CONVEYOR MANUFACTURERS ASSOCIATION

From The Chairman’s Desk As mentioned in the January article, the four issues that are affecting industry are of primary focus at the moment and the work being done will prove to be a huge advantage to industry. These are Nip Guards, Pull Keys, Directional Rollers and testing of Flame Retardant Belting.

In setting up the Working Group to address Nip Guards and Pull Keys, the buy-in from industry is demonstrated by the fact that end-users have seconded some of their most experienced and senior personnel to the Working Group. End-users include Anglo Platinum, Anglo Coal, Sasol, Lonmin and Aquarius.

CMA member companies (Cedotech, Flexco, ThyssenKrupp, and Afripp) have similarly responded by supplying their expertise, making this probably one of the most experienced working groups that can be assembled for addressing the issues at hand.

Specifically, these are the nip guard and pull key

issues. The group is chaired by one of our honorary members, Alan Exton.

Of similar importance is the Group established to review the issues pertaining to uni-directional rollers.

The idler manufacturers have been approached to make their brains trust available to the Working Group. Once the work has been completed, the Nip Guard and Pull Keys Working Group will have sight of the recommendations for finalisation. To complete the process, Industry will receive all outcomes from the two Working Groups at an Industry Indaba which will be scheduled for later this year.

B-BBEE COMPLIANCE

Taking the Sweat Out of Procurement With the changeover to the new B-BBEE codes for all certificates issued from 1 May 2015, LexisNexis South Africa has added a B-BBEE compliance module to ProcureCheck.

A

s companies develop plans to meet the stringent requirements of the amended codes, the new edition puts all the intelligence required for conducting procurement business professionally and ethically on one platform, facilitating the entire vendor management function.

“The new B-BBEE legislation is changing

the way in which a company’s vendor database must comply with BEE codes and standards. Whereas previously only vendors pertaining to 80% of procurement spend had to be BEE compliant, now 80% of the vendor database needs to be compliant and to meet the new quotas. This means more SMEs and EMEs will need to be vetted for companies to comply,” says Greg Brown of Nexis.

Verification

ProcureCheck with B-BBEE Compliance is designed to reduce the cost of compliance, fulfil regulatory requirements, enhance decision-making and protect businesses from fraud and reputational damage.

This innovative solution adds the ability to manage B-BBEE compliance including: monitoring the expiry date of your certificate, monitoring your procurement spend, monitoring your suppliers’ progress in terms of B-BBEE to the other capabilities of Procurecheck.

"In addition it will help you identify Enterprise Development/Supplier Development opportunities to increase

B-BBEE COMPLIANCE

While the system will expose public sector officials, it will also put pressure on companies looking to win government business to comply, to constantly monitor and improve their B-BBEE status, as well as to meet all the requirements of the Public Finance and Municipal Finance Management Acts your scores in this area of the B-BBEE scorecard,” Greg adds.

He urges companies to start planning for their next verification on the amended codes, warning that insufficient planning could result in organisations being downgraded. He also highlights that the new edition ProcureCheck is being launched at a time when procurement fraud and corruption have been widely publicised and strict reforms are being introduced.

Central supplier database

In February 2015 Finance Minister, Nhlanhla Nene announced in his budget speech that from April 2015, a central supplier database would be introduced.

The database will interface with South African Revenue Services (SARS), the Companies and Intellectual Property Commission and the payroll system.

It will electronically verify a supplier's tax and BEE status, and enable public sector officials doing business with the state to be identified.

“While the system will expose public sector officials, it will also put pressure on companies looking to win government business to comply, to constantly monitor and improve their B-BBEE status, as well as to meet all the requirements of the Public Finance and Municipal Finance Management Acts,” Greg advises.

ProcureCheck links to various data bases including the Companies and Intellectual Property Commission (CIPC), South African Fraud Protection Services (SAFPS), SARS, Value Added Tax (VAT), Judgements and the National Treasury

Restricted Database. It enables supply chain staff to access the information they need anytime, anywhere, to: Combat corruption by identifying potential connections and ownership of property Identify possible fraudulent activity within vendors and employees with the help of South African Fraud Prevention Services and automated or online procurement management systems Establish the business interests of employees within your organisation Look for and recognise conflicts of interest within your organisation and potential supply chain management partners Vet vendors and create a preferred vendor list Monitor vendors on an ongoing basis.

