Abstract

An arrangement for a hydraulically operated lifting arrangement, for example a so-called tail lift, comprising at least one cylinder/piston unit (8) for actuating a lifting platform. This is connected via a hand valve (7) to the pressure side of a pump (2) by means of a hydraulic line (10). The pump (2) communicates on its suction side with a hydraulic tank (3), and on its pressure side with a pressure accumulator (6). A characteristic feature of the invention is that the arrangement comprises two hydraulic machines (4, 5) acting as a pump/motor and operatively connected via their shafts (14) and in a previously disclosed manner. These are reversible, and one of the hydraulic machines (5) is connected to the line (10) between the pressure side (2) of the pump and the valve (7). The other hydraulic machine (4), which is also capable of being regulated, is connected in parallel with the pump (2).
