Fork lift truck    

In order to demonstrate and test the technologies Innas and NOAX fitted a Lift truck with a CPR system. Two transformers were used in this drive system, one four-quadrant transformer for the hydrostatic wheel drive, and a 2-quadrant for the control of the lift cylinders. Throttle valves are used for the other cylinders. Although this results in some energy losses, the energy consumption of these loads is low compared to the lifting and drive functions.
The power source consists of a Chiron Free Piston Engine delivering 17 kW net hydraulic energy. Breaking energy and energy of lowering the load are recuperated. This combined with power management (peak shaving) made it possible to reduce the installed engine power with 30%.
