E & JW Glendinning Ltd has taken delivery of the first Volvo rigid hauler to be sold in Great Britain which has been put in charge of hauling blasted material to the primary crusher at the company’s Linhay Hill Quarry, Ashburton, Devon.
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, considered 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 a 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 an 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.
Offering good material retention, the abrasion resistant 41.5m³ high-capacity body is made of HARDOX 400 steel specification with exhaust heating to ensure clean dumping and minimal material carry-back and has a maximum payload is 65 metric tonnes.
Straightforward in design, the R70D is equipped with a frame assembly that incorporates a reserve of structural strength well beyond the requirements of every demanding job site condition. With a balanced weight distribution, thanks to a centrally mounted transmission, and a low centre of gravity, all load impacts are equally distributed across the tyres and a maximum speed of 57 kph is achieved through the six-speed Allison transmission. Able to withstand extreme structural stresses, the rigid haulers’ high-strength chassis absorbs shocks and vibrations from road conditions and load processes, for greater structural longevity and lower cost of operation through reduced maintenance.
Established in 1958, E & JW Glendinning produces quarry products, concrete products and asphalt from their facility at Linhay Hill Quarry Ashburton with satellite outlets strategically located in Plymouth and Exeter. They also produce high PSV gritstone chippings and asphalt from their Pigsdon Quarry operation located near Bude in North Cornwall. In addition to this, the company also operates a road maintenance division, contracting to private concerns and local authorities in Devon.
