideas on how to optimise

production for the crushing business.

Taylor said he had never experienced the respect and responsiveness afforded by Wirtgen.

“At the drop of a hat, they’ll be available to help us out,” he said. “My team can ring their technicians and be sure they’ll be able to help as soon as possible with understanding fault codes and whatever else might need doing over the phone.”

The Auscrush fleet now includes an MC110R EVO jaw crusher, a MS13Z reclaimer, a MS953 EVO triple-deck screen, a MR130Z EVO2 impact crusher, a MCO11 Pro cone crusher, and the MCO9 cone crusher.

Soon to be added to the fleet is another MCO11 Pro cone crusher and the MS702 EVO double-deck screen, as Auscrush expands into a wider range of campaigns.

These machines are all put to work across

South Australia and Western Australia, working with sealing aggregates, concrete aggregates, ballasts, stemmings, and iron ore.

‘AS EASY AS A MOBILE PHONE’ The three-year-old business had been steadily growing its presence using another brand but Taylor said the move to Kleemann has been seamless for his team.

“The units all work very well together and they’re all very operator-friendly,” he said.

“My team was all up to date with the previous brand, but basically as soon as Kleemann was on site the team picked it up within five minutes.”

Owing to this ease of operation is Wirtgen’s Spective control system.

Ben Lefroy, Wirtgen’s national sales manager for Kleemann in Australia and New Zealand, explained the thinking behind Spective.

Auscrush takes advantage of the Kleemann range’s interoperability.

38

Quarry November 2021

“Spective is our intuitive operation control.

The brief behind it in design was it had to be as simple to an operator as a mobile phone,” Lefroy said. “Morgan and his team moved to Kleemann from another brand and Spective, being very user-friendly, has allowed that transition to be easy.”

Auscrush enjoys the versatility of Kleemann’s diesel/electric options, as it provides a safeguard against any potential malfunctions.

Taylor said Spective enabled less downtime and easy servicing when crushing up to 3000 tonnes a day on some jobs.

“With the electric design, you might save a bit on cost of production, but what I like most is it’s much easier to fix,” he said.

“When the fault codes come up on the Spective screen, it will explain what it is and a number which corresponds to the breaker in the electrical box.

“All we have to do is fix a single breaker or flick a switch and we’re back in action.”

ALTERNATIVE POWER The diesel/electric versatility also allows Auscrush to plug into a power source if the site has that capacity, saving on costs for the client and for Auscrush.

“In this day and age, it’s important to be on top of your fuel consumption and environmental footprint,” Taylor added.

“At Auscrush, we want to move to as close to zero emissions as possible. It’s not only a massive sale point but it’s a moral step in the right direction.”

Besides Spective, and a sturdy support network, Wirtgen has also offered Auscrush the ability to connect on a deeper level to get the most out of each machine.

Lefroy said Auscrush was treated like a partner rather than a sales opportunity, and systems were integrated between the businesses to put everyone on the same page.

“This includes WIDOS, our online parts shop and WITOS, our digital telematics system,” he said.

“We’ve given Morgan these tools to not only improve the ease of his business but to work with us so that we can talk the same language.

“Morgan has embraced that at Auscrush with the business and operation, which we love because we’re all talking Wirtgen.” • To learn more about the Kleemann mobile range, visit wirtgen-group.com/en-au

SPECTIVE CONNECT: A SMARTER FORM OF PLANT CONTROL The innovative Kleemann SPECTIVE digital operating concept has optimised the control options of crushing plants in a trendsetting manner. Kleemann is now going one step further with the SPECTIVE CONNECT extension. All relevant process information and reporting can now be displayed on a The SPECTIVE operating concept: touch panel smartphone without having to leave the directly at the plant, large radio remote control feeding device. for set-up, small radio remote control with all With the SPECTIVE operating concept, operating functions.

Kleemann is now a major leader in the development of user interfaces. The plant is started via the direct 304mm (or 12-inch) SPECTIVE touch panel. The intuitive operating concept makes it simpler for users to choose the necessary settings. Once it has been set, the plant then runs in automatic mode. When a plant train is used, after initial set-up the operator can connect to the complete plant train, not just each individual plant.

As a new feature in the SPECTIVE world, the radio remote controls have been integrated. With a large radio remote control, the plants can be moved from the low loader and the set-up procedure can be carried out conveniently and at a safe distance from the machine. The small radio remote control can be used to execute all relevant functions comfortably from the excavator.

PLANT CONTROL BY APP The diesel fill level, average fuel consumption, average plant performance, gap setting, utilisation rate and a lot more important process data can be displayed at any time via the dashboard. In most cases, operators do not have to leave the driver’s cab or interrupt the ongoing process. They can detect, for example, on the smartphone that the diesel fill level is low and order fresh supplies directly from the driver’s cab.

Operators can see the machine utilisation rate at a glance and therefore regulate loading. They can also receive data on the daily output already achieved and compare it to the previous day.

SPECTIVE CONNECT offers the operator more safety, higher plant accessibility, greater utilisation and profitability and economy. Its other features include: • A plant overview for maximum efficiency. The operator in the driver’s cab can obtain a plant overview of the in-feed and the complete crushing plant via the camera system on the smartphone display.

• A fault message with targeted information. In case of a malfunction, SPECTIVE CONNECT displays not only a general fault but, at the same time, the corresponding components, including troubleshooting aids. The smartphone can be taken to the location of the fault that occurred and support the operator step by step with fault elimination.

• Process optimisation through detailed reporting. The SPECTIVE CONNECT app automatically generates clearly arranged reports on consumption and plant performance as well as the plant usage. These reports can be forwarded by messenger or email. This guarantees transparency in the complete process for the plant operator.

