/// OPINION

THE QUARRY INDUSTRY IN NZ: The quarry and recycling industries have always been cyclical, with periods of boom and bust. While it’s easy to get caught up in the challenges of today, the key to enduring success lies in looking ahead and staying focused on the long-term objectives.

Yes, it’s slow out there right now, but just as quickly as the tap turned off, it can turn back on, and will we be ready? Companies that thrive, especially in tough times, are those that demonstrate resilience and are committed to building towards their future goals.

An undeniable truth in the quarry and recycling sectors is the irreplaceable role of aggregates. The demand is heavily driven by the construction market, which remains a cornerstone of the economy. However, simply waiting for the market to improve isn’t enough. To truly survive and thrive, we must focus on what we can influence and make strategic changes today that will position us for long-term success.

Regardless of what’s happening in the industry, we can always make improvements within our own circle of influence.

Creating a continuous improvement culture and mindset drives efficiencies, challenges the status quo and sets us up for when the tide turns. One way we find this working at Equip2, is a daily challenge to come up with a new idea for improvement. As we implement these ideas, it sets a flywheel effect in motion and we quickly see the effects of constant optimization. Incremental improvements like this can make a big difference over time, and encourages the whole team to be on the lookout for innovation and ways to improve business operations.

empower teams to collaborate and think creatively, encouraging innovation at every level of the business. It’s about fostering a mindset that embraces change and seeks better ways of doing things.

The resilience to weather through tough times and the drive to build for the future are what separates companies that grow, from those that fall. When we focus on small daily improvements, continuously strive for greater efficiency, and build a culture of innovation and resilience, we ensure that we’re not only surviving today but positioning ourselves for success in the future.

At Equip2, we want to see New Zealand thriving. We want a strong economy, and in turn, stronger industries, businesses and families that rely on it. Our part to play is in building relationships, providing equipment, advice and support that will reduce costs, increase outputs and maximise performance. If we focus on what we can do, we will be on track to a stronger, more resilient New Zealand. Although it’s challenging, now is the time to stay focused on the long-term goals, embrace resilience, and build for tomorrow—one small step at a time.

Adopting a culture of continuous improvement goes beyond processes and tools. Leadership and company culture are fundamental in fostering this environment. Leaders must

KEESTACK R3 DOUBLE DECK

Quarry owners looking for the next move in crushing technology, meet the Keestrack R3e with double deck— the new player on the team.

The Next Level in Crushing Quarry owners looking for the next move in crushing technology, meet the Keestrack R3e with double deck- the new player on the team.

This machine has been expertly engineered to streamline workflows, reduce carbon footprint, optimize production, and enhance ease of use. It’s not just another impact crusher — it’s a game changer. With double decks, hybrid power options, remote control and enhanced durability, it’s an imperative investment for those serious about performance.

/// CASE STUDY: C & D /// KEESTRACK R3E

Designed by Techs, for Techs Ease of maintenance is a key pillar of the Keestrack philosophy.

Kees Hoogendoorn himself was a fitter - he knows what it’s like to work on these machines and you can tell. Everything is built for ease of access, smooth operation and low maintenance, from the open access engine bay with an auto greaser, to the pressurised housing for the electrics.

Even the little things are expertly engineered. For example, their steel piping that dissipates heat more efficiently than typical rubber hosing, the machine doors which have heavy duty handles and gas struts.

As Bert swings open the side doors, we can see the filters in thought out, logical locations, right where you need them for faster maintenance. Its’ simple, smart design that makes the everyday operations easier.

Everything is built for ease of access, smooth operation, and low maintenance.

Easy On

Bert Hart, Equip2, takes us for a closer look, and we’re impressed from the start. Standing at the control panel the first thing we notice is signature Keestrack simplicity - once the ignition is on, you reset the e-stops and the machine is ready to run.

Like all Keestracks, you can also operate the machine entirely from the remote. Operators can auto-start the machine, adjust feeder speed, main belt speed, and even the crusher entry—all without leaving the cab.

