Abstract (en)
[origin: EP0461638A1] In order to permit synchronisation of two supporting members (6 and 7) of a lifting platform, in particular for motor vehicles, which supporting members (6 and 7) can each be lifted individually by means of a hydraulic lifting cylinder (2 or 3), each supporting member is connected directly or indirectly in a fixed manner to a synchronisation rod (9 or 10). The two synchronisation rods are connected in an articulated manner (12, 13) to a control rod (11). A control cylinder (19) is connected between the control rod (11) and at least one synchronisation rod (9). If there is only one control cylinder, a shuttle valve (67), among other things, is required in order to obtain the synchronisation of the supporting members (6 and 7) via the hydraulic control system. Instead, a second control cylinder (20) can be connected between the control rod (11) and the other synchronisation rod (10). <IMAGE>