SPECTIVE CONNECT from Kleemann is currently available as an option for the new MOBICAT MC 110(i) EVO2 jaw crushing plant and the new MOBICONE MCO 90(i) EVO2 cone crushing plant. Further SPECTIVE machines will be equipped or retrofitted with this gradually. The app can be installed on iOS and Android smartphones.• To learn more about SPECTIVE Connect, visit wirtgen-group.com/en-au

REVAMPED HAULER

EXUDES SCOTTISH GENIUS, RESILIENCE Amid Scottish pomp and ceremony, the Rokbak articulated hauler range has been launched for the extractive industries worldwide. As Paul Douglas tells Quarry, the revamped product is underpinned by a rich and proud Scottish history of resilience and perseverance – qualities that will drive its future.

T

he city of Motherwell lies between Glasgow and Edinburgh, in Scotland’s south. The city is famously the closest the Roman Empire ever came to occupying the Scottish homeland and its name derives from a well – the Lady Well, which was dedicated to the Virgin Mary.

Motherwell was an agrarian community until the mid-19th century when it became part of the Industrial Revolution. From 1848, when the railway was introduced, to the 1930s, Motherwell was a hub for iron and steel works and a producer of munitions and components for trams, railways and bridges.

Motherwell’s steel industry was nationalised in the 1950s and at one time was producing three million tonnes of steel per year. By the 1970s, more than 13,000 people were employed in the steel works.

Motherwell also became renowned for its automotive works, producing cars, trucks and buses. A British national steel strike lead to the decline and eventual closure of most of Motherwell’s automotive works in the 1980s and in 1996 the city’s steel works closed, bringing to an end almost 400 years of

Scottish iron production. Motherwell and the neighbouring town Wishaw are today homes to a thriving service-driven economy.

However, amid the industrial gloom of the late 20th century, an automotive stalwart survived Motherwell’s overhaul and continues to thrive today.

In 1950, Euclid Great Britain, a subsidiary of US earthmoving equipment manufacturer Euclid of Ohio, had opened the doors to an off-highway truck manufacturing plant in Motherwell.

In just four years, Euclid’s Motherwell factory constructed more than 1000 offhighway trucks and continued to grow.

By 1968 Euclid’s earthmoving division had rebranded itself to Terex and by 1982 Motherwell engineers had designed, tested and manufactured Terex’s first ever model 3204 articulated dump truck (ADT).

Terex Trucks (as it would become more popularly known) launched its renowned TA (articulated) range in 1998 and 10 generations of this ADT, fitted with Scania engines, have been distributed around the world, including Australia.

In 2014, Volvo Construction Equipment (Volvo CE), which was eager to obtain rigid hauler expertise, bought Terex Trucks, setting up the former Terex brand for an exciting new era – and continuing the Motherwell factory’s fascinating story. Since April 2018, the Motherwell factory has been producing Volvo CE’s rigid hauler product line (with Terex Trucks’ former rigid hauler products being integrated into the new Volvo CE line). In early September, Terex Trucks and the factory were rebranded under the new moniker of Rokbak.

REBRANDING AN ICON Paul Douglas, the managing director of Rokbak, is a Motherwell native who has very fond memories of the former Euclid/ Terex manufacturing facility. “I was born five kilometres from the Motherwell factory,” he told Quarry. “I started my career in this industry 35 years ago in the factory. My parents still called it the Euclid plant for a long, long time, and over that journey, it’s been a fantastic employer. You’re talking tens of thousands of people who have worked here.”

Rokbak managing director Paul Douglas is a Motherwell native who cut his teeth in the industry as an engineer in the former Terex Trucks factory.

Douglas gained plenty of experience working inside and outside of Motherwell. He has worked across the off-highway plant and

equipment market for the whole of his 35-year career. “I spent 16 years with Komatsu, then with Terex Trucks and now with Rokbak,” he said. “I’ve had other roles in manufacturing and production planning, and the aftermarket segment. I ran the aftermarkets division of Terex for a couple of years, and then in 2005, I came back into the trucks business at a senior management level. I’ve spent 11 years running the business. I have a long association with the team, and the offhighway industry.”

He said the acquisition of the old Terex Trucks business by Volvo CE marked a huge opportunity for the division and also a new lease of life for the Motherwell factory. “We came out with an owner that was prepared to invest in the people and the products,” he said. “That was the start of the journey to the Rokbak rebrand. Volvo CE allowed us to make major improvements in every part of our business. Millions of pounds have been invested in improving our products,

modernising our facilities, expanding our network, and developing our people. It has been a process of continual evolution.”

Douglas said the Rokbak trucks will have an important part in the Volvo Group of companies’ overall ambition to reduce the total emissions of Volvo products by 35 to 45 per cent by 2030 and achieve zero emissions by 2040. Further, Rokbak’s Motherwell factory now gets all its electricity from 100 per cent renewable energy sources and is following a science-based path to reduce carbon emissions in its manufacturing processes.

Douglas said that upon acquiring the former Terex Trucks division, Volvo CE was careful not to rush into a major branding overhaul.

“Volvo took a long look at where the business was at,” he said. “It didn’t want to destabilise the company or make many sudden changes too soon. It assessed what had to be done to make the company safe and stable, and best utilise its personnel. When we were carved out of the Terex Corporation, there

were certain functional gaps because the resources we used were part of the greater Terex company, and they didn’t come across with us. We had to add resources in the sales and the marketing area, and it was about ensuring that we had the right people and the expertise. Part of the acquisition was also looking at the product agenda. What was the multi-generation roadmap? It was also important that our dealer network wasn’t destabilised. In the first three years, dialogue had started with the dealers about rebranding the product.”

Douglas said that work on the rebrand escalated in 2018. “The development of a new brand is exciting, and what surprised me was that Volvo had never previously created a completely new brand from scratch,” he said.

“I had no idea how extensive a rebranding exercise would be. There’s many financial and legal dimensions. It’s a huge project and it took more than two years. From late 2018 and into 2019, we started to knuckle down and decide what the new name was going to be.

“We had a long list of 52 names and, with a lot of great work, whittled that down to a shortlist of three. We had to make sure the name would translate safely into other languages. Rokbak came out of that work as the strongest. It’s a great name, it really pops out, particularly the way it appears on the truck. It’s a clean brand name, it’s not being used elsewhere in the world. In the test forums Rokbak resonated with some of the dealers and their customers. It conveyed the impression of the product of being ‘rock solid’.”