/// CASE STUDY: C & D /// KEESTRACK R3E

Good things come in twos with the R3e— double decks, dual aprons, and hybrid power options.

The Double Advantage Good things come in twos with the R3e, with double decks, dual aprons and your hybrid power options.

The standout feature that puts the R3e leagues above any other machine, is the new double deck screen box. It’s yet another example of thoughtful design that’s unique to the Keestrack.

Making the switch to the Keestrack family with Equip2 provides you with a massive competitive advantage. Ultimately resulting in more profitable Quarry business.. With two decks you can double output by pulling a mid-fraction product and a main product simultaneously, maximizing your efficiency. Each belt has a stacking height of three meters, increasing stockpiling capability and any returns material is sent back into the machine for an extra innings - no wastage, maximum output.

Speaking of double, this plant also has dual aprons which are all interchangeable, reversible and replaceable. Its just another way you can maximise output, reduce maintenance costs and keep the machine operating for longer.

Hybrid Powerhouse

One of the R3e’s biggest advantages is its hybrid power system, giving you options - either run it off the onboard generator, or plug it straight into the mains. It’s one of the first up to the plate in terms of hybrid crushers, delivering a potential 90 percent reduction in carbon footprint. Running electric means you’ll see significant savings and you’ll also lose the engine noise.

No power? No problem. For sites off the beaten track where you don’t have access to the grid, the onboard diesel Genset will still keep you running. And even then, this efficient player still delivers a 50 percent carbon footprint reduction, compared to a traditional diesel - hydraulic plant.

“It’s one of the first up to the plate in terms of hybrid crushers, delivering a potential 90 percent reduction in carbon footprint.”

Crushing It We head inside the chamber for a closer look at the R3e’s game changing square rotor design. The shape of the rotor means less grinding and more impact, as material hits the face of the blowbar, launching it up at a perfect 45 degree angle to the dual aprons. The result? Better shape, higher production, and longer wear life.

Its no secret these machines have to take a few hard knocks, and every aspect of the R3e is built with durability in mind. Starting at the top, the hopper is lined with a Hardox steel, reinforcing the already durable Domex parent material. The whole frame is made of Domex, a 350 grade steel that saves on transport weight without sacrificing strength.

While we’re looking at the hopper, Bert points out the unique asymmetric design, which prevents jams and keeps material flowing.

With production rates reaching up to 400 tonnes per hour and a design that excels in processing everything from limestone to greywacke, the R3e is built for high performance. In the below Walkthrough video, Bert tells us that sites with this machine are reporting a 30% increase in production over traditional set ups - that’s a massive contribution to growth and profitability, in an industry where every load counts.

The Keestrack Difference For Quarry Managers looking for a machine that delivers on efficiency, performance, and ease of use, the Keestrack R3e with a double deck is your star player that consistently gets scores on the board. It’s built by people who understand the game, for people who want results. Keestrack thinks for the Quarry - and that’s what makes these machines stand out.

AN EYE FOR THE BEST:

THE EVOLUTION OF CRAWFORD GRAVEL

“Everybody’s keen to sell you something but they’re not keen to fix it when something goes wrong.

So that’s why we’ve gone with Equip2. The price was good, the back up service is phenomenal and that’s why we’ve gone that way.”

-Graham Crawford

Edendale

White Gold Mining From the outset, things were nothing impressive. “We started off with a small gravel pit over by the duck pond,” says Graham Crawford, pointing across the mounds of pristine white gravel surrounding us. What began as a small-scale farm operation for lane maintenance has transformed into one of the largest concrete aggregate production sites in Southland.

At Crawford Gravel in Edendale, we sat down with Graham to hear the full story—how a simple gravel pit became a major quarry supplying over 200,000 tonnes of top-quality aggregate per year to five concrete plants across Southland and Otago. With strategic investments in land, equipment, and water sustainability, his operation is now poised for even greater expansion, and demand is soaring with new infrastructure projects like wind farms and industrial developments.