Accountable “Under King III, the CEO of a company can be held accountable for any theft, fraud, corruption and bribery taking place in his business under his watch and should therefore take procurement vetting seriously.

Used effectively Procurecheck with B-BBEE Compliance enables users to turn compliance into competitive advantage,” Greg concludes.

Gautrain Station The Gautrain Station platforms at OR Tambo International Airport are to be expanded, enabling passengers to embark or disembark from a full four-car train set, which is currently limited to two cars.

T

urner & Townsend has been appointed by Bombela Concession Company to manage this prestigious turnkey expansion project. The duration of the construction project is approximately 12 months with anticipated completion by mid-2016.

Noluthando Molao, associate director of Turner & Townsend, says construction itself will be carried out with pre-cast elements and with the establishment of a storage area for materials close by, in order to minimise activity on site. An interesting aspect of the project is that the tower crane to be used on site is one of the biggest in the country, which can lift 32 tons at a radius of 27.8m and can pick up a maximum load of 20.6 tons at a radius of 40m.

Initially procured for the Medupi Power Station, the crane will be relocated to the OR Tambo construction site.

“One of the key challenges of the project is that the trains must be fully operational at all times to ensure there is no disruption to the Gautrain service. Coupled with this, the construction is being carried out at approximately 18 metres above ground level, with the access road directly beneath the construction site needing to remain operational as an airport entry point. What makes the construction more challenging is that the crane can only operate from one side of the viaduct structure and safety will be a key priority.

The access road directly beneath the construction site needing to remain operational as an airport entry point “Furthermore, the close proximity of the City Lodge parking facility right next to the construction site presents another challenge. Noise and

dust will be minimised with most of the work being completed off site and the use of acoustic boards, while construction will only be undertaken during specific times as agreed,” says Noluthando.

“Given the issue of cable theft, the safety and security management systems require that the highest security measures are in place at all times.”

They also provided procurement advice and training to the building and civil contractor.

increasing either side of the platform as well as extending the platform length by a total of 55 metres. In addition, the concrete parapet wall will be extended and two fire escape towers constructed.

Adds Noluthando, “Not surprisingly, the contractor tender process had a technical requirement for a grading of nine, which is the highest level according to the Construction Industry Development Board. A BEE Level 3 minimum requirement was also stipulated and the successful contractor, Stefanutti Stocks, will have to achieve 80 percent of the scorecard for technical criteria.”

Globally, and with a network of 90 offices, Turner & Townsend has an extensive track record in major projects, and more specifically in the air sector having helped formulate and implement the agreement for the build of British Airways Terminal 5 at Heathrow Airport (the biggest free-standing structure in the UK) and playing an integral role in bringing the project in on time and on budget.

Turner & Townsend has also been involved in providing master planning, procurement strategy and risk management services for the development of the new three-runway system at Hong Kong International Airport and delivering cost estimating services, scheduling and risk management for the expansion of Abu Dhabi International Airport.

Conserving Marine Life A jib crane installed on a small island off the South African coast is rendering sterling service to ornithological teams visiting and conserving marine bird colonies which nest and breed there.

Installed with a motorised 360-degree slew on Bird Island, eight kilometres offshore from Woody Cape and 62 kilometres from Port Elizabeth, the Condra crane has been used since 2010 to lift the scientists’ boat from the sea onto a trailer, which is then winched along the jetty into a boathouse for the duration of the visit.

The scientific visits are important for the study and restoration of the island’s marine bird colonies.

Success stories include the revival of the island’s population of African penguins from fewer than 100 pairs 75 years ago to well over 10 000 birds today Protected by South African National Parks as part of the Addo Elephant National Park, Bird Island and several smaller rocky outcrops form important habitats for bird life. The 2,4 hectares of Bird Island itself are home to South Africa’s greatest colonies of Cape gannets (65 000 breeding pairs), African penguins, endangered roseate terns (just 250 breeding pairs), Antarctic terns and kelp gulls.

Success stories include the revival of the island’s population of African penguins from fewer than 100 pairs 75 years ago to well over 10 000 birds today, the result of the cessation of guano scraping and the extermination of feral rabbits.