‘MODEL UPGRADES’ While the name is a departure from the usual Terex Trucks and Volvo CE labels, it should not be construed that the Rokbak products are radical departures from the 28-tonne payload TA300 and 38-tonne payload TA400 articulated haulers. In line with the new branding, these haulers have now been recast as the RA30 and the RA40 respectively, complete with new shades and livery – a sand colour, compared to the white of the old TA trucks.

The RA30 has a heaped capacity of 17.5m3, is powered by a Scania DC9 engine with gross power of 276kW and its maximum torque is 1880Nm at 1400 revolutions per minute (rpm). The RA40 is powered by a 331kW Scania DC13 engine, its maximum torque is 2225Nm at 1300 rpm and it has a

heaped capacity of 23m3.

Both vehicles feature fully automatic transmissions with manual over-rides and retarders and heavy-duty axles with fully floating axle shafts and outboard planetary reduction gearing. The RA30 is equipped with eight forward gears and four reverse gears, ranging from five kilometres per hour (km/h) to 55km/h, while the RA40 has six low and high speed forward and reverse gears, from 6km/h to a maximum 64km/h. The three axles are in permanent all-wheel drive (6x6) with a differential coupling between the front and rear axles. All hydraulic braking systems are fitted with multiplate-sealed and oil-cooled brake packs at each wheel, with independent circuits for front and rear brake systems.

Douglas described the RA30 and the

RA40 as more “model upgrades” on their predecessors than a complete revamp.

“We’ve done transmission changes on the 28-tonne and 38-tonne models. There were changes in the cooling and exhaust systems that will comply with Tier 2 and Tier 4 emissions systems. We’ve updated the Haul Track telematics system and the on-board weighing systems.

“These are soft packages,” he stressed.

“They are not new trucks but they are model upgrades. There will be major upgrades in the future.”

The new transmissions and engines are expected to make this latest generation of trucks up to seven per cent more fuelefficient. Douglas said the incremental changes made to the trucks are designed

to address the costs of ownership and were adopted in response to customer feedback about the old Terex Trucks brand.

“Most of the improvements are driven in fuel efficiency – by about five per cent - on the RA30,” he explained. “The EU Stage V engines offer another three per cent fuel efficiency for European customers. The customers want lower fuel costs, more efficient machines.

For the telematics system, the customers requested more connectivity and wanted information sent to their central systems more easily, so we had to integrate the on-board weighing and the telematics systems.

“There have also been some refinements to the cab. The operators are now having more of an influence in the product purchase because they’re the ones who know the vehicles inside-out. It’s about providing comfort and well-being for the operators that are working in them for up to 10 hours a day. There was also a request that the product be kept simple in its operation and maintenance.”

Given there is already a quite competitive global market for articulated haulers, including from Volvo CE’s own popular ADT range, Douglas concedes the customer is very spoiled for choice. However, he believes Rokbak has numerous upsides as well.

“We have a strong focus on uptime and a low cost of ownership,” he said. “Under the Volvo Group we have invested substantially in both our products and the manufacturing process. Our focus is always on ensuring we

44

Quarry November 2021

deliver the highest quality.

“Another factor to consider is that we only build articulated haulers and we have a small range. So what we do, we do very, very well.

We also put a lot of focus on relationships, and we are always there to support customers and dealers.”

This support will extend to the owners of legacy Terex Trucks, which will be supported

by Rokbak’s dealer network. Even if the truck owners do not automatically upgrade their vehicles, they will continue to be valued members of the Rokbak “family”.

“Most parts will be interchangeable,” Douglas explained. “When you introduce a new model, there will always be some crossover between the old and new. We’ve opened a spare parts hub in America, so along with the Motherwell factory and our dealer network, there will be several main logistics hubs that we will use for parts support.”

DEALER ARRANGEMENTS The first generation Rokbak haulers introduced to Australia will feature Tier 2 engines as standard, in compliance with Australian diesel fuel regulations for non-road vehicles. However, customers will also have a choice of US EPA Tier 4F or EU Stage V engines. Porter Group, which has been the distributor of the Terex Trucks articulated haulers since 2017, will represent Rokbak in Australia and New Zealand.

“We have a very collaborative relationship with our dealers and from about 12 months

before the brand launch we were consulting with a number of them in select markets,” Douglas said. “We asked Porter and others for their perceptions and feelings around the new brand, and it helped guide our thinking through the process.

“We don’t have a huge number of dealers in the Asia-Pacific region, so I’m optimistic we’ll get great coverage from Porter. Their feedback has been excellent.”

As part of the virtual brand launch program in September, Porter Group’s Australian national sales manager Michael Carter said in a message to Rokbak’s customers, dealers and personnel that Porter had enjoyed growth with the old Terex Trucks brand and was looking forward to building on that experience with Rokbak.

“Since our appointment, we’ve introduced a lot of our customers to the product,” Carter said. “We’ve sold machines throughout Australia, New Zealand and Papua New Guinea, into a range of segments, including quarrying and mining, as well as recycling.

Our general feedback on the trucks is that they are a very well built, reliable product, with tonnes of power.

“Porter Group has invested significant amounts of money and time in training of our staff, including sales, service and parts departments. We’ve also put a lot of parts on our shelves to keep our trucks going for our customers. The result of this is improved sales and in fact year on year our market share has doubled. At present, we

have trades from many of our competitors including Komatsu, Volvo, Bell and Moxy, as well as Terex. This shows that we are making significant inroads.

“The Porter Group has also invested in the product through its hire department,” Carter continued. “Between Australia and New Zealand there are over 50 trucks being hired at the moment and they comprise both TA300s and TA400s.

“The Terex brand had a reasonably chequered history in Australia prior to our appointment and because of that we are excited for the change of brand and we are looking forward to the future with Rokbak,” Carter concluded.

