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.
Case says its three new M Series dozers being introduced at bauma – the 1150M, 1650M and 2050M – offer a 10.5% fuel saving, and 19% increase in productivity, compared to the previous generation of machines, due to their claimed best-in-class engine reaction. With operating weights from 13-20tonnes and like other M Series models, the three new dozers are powered by fuel-efficient, Tier 4 Interim FPT engines, using a proven Selective Catalytic Reduction (SCR) technology.

The latest addition to Komatsu’s heavy duty crawler excavator range is the PC490, one of the new line-up of Dash 10 generation machines being introduced. The operator comfort and controls have been upgraded from the previous Dash 8, while six working modes allow the machine functions to be matched to the duty cycle for efficient working.

Monsieur Bernard Accoyer, the president of the French National Assembly, officially opened INTERMAT 2012 with a traditional ribbon cutting ceremony. Equipped with gold-plated scissors, M Accoyer paused for the media before slicing through the tricolour ribbon on his way to an extensive 90-minute tour of the show’s exhibition halls, to savour all that the construction industry has to offer.