Scientific teams To meet the requirements of the visiting scientific teams, H&M Cranes of Port Elizabeth supplied a Condra jib crane with a 360-degree slew and reach of 4,5 metres, fitted with a single-speed 2,5-ton chain hoist with a 7,5 metre lift. H&M Cranes is the Port Elizabeth agent for Condra products.

Although the jib crane came from Condra’s standard range, its components had to be designed in four sections each having a mass under 800 kilogrammes, to allow transport and installation on the island by helicopter.

An Alouette helicopter hired by National Parks was used to ferry the crane components to the island in three trips, with a fourth journey being made to bring in the jib.

The lower two sections of the column were mounted on the foundation plinth of an underwater concrete foundation, bolted together and encased with concrete. The top column section, jib and motor were then installed with the aid of the Alouette, which precisely positioned the motor for fitting and attaching.

Lead time

Gauteng-based Condra offers a range of standard jib cranes with capacities of up to 5 tons and reaches up to 7 metres. These standard designs provide the company with a competitive advantage when short lead times are specified, because most South African crane manufacturers lack a standard range.

Condra has also supplied custom designed jib cranes with reaches up to 12 metres. The company is currently manufacturing a standard 5-ton jib crane for Grootegeluk coal mine in Lephalale.

At the forefront of materials handling systems

“

The speed at which a tower crane can lift and place loads is directly linked to the productivity that a site will be able to achieve on any given day,” says David Semple, Manitowoc VP Sales Middle East & Africa. “Fast track projects have become the standard throughout the world today and being able to build rapidly is a major benefit to any contractor.

“There is a significant difference in the speed at which construction can take place based on the amount of materials moved in a single working day. For example, whether you can pour 100 buckets of concrete or 120 buckets can have an impact on the daily build programme,” he adds.

Accessibility to materials

In addition to operational productivity, the speed of erection and disassembly of the tower crane is just as important.

This also receives attention during engineering as the speed at which the tower crane is erected will dictate the site’s accessibility to materials. Furthermore, the speed at which the unit can be climbed also has an impact, especially where the building being constructed is high rise.

“An example where advanced engineering has made a difference is in the tying of the Potain tower crane into a high rise building as it climbs. This can be done in 6 hours as opposed to the conventionally accepted 8 hours with other similar cranes,” David says.

Dismantling of the machine is also important as this too is a time-related task. The Potain tower crane has been engineered to facilitate speed of erection as well as dismantling, and its ergonomic design makes it easier for rigging crews and ensures optimal safety during both activities.

people

Productivity of a tower crane could also be compromised if it is not correctly configured as it would then not operate optimally. An example could be where the winch is undersized and the tower crane could then become a bottleneck on site, slowing down materials handling and subsequent construction activities.

LIFTING

Partner with a reputable supplier

Torre Lifting Solutions, SA French division, is the southern African distributor for Potain tower cranes and Quentin van Breda, technical director says that it is important that contractors partner with a reputable equipment supplier who has the depth of technical skill to appropriately configure a tower crane for a specific application.

“Tower cranes should be constructed to maximise productivity without breaching operational performance or safety protocols,” he says. “And this requires the input of experienced people who understand both the technical ability of the crane as well as the actual site requirements.”

Potain tower cranes are recognised for their failproof design and excellent lifespan.

Components test Manitowoc operates a Product Verification Centre (PVC) in France where all major components are

Advances in Flame Retardant Belting and the Future Flame retardant belting has been in general use for decades since this stipulation was enforced by the National Coal Board (NCB) when conveyors in industrial coal mining were first used.

T

his article highlights several improvements that have emerged in flame retardant belting over the past few years, and also comments on likely future developments.

History of flame retardant belting

There is a pronounced difference between ’Flame Resistant’ and ’Flame Retardant’ belting. Flame resistant implies that the object will not burn, whereas flame retardant implies that the object can burn but will retard the flame propagation.

First Generation Belts (1905)

The first generation belts were manufactured from cotton carcasses soaked with PVC paste. During the burning process of polyvinyl chlorine (PVC) belting, chlorine gas is emitted which starves the flames of oxygen preventing further burning and thus the belt automatically self-extinguishes.

tions. The flame retardant properties were still obtained through the use of PVC as the saturate.