RETURN TO MOTHERWELL Douglas said that a key factor for Rokbak in growing its business worldwide is to build a stronger dealer network in the markets where sales have not been quite as favourable. “We are very strong in some markets – including

North America and New Zealand – but in other markets we definitely see opportunities for improvement. This was actually part of our thinking with the new brand.

“We are ambitious in our goals and want to grow, so we’re targeting increased market share as we move forward. Our investment in our products will continue too, as that will be a crucial part of helping us achieve our ambitions.”

Douglas said he would like Rokbak and Porter to work more closely to engage the interest of Australasian customers in the new Rokbak haulers in the future. However, the global pandemic of the past two years has been a source of frustration for the company, with many events and promotions in the final quarter of 2021 having to be postponed or cancelled. Douglas expressed his hope that some of these events and promotions may be rescheduled for 2022, and that even customer tours of the Motherwell factory might resume again.

“We have started to make preparations for the factory to start receiving visitors again,” he said. “When those visits resume, then we would love to bring the Porter customers to the factory and show off our passion that the Rokbak products are being made.”

It would not only be a celebration of the achievements of the almost timeless Motherwell factory over a period spanning more than 70 years but a glimpse into an exciting future for the Rokbak business.

Much like the town that spawned it – and the robust products that it produces – Rokbak is proving to be an example of Scottish endurance, resilience and ingenuity in an era of global disruption and uncertainty.

There are plenty of companies and nations that can draw inspiration from Rokbak’s and Motherwell’s examples.• To learn more about the Rokbak brand, visit rokbak.com For more information about Porter Group, visit porterce.com.au

VICTORIAN FIELD

SPECIALISTS KEEP CHANNELS OPEN COVID-19 has been a torrid time for producers and suppliers alike. However, professional engineers for a conveyor solutions supplier have held their heads high and maintained important communications channels with their long-term clients to ensure that the extractive industry does not miss out.

T

he past 20 months of the COVID-19 pandemic have presented challenges for Kinder Australia’s Victorian Field Applications team but the company’s “dynamic duo” of Tim Storer and Peter Laskey have stepped up to provide solutions for their bulk handling customers.

For Storer and Laskey, perfecting delegation skills and getting used to virtual and physical meetings with restrictions has been crucial to keep communication lines open with customers.

“My travel within Victoria has not been as impacted as other states with border closures,” Storer said. “There have been a few that have been abiding to a ‘No Visitor’ policy, and that has been difficult. Email campaigns and online follow-ups have been key to avoid being out of sight, out of mind.”

Storer has a flair for creativity and a knack of keeping engagement and morale levels high with his exuberant personality and delivery.

He enjoys hosting demonstration webinars for customers and as staff training, keeping them technically informative, but stressing the key points with ease. He always prompts for questions people may have and encourages two-way communication.

“It is vital that we stay connected with staff and customers,” Storer said. “It ensures we can progress, support and learn.”

Storer has an eye for design, problem-solving and detail. He is skilled in photography and videography – snapping photos of Kinder’s

products in action on site, and providing marketing material and a look into Kinder solutions in motion.

Kinder’s YouTube channel (youtube.com/ user/kinderandco) is populated with many of Storer’s compilations that he has meticulously created with his video-making ability. A recent one featured the K-Superline engineered polyurethane where he showcased Kinder’s custom water-cutting capabilities with clever use of macro, fast motion and stop motion videography.

For Peter Laskey, who is the most recent recipient of the IQA’s Supplier of the Year Award, the pandemic has meant a little more sedentary work than he would like. However, he has been thankful for the site visits he has performed with Kinder’s authorised “to work” status during the 2020 and 2021 lockdowns.

“Challenges for my customers have varied,” he said. “Kinder’s Victorian customers have continued to work in a very smart, safe way.

There have been subtle changes in work practices to keep sites operating, and safe.”

Like Storer, Laskey believes that communication has been key to keep the wheels turning in these unprecedented times.

“We have communicated to our customers to reassure them that we are operating at full capacity, even at our home base,” Laskey said. “There is always the ability for us to solve issues with the assistance of video call platforms, phone and email.”

Customers are drawn to Laskey’s genuine and personable demeanour and trust his expertise when it comes to solutions for their site. With a background in construction work, Laskey has the experience and product knowledge. Being solutions-driven, his role focuses on improving site equipment utilising Kinder’s wide range of technology.

“We’re mainly looking at situations at the transfer sites with skirting issues - if there’s spillage. We also help with belt tracking as well,” he explained. “I started at Kinder in 2011 as a warehouse supervisor and that’s where I gained a lot of product knowledge.”

For Tim Storer, Peter Laskey, and the rest of Kinder’s sales and eEngineering team, it is about communication. Open, honest communication is paramount for people to trust a business – “trusted quality” has been part of Kinder’s vision and values for 35 years.

CEO Neil Kinder agrees that building trust with customers allows the true site productivity issues to rise to the surface. It becomes a “winwin” for both the supplier and the customer to develop the products that the industry needs.

“When learning your industry, you need to understand the main issues that are being faced by your customers. What problems are they wanting to solve? This will enable you to focus on the right products – tackling dust and noise are a prime example of this.” • To learn more about Kinder Australia’s inventory, visit kinder.com.au

DUST CONTROL

EFFECTIVE, FRIENDLIER SOLUTIONS FOR DUST SUPPRESSION

A key supplier to the extractive industries in the prevention of airborne dust emissions from quarrying processes is undertaking a research project to determine the most effective solution with the least amount of effort for quarry producers.

P

olo Citrus continually listens to its customers to better service their needs and improve solutions. Service is a priority; the company has long prided itself on developing personal relationships with producers and coming to the discussion with a wealth of industry knowledge. Each installation is different, including the material, the weather, the machinery and the staff. Polo Citrus considers all these factors and works with producers to provide the most effective solution to their dust problems. The company follows up with its customers, taking on honest feedback and not shying from difficult situations.

