Using a combination of hydrostatic and mechanical drives, the technologically advanced three-range transmission can offer up a fuel saving of up to 20% by delivering a stepless speed range from 0-40km/hr without clutches and without interrupting the drive.
Cleverly, the HVT R3 will allow the operator to preset a maximum travel speed, or preselect a fixed engine rpm and use the transmission’s characteristics to keep the engine working at its most fuel-efficient point.
Greater fuel efficiency, improved digging performance and revised styling are among the changes to be found on Volvo’s latest D-series wheeled excavators. The four-model EW range spans 14-21tonnes and benefits from a new engine, cab, hydraulics, substructure, boom, arm and controls. There is more power with D-series, from stage IIIB engines that use V-ACT technology. The four cylinder (EW140D) and six cylinder engines produce high torque at low engine speeds, said Volvo, giving rise to low fuel consumption.
The D65-17 dozer gets an 8.9litre stage IIIB certified Komatsu engine, and with 152kW at 1,950rpm, brings a net power increase while reducing fuel consumption by over 5% when compared to the model it replaces.

The ‘world’s smallest crusher bucket’, the MB-L160, made its debut at INTERMAT on the MB stand. Weighing just 1,350kg, the 0.3m3 capacity bucket has a throughput capacity of up to 22.5tonnes/hr and fits to machines between seven and 12tonnes, including backhoe loaders. Product size adjustment ranges from 15mm to 50mm.