Unfortunately PVC also releases highly toxic fumes in large quantities coupled with high smoke densities. Examples of the toxic gases are NO, CO, CO2, HCl and SO2 There are still, however, many mines that use this type of belting, mainly due to the low associated cost.

Third Generation Belts (1980)

Multi-ply rubber covered belts were developed and introduced in the 1980s. The rubber contained high levels of chlorinated paraffin that was used to starve the fire of oxygen. These belts also released highly toxic fumes in large quantities associated with high smoke densities.

The toxicity index is calculated from the summation of the ratios of these concentrations to the concentrations causing fatality to an individual after a 30- minute exposure time. Gases and their fatality limits, as defined in UK Naval Engineering Standard NES 713, are shown in Table 2.

Fourth Generation Belts (1992)

The introduction of the ‘Gallery Test’ forced manu-

facturers to increase the flame resistance of belts.

The Gallery Test simulates a belt burning underground in a confined space with an air draft. This is a fairly severe test and generation one to three belts did not comply. As a consequence, belt manufacturers reduced the potential fuel sources usually added to the rubber, and also examined the type of rubber used. This resulted in an increase in the belt cost but a much safer belt.

Unfortunately, highly toxic fumes and high smoke density remained a problem. Earlier versions of flame retardant belting specifications focused purely on the self-extinguishing properties of the belt and not the toxicity levels or smoke density generated by a burning belt.

Fifth Generation Belts Most of the rubber belts currently supplied, excluding PVC belts, incorporate non-halogenated products to achieve the required self-extinguishing properties. Basically, a mixture of chemicals is added to the rubber, which during the combustion process, release water which extinguishes the fire. Chlorine was thus eliminated from the rubber formulation and toxicity reduced.

Figure 4. The smoke density levels have reduced dramatically

These modifications were still, regrettably, insufficient in lowering the remaining high levels of toxic fumes coupled with high smoke density during combustion.

The latest generation of fire retardant belting

To date, the focus of all the conveyor belt specifications have been on the ’flame’. There are no regulations or guidelines for the smoke density or gas toxic levels.

The belt evaluation laboratory test (B.E.L.T.) also known as the ’Gallery Test’ does not measure or control the smoke properties.

Conveyor belt manufacturers have now developed flame retardant belting with a much lower toxicity and also drastically reduced smoke density. Figures 2 - 4 illustrate the reduction in the toxic gas levels and also the improved drop in smoke density.

Conclusion

Generation two, three, four and five belts are all currently used in South Africa. All of the above complied with the requirements of SANS 971 up until the latest revision of 2013 where changes were introduced to reduce the belt flame propagation properties in line with the best global specifications.

Without sacrificing on belt performance, the latest generation of flame retardant belts will ensure a much safer environment compared to older generation belts. The major reduction in toxic gas levels coupled with the improved drop in optical density will most definitely result in a safer environment in the event of a fire starting.

PORTS

The ports industry is in a state of radical change and uncertainty, which requires flexible and adaptable port planning and design. This is according to Phyllis Difeto, Transnet National Ports Authority’s (TNPA) Chief Operations Officer.

“

The impact of the global economic downturn is a daily reminder to ports of the need to change ‘business as usual’. Innovative techniques are required to adapt to the pressures of integrating the global supply chain, the need for greater

port expansion and the immediate requirement to preserve natural resources,” she says.

Phyllis outlines the South African port authority’s strategic direction and key projects from 2015 to 2022. Transnet’s Market Demand Strategy – which aims to enable the effective, efficient and economic functioning of an integrated port system to promote economic growth – is in its third year of implementation. Transnet has invested R92.8bn to date, of which port investments amount to R5.78bn. TNPA’s investment in the South African port system over the next 10 years will be R 56bn, of which R320m will be spent in the 2015/16 financial year.

“The South African government’s focus on the Oceans Economy under its Operation Phakisa initiative will be a major driver to invest in the port system. A total of around R2bn will be spent over the next five years to refurbish existing repair facilities, while we will invest an estimated R13 to 15bn to create new repair facilities at the South African ports,” she adds.