A key component of Polo Citrus’ offerings is the regular servicing of units, which helps maximise cost savings and ensures the equipment works with minimum water and Polo’s product for maximum results. Regular servicing also ensures producers protect their staff, communities and equipment with environmentally friendly products and comply with Environmental Protection Agency regulations and other regulatory guidelines.

This is completed on-site in real time with photos and data. This type of preventative maintenance helps improve equipment life and avoid unplanned issues that can cause downtime.

As an industry, there is now a greater understanding of the issues surrounding the generation of fugitive dust. Dust can cause many health issues varying in severity as well as visibility problems and safety hazards. Excessive dust can also be carried on clothing and transported home, affecting others outside the workplace. Machinery can also be damaged by dust which can cause wear, blockages and engine damage. There are also environmental concerns around dust and its impact on plant and animal life in surrounding areas. A layer of dust on the leaves of plants can hinder photosynthesis and this disturbed plant growth can then impact other food chains and the overall biodiversity of the area. The control of dust on extractive sites is a priority and serious concern, so Polo Citrus has commenced a research and development project to provide the most effective solution with the least amount of effort for the customer.

FOAM QUALITY Polo’s research and customer feedback determined that on some sites the biggest challenge is maintaining the quality of foam.

There are several factors that come in to play.

First, the water source can be unpredictable; the water can vary from high pressure to low pressure or no water at all. Second, Polo Citrus provides a lockable cabinet with a key so on occasion it can be accessed to check if the filters need cleaning, parts replaced, or air or water pressures changed. Unfortunately, these keys get lost, or the cabinet remains unlocked and staff make changes outside of Polo’s recommendations that cause

problems to the foam quality and overall dust control.

Polo Citrus’s first priority was to stop the variability of the amount of product (BDS) in the foam due to factors relating to water pressure and staff intervention with the set controls. One of Polo’s key partners has been able to source a self-regulating pump that will monitor and adjust when and where necessary the amount of BDS in the water, to ensure that the percentage of Polo Citrus product in the water remains the same. This has a flow-on effect to Polo’s customers’ confidence, in both their site dust control as well as ensuring their finished product is within specification.

The research and development project entailed on-site testing at the Polo Citrus manufacturing facility at Sunshine West in Melbourne. The company’s fully operational test rig was pushed to its limits with a wide range of water flow and foam generation.

The generated foam was collected and these samples were analysed for total solids content and compared to Polo’s standard

product, currently used on extractive sites.

The results undisputedly demonstrated that when the water pressure was reduced and increased, the foam generation stayed similar. The dosing pump slowed and sped up, dependent on the water flow rate. If the flow rate of the water varies on the producer’s site with this new pump system, the concentration of Polo’s products remains consistent, avoiding an oversupply of BDS in the end product and poor foam generation due to excess or insufficient water caused by water flow changes. Polo’s main objective for its customers is to produce consistent quality foam which provides highly effective dust control.

REMOTE CONTROL SOLUTION An in-depth study comparing all results and final sign-off was given to the dosing unit. The results of the trial with some key customers will be released in January.

A previous R&D project determined that the Polo Citrus dust suppression system required the operator to be able to start and stop the foaming unit when necessary. The research showed the feed material can be intermittent, due to blockages or the way the material needs to be handled. It became obvious that that a remote system was essential to avoid wastage of the Polo Citrus foam and over-saturation of the belts with foam when there was no material. Polo Citrus now has the option to fit all of its units with a remote system that can be operated by the driver in the cab or control centre, without the safety risks of manually shutting off the unit on the working floor.

Polo Citrus is focused on providing highly effective dust suppression by making it affordable and readily available to all sized businesses.

The company uses its industry knowledge rather than expensive engineers to design systems and works with clients to customise the best solution. •

We’re reaching new heights in engineering.

CREATING A CENTRE OF EXCELLENCE FOR MINING

W

ith a vision to use technology, time and talent to advance the smarter use of water and look to a future where global water issues do not exist, Xylem has launched its new Global Mining Centre of Excellence to support and solve water challenges in the mining industry.

Xylem uses the catchphrase “We solve water”, a foundation on which its Global Mining Centre of Excellence (CoE) is built on.

The new mining CoE is an assembled team of experts with vast experience on the water cycle in mining.

Global Mining CoE director Paul Gaby said the centre was created to support Xylem’s regional teams to become a water management partner to its customers for all water touch points on a mine site.

“While there are multiple Xylem locations with strong knowledge of mining applications, the mining CoE will also support the collaboration of all the successes and previous learning across the globe in mining,” he told Quarry.

“Mines are under more pressure than ever to reduce their impact on the planet and regulations continue to change. Companies that take a strategic view of water in mining applications have a better chance of turning these systemic challenges into competitive opportunities.”

Gaby said this is where Xylem’s CoE stands out – with key support functions such as application, technical, product integration, product development and design.

He said through its team of mining application and design engineers, Xylem can support customers to work through the

toughest site water challenges.

“From a basic selection right through to a large complicated application, we can provide support for long-term projects, to tenders or even emergency responses,” Gaby said.

Through global customers and Xylem’s key mining stakeholder feedback, the company aims to develop details of product gaps in mining to build a case from the ground up for development in global research and development (R&D) centres.

Gaby said with the ongoing changes in water management practices, there will be a need to couple Xylem’s offering with varying installation, product and management needs that the CoE can manage internally with experienced design engineers.

“We want to continue developing an intimate knowledge of the mining water cycle, and the voice of customer, to subsequently continue developing new products, technologies, and accessories that improve our customers’ experience dealing with water challenges,” he said.

Xylem’s extractive industry solutions serve open pit, underground and processing operations.

Gaby said the company is committed to including digital, transport, treatment, monitoring, control and assessment technologies to make mining operators’ jobs easier and their mines safer, reliable, and efficient throughout a mine life cycle of exploration, development, operation and reclamation.

As a result, Gaby said Xylem doesn’t just have great products, but great employees

with years of experience in mining applications to enable the company to become a water management partner to the client and solve water challenges as they present.

“When new unseen issues present, our team will work in the background to solve the issue to then be available whenever this problem may arise again on a global basis.

