ABSTRACT:
The lift platform (16) of a lifting apparatus (10) can be raised and lowered by means of an hydraulically operated lifting device (12). The back rest (18) can be swivelled backwards and forwards by a swivelling means (19), which is likewise hydraulically operated. Both working devices (12, 19) are connected to a multi-valve housing (20), which is located beneath the lift platform (16) and which has no manual control means at all. The valves are triggered hydraulically by remote control. For this purpose, a manual control unit (30) with a number of built-in servo valves is connected to the multi-valve housing (20) via a flexible cable (28), which contains a number of thin control hoses and an hydraulic water supply hose.