Phyllis adds, “We have made solid progress. We have digitised our eight ports through our Integrated Port Management System (IPMS), and are monitoring port efficiencies while implementing performance operating standards for all operations – at the terminal, marine, haulier / road and rail interfaces. We are also in the process of establishing Joint Operations Centres (JOC) across the port system.

Complement rather than compete

“Within the parameters of our economic regulatory environment we are striving to improve the sustainability of the port system. Transformation of the port system is another priority and all new port projects, contracts and leases are subject to strict transformation criteria. We are developing our suppliers and trying to ensure that the ports provide opportunities to local suppliers and the previously disadvantaged,” she emphasises.

TNPA’s port framework plans are reviewed annually and adjusted to suit the economic, policy, trade and technology environment. The port plans allowed TNPA to manage land use and optimise its investments.

TNPA is landlord of eight commercial ports around the South African coastline. Transnet’s integrated system of regional ports and rail corridors aim to complement rather than compete with each other, Phyllis concludes.

A Happy and Productive Operator

The latest backhoe loaders are all about the operator, Desigen Naicker, Building Construction Products marketing manager for Barloworld Equipment Southern Africa, tells “Bulk Handling Today”.

H

aving produced more than 300 000 of these machines that are working globally, the latest generation F2 series is improved and impressive. While doing more work faster forms a big part of the new offering, the machine is setting industry standards for operator comfort. Desigen tells us, “While the leader is far more modern- looking, essentially it was designed with the operator in mind with improved controls, enhanced visibility and just all round better comfort. Let’s face it – a happy operator is a productive operator.”

We are adamant that we will not just replicate Western solutions The machine is the product of ongoing collaboration and partnering with customers to tailor-make a backhoe loader that best suits their needs. “New designs no longer take place in a vacuum. We make a point of consulting with our customers to get a close up and personal account of what they would like to see in new generation equipment,” Desigen comments.

“The North American landscape where Caterpillar has a large presence is very different from Africa and so it’s an ongoing process to deliver to local customers machines that have been refined to address the unique aspects of working in Africa.

“This is a key driver for us and we are adamant that we will not just replicate Western solutions.”

Pioneering success

The first Cat backhoe was produced in 1985 in Leicester, England at a manufacturing plant for the assembly of forklift trucks. Since its inception the

machine with its distinct and unique features has been an industry success.

The introductory units of the A series were immediately recognisable by the distinctive curved boom design, narrow loader tower and divergent loader arms. These lift arms remain unique to Cat loaders to this day. The same goes for the curved boom design that is also an industry exclusive.

Launched with an operating weigh of approximately 6 087kg and a lift capacity at full height of 2 381kg, the machine has seen some major technological advancement over time such as the industry’s first true excavator style boom. Then there’s the industry exclusive 205 degree rotation bucket linkage while overall durability has been enhanced with improved hydraulic and electrical components.

The improved F series

First introduced in 2012, the F Series has continued this development tradition resulting in the latest range of machines – the F2’s. “We are seeing exceptional performance versatility and jobsite efficiency,” says Desigen. “They are also operating across sectors where due to their versatility they are proving their worth. One machine can do a lot on a site.”

The F2 has an upgraded hydraulics system that provides improvements in oil flow for optimum delivery: the 422F2 from 125litres per minute to 132l/min; the 428F2 and 434F2 from 125l/min to 160l/min; and the 432F2 and 444F2 from 156l/ min to 163l/min. All machines feature Cat’s proprietary load-sensing hydraulics where the variable flow system senses the work demand and adjusts the flow and pressure to match.

“Essentially what this means is the achievement of high bucket dig forces whatever the engine speed, providing excellent control, while reducing fuel consumption,” explains Desigen. “Machines sold into Southern Africa also come equipped with new generation four-speed manual transmission in forward and reverse with the top speed at around 40km/h.”

of machines, is maintenance. “Planned maintenance is obviously far more cost effective as there is less downtime. Our VisionLink offering allows an owner to view machine vitals and machine hours online via a computer or even mobile phone allowing for preventative maintenance planning,” Desigen advises.