Being central in support we can also highlight gaps or problems that require product development,” he said.

“We can then work with our research and development teams to develop, improve or combine to find the ultimate solution for our customers.”

As mining is an important industry to Xylem and the Australian economy, Gaby said there is an increased demand in the commodities sector to make environmentally friendly products, focus on environmental social governance and climate change impacts.

He expects the Mining CoE to grow and expand into major mining locations across the globe to help solve their water challenges.

“Xylem’s overall goal as a business is partnering with our customers to provide sustainable, clean and affordable water to more people around the world while protecting the environment,” Gaby said. “All of our customers have environmental social governance targets that Xylem can support to achieve.”

With Xylem’s core values around solving water challenges for its customers and the planet, Gaby said the company is excited to see the investment and commitment Xylem is making to the mining industry.

“By partnering with our various stakeholders – customers, suppliers and industry – we are continuously working towards this objective, and we have a team of dedicated and talented employees who share this mission and journey,” he said. “We are here to solve your water challenges.”• For more information about Xylem ANZ’s products, brands and services, visit xylem.com/en-au

POWER TRANSMISSION TURNS HEADS

S

KF has expanded its primary offering of bearings, seals, and lubricants with a range of power transmission (PT) solutions. As a leader in the parts that make industry tick, why not put them all together?

The number of moving parts in a quarry can be overwhelming for some while presenting a challenge for others. SKF sits with the latter and solves the issue with 114 years of expertise and a customer-specific focus.

The manufacturer works with its partners to not simply replace components but to understand the causes and repercussions of any issues a system experiences.

“A customer may come to SKF with a concern on a bearing, and when investigated sometimes it is as obvious as alignment, or a seal arrangement, or a lubrication issue,” Lloyd Brown, SKF’s contract manufacturing and quality manager for power transmission, told Quarry. “However, it is not at all uncommon that when investigated we find the transmission surrounding the bearing is at least contributing to or completely causing the problem.

“Sometimes conditions of the processes or the equipment have changed (such

as speed, loads, temperatures, humidity) but the corresponding transmission components remain with the original and now inadequate design.”

These pain points can cause premature wear, vibration and failure of components in a domino effect throughout the plant.This encompasses many areas of a quarry’s operations, such as a high speed, low torque pump and fan drives, as well as higher demand drives on cone crushers, ball mills, hoists, elevators, conveyors and blowers.

To address the various needs of quarrying plant and equipment, SKF PT solutions are extensive. A new range of XP2 V-belts caters to high power belt drives, while heavyduty roller, mill and conveyor chains and sprocket drives provide abrasive assurance.

“We also offer flexible shaft couplings that are perfect for quarries and mining such as our grid couplings, gear couplings, disc couplings, or our elastomeric SKF Flex tyre couplings, FRC couplings and even jaw couplings,” Brown said. “Additionally, our range of standard shaft bushings include taper bushes, QD bushes, and our FX keyless locking devices commonly used in conveyor drum pulleys.”

To understand the solutions its customers require, SKF prides itself on its Rotating Equipment Performance program, a longterm contract which combines SKF technologies, failure detectability and reliability services into an integrated package.

The program enables customers to evolve from a capital expenditure model to an operational model and can be scalable from a single unit of rotating equipment to a full industrial plan.

Key performance indicators are defined according to the real situation of critical assets and linked with agreed savings and rotating equipment performance indicators.

The overall goal is to reduce the total cost of ownership of rotating equipment over an agreed period. Part of the savings result from increased machine availability, and part from the reduction of capital outlay

by optimising spare parts inventory and minimising waste.

“With SKF’s product offering of bearings, seals, lubrication and PT, combined with our portfolio of condition monitoring capabilities and our vast experience around rotating equipment, we can offer improved service life and predictive maintenance to increase efficiencies and reduce costs,” Brown said.

To ensure the quality of its products match these core values, Brown said SKF PT products meet a range of recognised compliance standards, eg ISO/DIN, ANSI/ BS/AGMA, RoHS and REACH. “SKF PT components are fully compatible with other manufacturers’ components on the market that meet these same rigorous standards,” he said.

“Granted our SKF main core product is the bearing, the full transmission system has a direct influence and impact on the performance and service life of the rotating shafts and bearings. You are assured the products you use meet the same strict quality standards the SKF brand name stands for.”• To learn more about SKF PT products, visit skf.com/au

WEIGH SCREWS A VIABLE ALTERNATIVE TO CONVENTIONAL WEIGHING TOOLS

A

ctive Weighing Solutions (AWS) has taken decades’ worth of industry experience to perfect its weigh screw conveyors and feeders, assuring quarries of accurate materials handling.

Tried and tested in a range of industries from agriculture to concrete batching, the manufacturer’s weigh screws are borne from a history of working with major construction materials suppliers.

AWS managing director Nigel Saul told Quarry this experience allowed his business to show the industry the value of weigh screw conveyors and feeders.

“Over the years we were supplying belt weighers and weigh feeders to industry around Australia,” Saul said. “One of the common issues people find in implementing belt weighers is simply incorrect installation – some people just put them in the wrong place. So, we provide that knowledge to get the best out of the product.”

These installation issues can lead to errors in accuracy leading to wasted time, money and faith in the equipment. To remove the risk of incorrect installation, AWS will work through it with clients from concept to sign-off.

“We can either go to site or they’ll send us some drawings of their set-up and we will propose a solution to optimise the equipment,” Saul said.

“Sometimes a weigh screw conveyor or a feeder isn’t suited to the application. If an operation has a product with a dramatically varied feed rate, then we’ll suggest something like a batch weigher which is another tool in our arsenal.

“We don’t force a weigh screw conveyor down people’s throats. We inspect the application, learn what the client wants out of it, what they’re looking to spend and then we come up with the best economic and engineering design for them.”

Saul said AWS’s weigh screws were able to deal with even the toughest of materials like cement to achieve accurate operations.

