Carrying the load

Liebherr’s powerful materials handlers and wheel loader models have helped recover construction and demolition waste.  

In the harsh terrain of the construction and demolition (C&D) waste sector, a reliable product is needed to sort and move a variety of potentially contaminated materials.

Within South Australia’s capital Adelaide, there are businesses working tirelessly to service the growing body of C&D waste and prevent it from ending up in landfill.

While estimations by Green Industries SA have noted C&D waste contributes to about 33 per cent of the state’s landfill waste, the Adelaide Resource Recovery centre has spent millions in a bid to help reduce this figure.

Based north of Adelaide in the suburb of Dry Creek, the company recycles a variety of C&D streams, including concrete, soil, bricks, processed timbers and plastics.

It receives the materials from building sites, sorts them to prevent contamination, and turns them into valuable products that can be reused within the state’s booming construction industry.

Henry Brzezinski, Adelaide Resource Recovery Site Supervisor in Concrete, says equipment manufacturer Liebherr provided him a cost-effective and reliable product to help his team separate and recycle C&D waste.

Henry says the site on average handles between 800 to 1200 tonnes of materials each day from the building sector, from more than 200 trucks. The team use Liebherr’s LH 22 and 24 Material Handlers to help sort the materials at the facility’s C&D recycling shed, while he supervises the L 586 XPower Wheel Loader at the concrete recycling division, which loads the finished product onto the truck for resale.

“It can be a pretty harsh environment at the recycling shed with a vast amount of dust building up from the materials. The materials handlers take on this really well with both fuel efficiency and comfort,” Henry says.

“There’s more control with these materials handlers – particularly since these machines are on wheels and not tracked. Liebherr really seems to suit what we do for a living.

“Their machines perform all the tasks we need and they it do it well. The materials handler picks up anything from fences to corrugated iron roofing, timber and green waste.”

Liebherr’s Material Handlers use the latest engine and hydraulics technology to improve fuel efficiency while ensuring superior performance.

Both models were designed specifically for use in waste and scrap recycling. The company says it has increased the engine output compared to previous models, boosting cycle times which improve productivity and reduce servicing costs.

Greater fuel efficiency is achieved through a standard automatic idling function, which lowers the engine speed to idle as soon as the operator takes his hand from the joystick, ensuring no hydraulic function is activated.

The modern cab design incorporates a touch screen display, with controls and operator’s seat coordinated to form an ergonomic unit.

“The cab lifts so you can actually look inside the trucks we are loading, allowing the operator to identify if there are any complications with the handling of material we are loading,” Henry adds.

Elsewhere, in the concrete division, Henry says he oversees the operation of the L 586 XPower Wheel Loader, loading recycled road base, ballast and aggregate in an efficient manner.

He says the bucket capacity of 6.0m³ allows more materials to be moved than the previous loader the company was using.

“Compared with the older machine that we had, the L 586 XPower saves a lot of time and fuel.

“The previous one used to handle between four to five buckets in order to load a semi-trailer, whereas the new one can load more materials using only two to three buckets depending on the material density. Because it’s a bigger bucket, it takes less time to fill the same quantities,” Henry explains.

“We have trucks arriving to be loaded  that are rated at a 24-tonne capacity.  With the new XPower wheel loader, we are loading more trucks over the course of the day than ever before.

“The fuel economy is also definitely the best I’ve seen in a wheel loader in a long time.”
