Abstract (en)
[origin: EP1239167A1] The lifting gear (10) has a motor (M) driving a pump (P) which draws oil from the reservoir (11). A bypass system (L1) with valves (18,19) may return some of the oil to the tank suction valve (12). The system includes a non-return valve (14) and a shutoff valve (15). There may be two actuator cylinders (13) with position sensors.