“Cement is one of the harder products to work with for a weigh screw because the material handling characteristics of the material make it difficult, but we’ve proved we can get good accuracy out of our weigh screw feeders,” Saul said.

AWS’s weigh screw is sealed to reduce dust or toxins.

“One of our clients recently requested to weigh cement at 40 tonnes per hour. We achieved an accuracy better than 0.1 per cent of cement to dry aggregate.”

Another benefit of the weigh screws is in their design, which can be key when dealing with materials like cement.

“These products also lend themselves to dusty and toxic applications as they are completely enclosed,” Saul explained. “If you’re trying to contain a product to keep workers safe from dust and fumes then weigh screw conveyors and feeders are an option.”

Having understood its customers and the work they’re looking to achieve, AWS applies its technical knowledge of dynamic weighing and material handling in its designs.

Saul said while the concept of the weigh screw is hardly novel, value is created by AWS’s knowledge of the intricacies of each application.

“We can all weigh. Putting a load cell into a system and coming up with a weight isn’t the problem,” he said. “But understanding the materials handling characteristics of a product is where we shine.

“When you understand a product and how it needs to be moved, only then can you put a system together like our weigh screw conveyor.”

Once the system is in place, AWS offers onsite servicing or remote monitoring to provide technical expertise when it is not practical or possible for on-site support.

Saul explained the simplicity of remote monitoring which allows AWS to come online and help a client in need.

“It consists of a small modem and antenna at the client’s site. All they have to do is plug in the modem and our team from the office or at home can dial directly into it via a VPN,” he said. “We can upload all of the system parameters and operational data in real time, and analyse the data to optimise their system.”

Once logged on, AWS’s remote team can assess the weight signal of the equipment with information coming through at about 100 times a second. This provides an accurate picture of the weighing operation from anywhere with an internet connection.

But for those occasions where a little more information is needed to diagnose any issues, Saul said a solution is on the way.

“We also have options in the works which include a camera for us to physically see what’s going on to better help the client,” he said. • For more information about the weigh screw conveyors and feeders, visit the AWS website: activeweighing.com.au

TRUST IN LEADERSHIP AND EMPATHETIC RELATIONSHIPS As part of the recent commentary on the characteristics of effective leadership and the four attributes of trust, IQA CEO Kylie Fahey discusses the importance of empathy in both life and business outcomes.

E

arlier this year, the Institute of Quarrying Australia (IQA) invited me to present a monthly article, based on one of the seven core characteristics of effective leadership.

Rather than write all seven of these scenarios myself, I chose to invite a number of people to make a contribution, from a diverse demographic and a number of industries, which I hope you have found interesting.

This is the seventh chapter, with a personal story from Kylie Fahey, the Chief Executive Officer of the IQA, who selected empathetic relationships for her stories on becoming an effective leader.

I suggest that you find a comfortable spot to sit and enjoy a coffee while you read this enlightening piece.

I offered the following brief explanation for Empathetic Relationships in my book: Empathetic leaders have the ability to recognise, understand and share the thoughts and feelings of another person. They acknowledge the story without judgement.

Mike Cameron

EMPATHETIC RELATIONSHIPS – KYLIE FAHEY I was very humbled when Mike asked me to write a story on empathetic relationships.

Empathy is an extensive concept and when I started to reflect on the topic, I realised just how complex empathy and being genuinely empathetic is. I have deliberately raised the notion of genuine empathy and will come back to that later. This story is a little about my journey in developing an understanding of empathy and knowing how powerful and important it is in achieving outcomes in business and in life. It also acknowledges that our ability to engage in empathetic relationships requires a willingness to constantly reflect, learn and adapt.

Empathy may be summarised as the skill of

recognising and understanding others’ needs, feelings and perspectives. In any meaningful human relationship this is important. The ability to empathise means you have an awareness of the other person’s feelings and how they impact their perception. Being empathetic does not mean you have to agree with their views or perception. Rather, being empathetic means that you are willing and able to appreciate what the other person is going through.

I have had the absolute privilege of working with some of the least empathetic people and others who are genuinely empathetic and a true inspiration. Experiencing the spectrum of empathetic behaviours during my career spanning nearly 30 years, I have learnt the true value of relationships built through empathy and the outcomes that those relationships bring.

My career kicked off in my twenties and I undertook a variety of roles. I was the “yes” person. If there was a project going or an opportunity to do more I said “yes”. I was not cognitively climbing the corporate ladder, I just

wanted to work hard, constantly work on new things and learn as much as I could. I took every opportunity and often jumped in boots and all.

I accepted a promotion into a public affairs role, an area in which I had very little experience. In my second week, I was tasked with preparing briefing papers and speaking points for my manager to give a live interview on ABC radio about a highly sensitive and very contentious issue. I knew the topic. I knew the angle. I knew the defence tactics. And I knew that I had thoroughly briefed my manager. At 8.57am, I was pushed overboard with no lifering and told by my manager that I was doing the interview – live and on air in three minutes.

There were a few more “ums” during the interview than I would have liked, but I got the key points across and survived. Most importantly, I learnt a valuable lesson that is critical in building and maintaining empathetic relationships. Everyone has fears.

Seniority does not mean you are fearless and do not doubt yourself. I realised it was fear of failure that caused my manager to behave like that. Often leadership is associated with the CEO, a captain or board directors. Hierarchy does not equal leadership, and leadership does not equal empathy.

Building empathetic relationships requires us to acknowledge our own limitations and confront our own fears. You need to get

outside your comfort zone to push yourself.

By doing this you create opportunities to develop emotionally. Some of the challenges I have taken on include stand-up comedy and endurance sports. These things scare me.

But they force me to overcome that voice that says “I can’t”. By getting outside your comfort zone you will find that you can achieve many things. You will develop a deep understanding of yourself and this will help your ability to empathise.

As a middle manager climbing the ladder in my twenties more often than not, I had a very clear preconceived notion of how things should be done. Looking back this was a very narrow position to take. In my mid-thirties my anatomy finally decided to work the way it was supposed to, and I began using two ears and one mouth.