For Graham, the key to success has been investing in the right machinery at the right time—and his latest move to the MWS S130 wash plant has completely transformed production, halving diesel costs, slashing maintenance, and doubling output.

/// CRAWFORD GRAVEL

Running a highoutput quarry requires efficient, cost-effective machinery. Graham knew the old equipment was costing too much to maintain.

From a Small Step

Graham has worked this land for over 40 years. When he first bought the farm, there was a small gravel pit at one end, mainly used for local farm lane maintenance. Over time, farmers started coming by to grab small loads of gravel, and Graham saw an opportunity.

He expanded the site, and uncovered vast reserves of highquality white stone. Seeing the potential, he purchased neighboring farms, growing the operation to 325 acres with an estimated 7 million cubic meters of gravel reserves.

The site was initially run by just Graham and one staff member screening gravel on weekends—today, it employs four fulltime workers and contracts out heavy earthworks to a team of articulated dumpers.

“We are sitting on a white goldmine,” Graham says with a smile, standing aside a stockpile of premium aggregate. His operation is now a cornerstone of the region’s construction industry, and demand continues to rise.

With quarry consents secured for 15 years and major projects in the pipeline, Crawford Gravel needed to scale up production fast—which meant investing in smarter, more efficient machinery.

To A Giant Leap

Quick Read: MWS S130

Running a high-output quarry requires efficient, cost-effective machinery. Graham knew the old equipment was costing too much to maintain, so he made the leap to a modern MWS S130 wash plant with a sand screw system—a move that has paid off massively.

Lower Operating Costs: The old system burned $9,000 a day in fuel just to produce 900 tonnes of product. One engine is now doing the job of two, cutting diesel consumption by 50%.

“We looked at other plants” Graeme explains, but the final decision came down to the service from Equip2. “Everybody’s keen to sell you something but they’re not keen to fix it when something goes wrong. So that’s why we’ve gone with Equip2. The price was good, the back up service is phenomenal and that’s why we’ve gone that way.”

costing up to $5,000 a day in maintenance. The new system has had zero major breakdowns.

Dramatically Reduced Maintenance: The old plant was

Higher Production & Efficiency: The site is now producing 1,500 tonnes per day, with plans to scale up further to 1,800 tonnes per day in the coming months.

Cleaner, More Consistent Product:The sand screw setup eliminates unnecessary processing while still producing the exact specifications concrete plants require.

/// CRAWFORD GRAVEL Less is More

Local engineering contractor Nigel McCord has nothing but praise for the build quality and design of the MWS S130.

"For 15 years, I was a registered welding inspector, and I have to say, the construction of this machine is excellent. Very, very impressed with both the design and the actual welding and construction of it" Nigel adds, “This plant is proven to be a very good piece of kit. It does the job that it's supposed to do. And it pretty much did it from day one.” The efficiency of the new plant has streamlined operations to a single person running the feed and output, with a backup only moving stockpiles when needed. One engine, one loader, and one machine now replace two aging plants and a bucket wheel system.

Back to Basics

Beyond productivity and cost savings, Graham is committed to running an environmentally responsible quarry. His innovative water recycling system is a fundamental part of the operation - “We do not use any spare water, it’s all recycled” Graeme proudly tells us. The site’s spring-fed duck pond he showed us earlier serves as a natural, self-sustaining water source for the wash plant.

After passing through the plant, dirty water flows into a series of sediment catchments, where it is naturally filtered before returning to the main pond.

Its a closed-loop system, meaning Graeme isn’t relying on costly water use permits. Its good for Graeme, and good for the environment. In fact, his set up has so impressed local councils that Environment Southland want to showcase it as a model for sustainable water systems. The pond isn’t the only part of the original farm that remains - the site is surrounded by rehabilitated dairy paddocks. Graeme ensures that once a site is finished with, clean fill from excavation work is used to restore the area, seamlessly blending them back into grazing land. Its just another way Graeme has his eye on whats best - for him, for the environment and for the economy.