Three lives

Owners are catered for through a diverse range of products. “Whether it’s a major corporation or a small enterprise, we are geared to service the entire spectrum,” he adds. From buying a new machine, a Cat Certified Used or even just renting via the Cat Rental Store, Desigen maintains the company is opened to finding the right solution for each and every customer.

In line with customer requests for more safety features, the redesigned cab (except for the curved front window) now has flat glass doors and windows.

With the right parts, machines can easily be given second or even third lives Optional pilot controls provide low effort operation with the ability to switch between excavator and backhoe control patterns with the simple press of a button.

“There have also been some changes to the aesthetic controls. The decibel level in the cab is improved significantly offering a much safer and quieter cab for operators. Another important focus for us is the aftersales component. Cat machines are designed with more than one life in mind. With the right parts, machines can easily be given second or even third lives.”

“We also offer a variety of financing package solutions and Cat work tool solutions are available for large or small companies with the focus on making it as affordable and versatile to own or rent our equipment. Ultimately – be it the design of the machine and its abilities, the purchase or renting process or the maintenance of the equipment – it’s all about making a less complicated environment for owners and operators,” Desigen concludes.

WHISTLE BLOWERS

Get-rich-quick Scheme Whistle Blowers, South Africa’s largest independent whistle blowing service provider, is receiving a growing number of calls from companies seeking advice on the pro's and con's of offering rewards for information that leads to a fraud conviction.

Dale Horne

A

worried Dale Horne, who heads up the operation, believes this is because of publicity surrounding massive pay-outs running into hundreds of millions of dollars in America where it is encouraged.

Ultimately, the aim should be to create a culture of honesty within an organisation Bradley Birkenfeld, an ex-banker who reported his bosses at UBS for helping US clients to hide money in Swiss accounts received $104 million and Cheryl Eckard, a former employee of drugmaker Glaxo Smith Kline, who alleged that there were manufacturing faults at one of the company’s plants, collected $96 million.

A group of employees at Pfizer netted $102 million in September 2009 for exposing the illegal promotion of the arthritis drug Bextra while Kyle Lagow

pocketed $14.5 million for providing information about alleged underwriting and mortgage fraud at a Bank of America subsidiary.

But Dale says that local companies considering going this route, albeit on a far smaller scale, need to think carefully about the potential consequences for both themselves and their employees.

Wrongdoing

He explains that America’s much-debated Dodd-Frank Act, which targets corruption in the financial industry in particular, contains a whistle blowing clause that enables the Securities and Exchange Commission to pay out a reward equivalent to between 10% and 30% of the money recovered should it obtain a conviction with sanctions exceeding $1 million.

Dale believes that whistleblowing is the best and most effective means of rooting out wrongdoing in the corporate domain – a fact underscored by the 2014 Report to the Nations on Occupational Fraud and Abuse carried out by the Association of Certified Fraud Examiners (ACFE).

Based on 34 615 cases spread across America, Europe, Asia, Canada, Latin America, the Middle East and Africa (including South Africa) from October 2013 to December 2013, this report indicated that over 42 percent of all cases were the result of a tip. But fewer than 11 percent of companies provided rewards for whistle blowers.

However, Dale doubts whether rewards contribute significantly towards these figures.

The crux is that companies need to closely examine the motives of those reporting wrong-doing in exchange for cash. There is always the chance of a get-rich-quick scheme that could backfire, he warns.

Dishonesty

“The company intending to pay rewards must consider elements such as how the informer would communicate the information, who would the information be communicated to, how is protection guaranteed, how is the value of the reward

determined, the grounds on which rewards will be paid out, how the rewards would be paid, for example, because it could take some years before a particular matter is finalised?

We believe that companies need to focus on protection of identities rather than on providing rewards Should a company satisfactorily answer these questions, then this should be operated separately from any official whistle-blowing facility.

Dale says that Whistle Blowers does not pay for information. He warns that any investigations that include information for reward should be handled by a registered investigation body, totally independently of the whistle-blowing programme.

The good news, according to Dale is that most people who do blow the whistle on corruption

don’t do so for a reward. The AFI study noted that at any company: 25 percent of employees are dishonest, 25 percent are honest, and the remaining 50 percent could go either way depending on the culture of the organisation.

