2254 Dana Rexroth’s HVT R3 is a hydro-mechanical variable transmission for wheeled loaders with engine outputs of up to 265kW and is the first power split transmission from the joint venture between Dana and 2253 Bosch Rexroth
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.
Komatsu used INTERMAT to take the wraps off two new Dash 7 wheeled loaders, badged WA380-7 and WA500-7. With engine emissions being the main driver, the smaller 18-tonne WA380-7 packs 142kW from its EU Stage IIIb engine to deliver improved efficiency and lower fuel consumption. The machine also gets torque converter lock-up with the function operating in 2nd, 3rd and 4th gears, and gives the loader a 40 km/h forward speed.
Haulotte has introduced the Compact C10DX and C12DX rough terrain scissors lifts. Powered by a Stage IIIB Kubota engine, the machines produce lower noise levels and use 5% less fuel than previous models. The C10DX offers a maximum working height of 10.15m, while the larger C12DX has a 12.15m working height.
