System power
The energy recovery cylinder is a storage system which is inde-
pendent of the diesel engine. The system performance of material
handling machines fitted with the ERC system is composed of the
installed engine power and the energy recovery cylinder. When the
equipment is raised, energy from the ERC system is supplied in addi-
tion to the power from the diesel engine.

Lowering the equipment stores energy in the ERC system. This stored energy is then made available to the machine
to provide additional engine power. When the equipment is raised the stored energy is released and is reflected in
powerful, homogeneous operating cycles. The result is a clear saving on fuel – and, at the same time, even greater
performance.