Therefore Whistle Blowers concentrates on the aspects of ethics and bringing the majority into the crime-fighting fold. “Our experience shows that people don’t come forward to give information for money generally but because it’s the right thing to do.

Ultimately, the aim should be to create a culture of honesty within an organisation. We encourage an ethical solution to a problem where employees speak up in order to protect their employment and their companies,” Dale says.

Protection

Trust rather than money, he emphasises, is actually the chief determinant of whether an employee will blow the whistle.

“We have systems in place to protect a whistle blower’s identity.

Our primary focus is to provide absolute security so whistle blowers keep coming back and don’t fear reprisals. We believe that companies need to focus on protection of identities rather than on providing rewards.”

Dale cautions that there is no formal legislation in South Africa that protects the identity of someone providing information for a reward. Instead, legislation such as the Protected Disclosures Act only provides for legal protection of whistle-blowers provided that a disclosure is made in good faith. If a whistle blower accepts a reward, he or she waives the right to protection with potentially serious consequences.

steel components to prevent bending of the main frame. The extremely durable construction helps eliminate carryback, reduce emergency outages and minimise unscheduled downtime. In some applications, it has been shown to be the only design that can withstand the severe operating conditions.

“This design allows conveyor operators to improve maintenance planning and reduce expenses,” observes product engineer, Daniel Marshall. “With lower maintenance requirements, it saves money through fewer repairs and blade replacements, as well as faster service procedures. The reduced carryback means improved working conditions and plant safety, maximised equipment life and reduced cleanup.”

“The SHD Series was originally designed for a severe-duty mining application, built to handle the overburden at one of the largest pit mines in the world,” Daniel continues. “Every cleaner they tried was getting destroyed by the harsh conditions. There just wasn’t anything on the market that could withstand the speed and abrasive forces, so we completely reengineered the conventional belt cleaner design, from the I-beam frame to the huge blade segments. In fact, these cleaners are so large that we had to invent a way to properly tension them,” he concludes.

Long Haul Cover The transport and logistics business demands unique insurance cover that addresses every aspect of freight and transport risk. MiWay cover is designed to give peace of mind to both short and long haul transport operators across multiple risk areas.

Mornè Stoltz, MiWay Head of Business Insurance, explains that MiWay offers standard and perils based cover, but

always recommends full comprehensive cover to ensure all possible risks are covered. He notes that it is essential to cover the transport company’s assets, loss or damage to third parties’ goods, and have sufficient liability limits.

“Many vehicles spend a large part of the day travelling, increasing the risk of an incident happening. By keeping to dedicated routes on a fixed time-

table, it makes vehicles prime targets.

Vehicle claims are the most frequent, while goods in transit claims can be the most expensive. Often vehicles are found abandoned following a theft or hijacking with the items the vehicle was carrying having been stolen. Our business vehicle product is supported by a goods in transit policy to address these risks,” he says.

Mornè notes that liability insurance should not be overlooked either. “This covers the insured for injuries and/or loss to third parties where the insured can be held legally liable in the case of negligence.”

Full steam ahead Advisian, the advisory business line of WorleyParsons, is rapidly becoming a leading provider of rail advisory and engineering services in Africa, offering independent management and strategic advisory services for the railway sector.

Advisian’s rail practice deals primarily in resource-based rail, focusing on freight and bulk transport. The company is currently involved in a number of rail projects in sub-Saharan Africa that are in various front-end planning stages.

Advisian’s Sub Sahara Africa Managing Principal for Transport Consulting, John Marshall, says that rail transport is increasingly becoming the option of choice in many African countries, where poor infrastructure and road systems hinder the capacity of contractors to deliver goods and services. “The challenge in sub-Saharan Africa is that there is simply insufficient infrastructure, and this is why rail is more frequently being considered as a feasible means of transport,” says John. “Although road transport may be cheaper in the short term, in many cases rail is the more viable option over the long run.”

Advisian is able to provide an integrated service capability for the rail sector including feasibility studies, project management, engineering support and EPCM for new rail corridors, renewal of colonial railways, complex urban rail and integrated rail systems, as well as related services.

Global improvement in 2016 Global sales of construction equipment are forecast to grow 3.9 percent in unit terms in 2016, to 760 508 machines, according to specialist economic forecasting and market research consultant, Off-Highway Research.

