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.
A new range of safety-focused automatic quick couplers will be launched by Geith at INTERMAT, specifically for mini excavators. The new QC35/40 hydraulic coupler is designed for use on mini-excavators from two- to four tonnes, giving the operator a fully automatic, safe change-over system without having to leave the cab. A patented double pin locking system ensures that the coupler retains the attachment in a safe position even if there is a loss of power, said the firm.
Dana used bauma 2013 to show a hydraulic hybrid concept for use with wheeled loaders, offering the potential to reduce fuel consumption by 20-40%. Called PowerBoost, the system uses high-pressure hydraulic accumulators to store up fluid power that can be released to assist the engine in driving hydraulic pumps and motors. “PowerBoost offers hydraulic power assistance to almost any machine function, to prevent peak loads on the engine during short duty cycles such as loading,” said Donald Remboski, Dana vice

Putzmeister’s new BSC 1409 D self-propelled concrete pump is designed for concreting drilled piles on unfinished surfaces and can deliver up to 85m3/hr at a pressure of up to 71bar. Powered by a 6-cylinder Deutz engine producing 129kW, the BSC 1409 D can travel at a maximum speed of 3.6km and does not need supports to be set up each time it moves.
