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.
Italian crusher manufacturer REV has updated its Zeffiro GCV80 crusher, with a Stage IIIB Caterpillar engine, improved electrics and additional safety guards on the conveyors. Designed primarily for the demolition and recycling industry, the machine uses a 130kW version of the Cat C6.6 motor, driving through a variable displacement load sensing hydraulic system.
Cat has revised its asphalt compactor range with Stage IIIb engines, revised drum options and a new cab layout. The changes also bring an all-new model – the CD44B – in the seven/eight tonne class, taking the model count to four. A revised cab now gives better sightlines to the drum edges and while the lateral side-shift for the operator’s seat has been retained, the previous 180-degree rotation is now extended to 360-degree rotation, giving the operator more freedom

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.