I began to listen. I started to realise that to form a relationship, much less an empathetic one, you need to listen. Not just to what the person is saying, but to what they are not saying, the words they use and do not use and their body language while they are saying it. I realised that by listening you actually get a deeper sense of the issue, an ability to understand and make better decisions. Listening resulted in a huge shift for me. All of a sudden the opinions of others were genuinely influencing a better outcome. When you take the time to understand what those around you need and build relationships based on these needs and feelings, as opposed to what you perceive is required, you get a much better result. I have a silly saying: “A + B = C and C is always better.”

This is about seeking diversity of opinion and understanding the tangible and non-tangibles in any situation and being emotionally aware of what is happening for the people involved.

property. Graduated with a Master of Business.

Completing an invitational leadership course.

Endurance sports. International travel. Busy!

Busy! Busy! So busy. I was busy being busy.

So busy I did not realise that I was failing to display empathy in most of my professional relationships. It was like I was racing to the finish line, but I did not know where or what the finish line was. I was not taking the time to empathise and listen. So I made a conscious decision to slow down. Slowing down is not about stopping. For me it was about reframing how I engaged and what I prioritised.

Empathetic relationships require you to be present. I removed the word busy from my thinking, I became present, and this presence slowed my mind, allowing me to achieve more and ensure I had the emotional space to empathise.

Trust is vital in meaningful relationships and is being recognised more and more in business as essential.

A recent report by Deloitte highlights the commercial and long-term value of trust by consumers, staff and the community.

Empathetic relationships create a safe space for people to acknowledge when they need help, when they make a mistake or to openly share ideas and innovate. By being empathetic you can use mistakes to engage the person and create an environment for people to learn and grow and to improve the performance of the business.

I want to come back to the notion I raised at the start, of genuine empathetic relationships.

To have effective empathetic relationships you must be genuine. “Fake it ‘til you make it” will never win out in the long run as at some point people will realise that you are not genuine and you are not showing empathy.

Through empathy you can build and develop stronger teams. I love sports and love the concept of doing the one percenters.

Small gains over a season add up to big improvements for the team. I have successfully grown teams using this philosophy. Set the KPIs and support the team to achieve them.

Through trust, empathy and communication the team will themselves lift the bar and achieve more. Empathy is critical. To improve, individuals have to develop confidence in themselves. You cannot force this. It occurs through supporting your people as they realise their potential. I look back and am proud of team members who grew into senior management roles, took on increased responsibility, recognised their talents, gained promotions externally or challenged themselves

to get outside their comfort zone.

I know that individuals will seek to achieve more and get the best out of themselves when they know that praise is genuine, feedback is constructive and they are understood.

I look back on the achievement of some teams I have led with pride. Building teams that were autonomous and high performing.

I saw individuals achieve personal goals. The philosophy I use is to set the bar above where the individual/team think they can reach. To improve individual performance people have to develop confidence in themselves. You cannot force this. It occurs through supporting people to realise their potential. Through trust, empathy and communication the team will themselves lift the bar and achieve more.

As a senior leader, I am accountable for delivering a result. I have signed on for this level of accountability and I am okay with it.

The results I am required to deliver will vary depending on the organisation, but it always has a financial aspect. Be it a profitable return to shareholders, value to members, preserving cashflow or growing revenue. The bottom line is a critical result in any organisation. Financial objectives can often be a source of disconnect, or even conflict, between staff, teams and management. Some of the biggest tests I have faced have been times when the bottom line outcome required hard decisions that impacted people. At times it is my job to make a hard call, but it is how you do it that is important.

When I reflect on some hard decisions, empathy may not be the appropriate term.

Ensuring my decisions considered the impact on people and communicating fully and openly was important.

Now as I edge closer to the golden age of 50, I am just starting to understand this thing called empathy. For me it starts with being honest with myself. I know what I am not good at and what I need support with, and I easily call that out. I believe that to build empathetic relationships you need a level of personal braveness. I am not afraid to say when I disagree. I am not afraid to surround myself with people who are smarter, better at the detail or technical areas and learn from them and I am brave enough to try new things and challenge myself to fail. • EFFECTIVE LEADERS - AVAILABLE NOW

STRIVING TO RAISE

THE VACCINATION RATE Following shutdown orders in NSW and Victoria we are now seeing the resumption of work in the Greater Sydney area and (at the time of writing) shut down restrictions remained in place for Victoria. The states are placing a strong emphasis on vaccine uptake as part of their roadmaps and the construction industry implementing vaccination requirements and sites continuing to maintain and execute COVID-safe plans.

We are seeing numerous businesses and industries respond to the pandemic by encouraging vaccination in various ways. A few initiatives are being implemented to encourage vaccination, eg: • MinterEllison’s goal for 80 per cent of its staff to be fully vaccinated by 1 December.

• Fully vaccinated Qantas Frequent Flyers can gain rewards points or status credits.

• Virgin Airlines is offering prizes and incentives to its customers.

• Medibank is giving away gift cards to members.

• AIA Health Insurance is offering rewards points.

• Telstra is offering staff rewards.

As our industry is being impacted by closures, we are looking to vaccination rates as part of the roadmap and strategy to help get people back to work and help reduce the devastating health impacts of the virus. About six months ago I wrote about the investment in infrastructure

being the backbone of our economic recovery. Closed construction worksites will not lead the recovery, so the industry must get back to work - safely.

I fully appreciate that people ultimately have the right to choose. I chose to be vaccinated and I am encouraging the industry and its employers to help us reach a critical level in vaccinations, ie: • Support your workers to get vaccinated.

• Provide access to information from health authorities that will allow people to make an informed choice.

• Treat masks as PPE. Ensure they are clean, worn properly and people understand how they contribute to minimising the risk of airborne viral transmission.

On a different note, the IQA will be running graduation nights in NSW and Victoria once restrictions lift. These student presentation events acknowledge and celebrate the academic achievements of extractive industry graduates at Certificate III, IV or Diploma level.
