Abstract (en)
[origin: WO9511190A1] The electrohydraulic lifting device for motor vehicles includes a pair of support platforms (1), respectively a first support platform and a second support platform, which are horizontal and parallel to each other, and mounted on respective tie rods (2) respectively actuated by a main cylinder (P1) and by a secondary cylinder (P2) fed by the same main cylinder (P1), under the control of a hydraulic control unit (16). The hydraulic control unit (16) is equipped with a synchronisation device (17) including a synchronization valve (18) aimed at connecting a hydraulic media conduit (20), delivering hydraulic fluid to the said main cylinder (P1), with a recycling conduit (22) leading a suitable volume of hydraulic fluid from the same main cylinder (P1) to the secondary cylinder (P2), so that to compensate the inadequacy of the delivery of fluid to the secondary cylinder (P2), or alternatively aimed at deviating an exceeding part of the recycled fluid to a discharge, respectively at the starting and when the support platforms (1) are getting into alignment at the floor level.
