The model in question is a Volvo R70D rigid hauler, and although this is a new machine, it has a rich history that dates back more than 70 years to when the team of technical experts and engineers introduced the world’s first off-road dump truck from the Volvo CE facility in Motherwell, Scotland. Now backed by the Volvo CE design and manufacturing core values the R70D, along with other models in the range, are built at the same facility that has produced rigid haulers for decades. “We conducted a competitive evaluation of the rigid hauler market and since we have over twenty Volvo branded machines operating here at Linhay and our other facilities, concluded the best choice of hauler would be the new Volvo R70D,” comments Richard Webb, Operations Manager of Quarry and Concrete Products for E&JW Glendinning. “The new Volvo has a long-standing pedigree with its Terex heritage, and it carries on the work of our existing eighteen-year- old TR70 which has worked tirelessly here at Linhay. The R70D is well matched to our resident prime loading machine which is a Volvo L350F, dispatching the truck in just four passes. It will be working one single shift, five days a week, delivering
approximately 250,000 tonnes of material from the face to the processing plant per annum.”
Powered by an MTU Detroit Diesel V12 engine developing 695 nett hp, the Volvo R70D achieves high performance and impressive maximum torque of 3323Nm at the relatively low engine speed of just 1350 r/min. On top of that, long service intervals and efficient use of fuel provide exceptionally low operating costs.
Electronic integration between the engine and transmission allows the hauler to achieve smooth gearshift quality for consistent momentum and acceleration on all hauling applications. Performance and fuel efficiency are enhanced by the integrated shift pattern system, which includes two transmission shift schedules – Power and Economy – for tailored performance on all hauling conditions. The operator can pre- select the transmission operating mode to adapt to varying haul loads. Meanwhile, the hydraulic systems provide necessary flow for cooling and actuation systems that provide the required productive performance for quick cycle times and efficiencies.
