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.
ZF used bauma 2013 to show the next stage of development for its cPower continuously variable transmission (CVT). By combining the transmission with a hybrid module, ZF said greater operating efficiencies were available from the integration of start/stop technology and energy recovery from regenerative braking. Potentially, the hybrid drive system has the ability to boost fuel efficiency by up to 25% in addition to the 20% higher operating efficiency already offered by the cPower transmission, said ZF.
Chemical company Evonik has formulated an additive pack that creates multi-grade hydraulic oil for excavators. It is said to deliver a significant improvement in fuel efficiency compared to traditional mono-grade hydraulic oils.
It’s called Dynavis and the key, said Evonik, is a clever viscosity improver that prevents aeration, which can cause cavitation and a loss of performance in hydraulic pumps. Dynavis’ technology is a closely guarded secret - it is not available as a pour-in additive, but is sold in

A new development from JCB is an access platform attachment for use with the firm’s 535-140 and 535-128 model telehandlers. This has been developed to meet growing market demand for access platform attachments that can be used on telehandlers in a range of construction duties.
