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.
JCB will launch 427 and 437 wheeled loaders at Bauma, powered by Stage IIIB/Tier 4 Interim Cummins engines. First seen in prototype form at last year’s Intermat show, the two loaders are powered by the Cummins QSB6.7 engine, which offers a 9.4% increase in torque over the previous model. This drives through a lock-up converter and customers can choose a standard four-speed or optional five-speed transmission, which delivers a 16% drop in fuel consumption. In-cab noise levels have been reduced to just 68dB(A
Ausa is extending its Taurulift compact telescopic range and will launch the new T 235 H at INTERMAT. The company will also show its recently launched T 144 H for the first time.

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.
