2304 ZF will focus on efficiency and reducing fuel consumption at this year’s show. The transmission and driveline component manufacturer will present its Ergopower efficiency package that combines the cPower continuously variable transmission with the ZF Hybrid module that should be commercially available in the future. cPower is a hydromechanical variable transmission that combines hydrostatic drive pumps with a mechanical powershift gearbox. Available for use in a range of machines, including wheeled loaders, telehandlers, graders and wheeled excavators, ZF claims that HVT can save up to 25% in fuel costs. The firm’s hybrid system will be able to be used with all forms of ZF transmission and could be incorporated in the transmission or separately in the machine for additional fuel consumption benefits.
Deutz used bauma to show two hybrid projects it is currently working on, including a hybrid drive for excavators and an innovative start/stop system for compact wheeled loaders. The hybrid drive is based on using a 160kW Deutz TCD 6.1 L6 engine with an integrated motor-generator. The engine is linked to an on-board electrical power network that uses super capacitors, a power inverter and an electric slew motor, allowing components to harvest, store and use electrical energy, specifically for slewing functio
Liebherr has developed a hybrid drive system for its HS8300HD heavy duty cycle crawler crane. The 350 tonne machine generates electrical power from its hydraulic free-fall winches, which offer up to 50 tonnes of line pull. Under this Pactronic system surplus energy is stored in a hydraulic accumulator and regenerated to assist the engine, reducing fuel consumption. This reuse of energy also cuts emissions from the machine.

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
