One way haul

24 April 2008

Bathgate Silica Sand, Arclid, Cheshire, UK is Using a 31 Tonne Volvo L220E For primary extraction and load and carry duties at its South Arclid site.

The L220E is equipped with a specially modified 5,4 m scalloped bucket, standard 29,5 – 25 XHA tyres and a 12 litre 261 kW Volvo engine. The optional ride control, or boom suspension system, means the machine is capable of extracting from the face and carrying 11 tonnes per bucket load on one way hauls of up to 400 m to field hoppers strategically placed in the quarry. Production is helped by a rapid torque rise from the 12 litre engine, peaking at just 1200 rpm, combined with the Volvo HTE305 countershaft transmission, which offers smooth gear shifting thanks to its PWM (Pulse Width Modulating) valve system. All the operator has to do is select forward, reverse or kickdown and the APS II (Automatic Power Shift) takes care of the rest. To complete the powertrain, Volvo's own AWB (All Wet Brake) axles are used. The front axle features a 100% differential lock and the rear axle cradle is maintenance free.
