TWO Rokbak RA40 haulers are assisting Atlas Quarries’ operations in New Zealand – 11,000 miles from where they were built in Motherwell.
Supplied by Porter Group, the machines have been put to work at Atlas’ Brynderwyn site, some 100km north of Auckland. Rokbak said the steep site is known for its ‘rugged’ terrain and challenging working conditions.
“Where we haul and fill out to is pretty steep, so with a full load onboard you need to know the truck is going to stop where you want it to,” explained Brynderwyn quarry manager Tony Turnbull. “It’s one thing to scramble up a hill without any worries, but when you’re at the wheel, you also want to know the machine will remain predictable and maintain traction on the way down too.
“In investing in the Rokbak haulers we were also looking for a big improvement in reliability and safety. The trucks are well designed for servicing and all the main checkpoints are at ground level.”
Atlas Quarries has been a supplier of quarry aggregates for almost 75 years. The company produces around 300,000 tonnes of material annually.
The RA40’s ‘robust’ construction and ‘superior’ capabilities are said to allow it to navigate the terrain of the Brynderwyn site. When working conditions are punctuated by steeper inclines and tricky ground structure, tractive effort can be increased by approximately 50%.
Rokbak added that the automated limited slip cross-axle and manually applied inter-axle differential locks distribute torque between axles and/or across the axles to limit wheel spin and maintain momentum.
“We are pleased to have partnered with Atlas Quarries in optimising its operations at the Brynderwyn site alongside our global parts dealer of the year, Porter Group,” added Lee Irving, Rokbak regional manager. “The success achieved with them in New Zealand and an increased Rokbak profile in the country demonstrates our commitment to delivering innovative, high-performance solutions tailored to the unique needs of our customers wherever they operate in the world.”
