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.
Latest Volvo wheeled loaders to get the G-series revisions include the middle-weight 11-17 tonne L60, L70 and L90 versions. The stylish overhaul brings an electrically operated sloping bonnet, improving rearward visibility. All benefit from a revised cab layout, cleaner engines and improved hydraulic systems to deliver more productivity and greater efficiency. Power ratings are from 121-130kW, with all three sharing a stage IIIB six-cylinder Volvo D6H motor that gets cooled EGR and DPF emissions equipment.
Two new short radius excavators are being introduced by Case Construction Equipment at INTERMAT. The Japanese-built CX235C SR and a prototype CX145C SR use low emission Isuzu engines with cooled EGR and a DPF to meet stage IIIB emissions requirements, and Case reckoned the new engines provide a 17.5% fuel consumption improvement over previous models, while simultaneously delivering up to 7% cent faster cycle times.
