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.
Part of Wacker Neuson’s new DT series of crawler-mounted dumpers, the DT08 Proline is said by the firm’s product manager Steffen Wiesener to have a more efficient hydraulic system than the standard DT08 model, improved operating and control comfort and a wider range of attachments.

Komatsu has unveiled its 23,590kg operating weight WA470-7 wheel loader, which offers improved efficiency, lower fuel consumption, improved operator comfort and enhanced serviceability. It is powered by a 203kW Stage IIIB/ EPA Tier 4I Komatsu SAA6D125E-6 engine, which is said to lower fuel consumption by 10% to 15% compared with the WA470-6. The engine is fitted with EGR, a hydraulically-actuated variable geometry turbocharger, and an automatically regenerating DPF. As with all Komatsu Stage IIIB machines,
