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.
Driveline specialist Dana is launching the Spicer Rui Ma brand of transmissions and axles that are manufactured in China for the local market. This range complements Dana’s Spicer brand of sophisticated drivetrains and is being marketed in China as line-up with the features, performance, dependability, and the pricing structure preferred by many Chinese OEM manufacturers supplying local markets. The range has been developed at Dana’s manufacturing facility in Wuxi, Jiangsu Provence, China. The Spicer Rui Ma
Volvo’s two compact hydrostatic wheeled loaders, the nine and 10 tonne L45 and L50, have been upgraded to G-series specification. It means the compact loaders get a transversely-mounted, four-cylinder D4H engine that gives 74-86kW, and drives a twin-range hydrostatic transmission with 100% locking differentials on both axles.

Doosan Infracore Construction Equipment will take the covers off five new wheeled loaders at INTERMAT. The DL300-3, DL350-3, DL420-3, DL450-3 and DL550-3 large wheel loaders – with bucket capacities from 3.0 to 5.5cubic metres - get Scania SCR diesel engines that meet stage IIIB emissions regulations.