The expected improvement follows a weak performance in 2015, when global unit sales fell more than 10 percent from the total of nearly 818 000 machines sold in 2014. In 2016, growth is expected in the European, North American and Indian equipment markets.

“There can be no doubt that 2015 was a tough year for the global equipment industry, due to slowing world economic growth and weak commodity prices,” says Off-Highway Research managing

director David Phillips. “Unit sales fell to their lowest since the crisis years and the drop in the Chinese market was particularly brutal. However, there were improvements in several developed countries which helped offset some of these losses.”

David adds, “The company’s forecast is for the start of a gradual return to health in the global construction equipment market in 2016. However, as has been the case since the crisis years of 2008 and 2009, business confidence remains fragile, and the uncertain geopolitical outlook around the world could have a negative impact on the sector.”

It is designed for handling loads of from 125 to 2000kg. Eurosystem Alu sets itself apart by the lightness of its aluminium hollow sections with a rolling coefficient enabling effortless travelling trolley positioning.

The lightness of the sections enable the VGPA portal frame to be installed and handled by one person. Its weight is now half that of equivalent conventional steel structures. The lightness of the rails also offers the user easy, relatively effortless manipulation even with heavy, unwieldy loads.

With its fully modular design, VGPA portal frames are fitted with folding legs and their height can be adjusted from 1550 to 4000mm. They are mounted on white polyamide hinged wheels for inside use. The portal frame is fully mobile under load.

Maximised Uptime Several key issues can affect the life cycle and productivity of a screen and have an impact on the bottom line at minerals processing operations. These include the shortage of skills within the industry, which often results in sub-standard maintenance being performed. In addition, maintenance is often undertaken on a reactive rather than a proactive basis, which can lead to further costly issues.

“Significantly, Joest Kwatani engineers aim for maximised tonnage of the screen during its lifetime. However, since screens are such critical elements in the process it is important to undertake regimented maintenance to ensure ongoing efficient operation and improved yield,” says Theresa Walton, general manager, service at Joest Kwatani.

These issues are best addressed by the implementation of a service level agreement that is customised for individual mine requirements. The first step is to

Test Laboratory Flexicon has completed construction of an all-new test laboratory for Flexi-Disc tubular cable conveyors and integrated bulk handling equipment.

The laboratory is centred around separate 10 and 15 cm diameter tubular cable conveyor circuits with drive systems and tensioners which can be demonstrated as stand-alone systems. Both circuits are also configured with metered and non-metered inlet adapters, and valved and full-flow discharges that allow for rapid connection to a variety of full size upstream and downstream bulk handling equipment also produced by the company.

Using customer supplied bulk materials, engineers and laboratory technicians verify system performance prior to final equipment design and fabrication, and demonstrate newly constructed equipment for visiting customers prior to shipment. In addition, Flexicon engi-

neers utilise the laboratory to study the performance of new designs.

Expanding upward According to the United Nations, by 2030, almost 5 billion people, or 60 percent of the world’s population will live in cities.

In the context of mega-cities, expansion is no longer outward, it’s upward.

Brett Fleming, CEO of Eazi Group, Africa’s market leader in work-at-height solutions comments, “This industrial growth underpins the need for a shift in the trend of work-at-height solutions, where safety, efficiency and cost are key.”

Recently, Eazi Access Rental landed southern Africa’s first JLG 1850 telescopic boom lift that reaches 58.5 metres in height, in layman’s terms that equates to 17 storeys. This colossus is the shape of things to come and reflects the rising volume of projects and tasks being performed at height.

Eazi Access Rental has seen the need for smaller nimbler cranes, like the Maeda Mini Crane. With the expansion trend being upwards, space becomes increasingly constricted, which is where this mini crane has no equal.

New Appointment

Another major trend is the demand for increasingly environmentally friendly machines that reduce the risk for hydraulic spills and run on electric supply or low-emission diesel engines.

“While traditional work-at-height solutions still remain relevant in many industries,

powered access machines and mobile elevated work platforms should be considered as the modern alternative, being more than just a trend, they offer the latest technology with safety, flexibility and efficiency in mind,” Brett concludes.
