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.
AFW350 and AFT350 are the latest medium-sized asphalt pavers from Ammann and are said to offer good manoeuvrability in confined areas. The hydrostatically driven machines offer a paving width from 1.8-3.5metres and the output potential of up to 230tonnes/hour. A wide range of optional equipment is available to improve paver performance. These include a vibratory screed or a tamping/vibratory screed that can be heated with either gas or electricity, and automatic lighting and temperature control functions.
JCB has launched its first five-stage-boom Loadall telescopic handler. The 540-200 has a 20m working height and a maximum lift capacity of 4tonnes. Using the same driveline as the 540-170, the machine is powered by JCB’s 75kW Dieselmax engine. The Loadall has a four-speed powershift transmission and uses a single servo joystick to control all boom functions.

The combination of innovative safety features in a new quick hitch device for hydraulic excavators has earned a silver award for Klac in the INTERMAT Innovation Awards 2012. The new Klac + quick hitch device comes in three models for machines of 8/9tonnes to 24/25tonnes. It has been designed to open up new markets for the company, which has specialised in quick coupling systems for 11 years but had previously focused on smaller machines.
