Abstract :
Electro-hydraulic systems of heavy machines operating at different potential energy levels, using e.g. a lifting boom are evaluated. Practical results are found by using a light electro hydraulic forklift in measurements. A heavier diesel hydraulic forwarder is studied theoretically using the experimental results of the forklift as base data. An analysis of the efficiency of the energy recovery from a lifting boom of a forwarder is done.
