摘要： The hoisting device comprises two ramps rigidly connected, intended to support at least one of the wheel pairs of the vehicle to be hoisted and including a single acting hydraulic cylinder operative to rotate the ramps upwardly from the position with the free end thereof resting on the floor. The ramps are pivoted at one end thereof at a selected level to two floor engaging side plates and a hydraulic system is provided for pivoting the ramps which cooperates with a safety mechanism against the unintentional lowering of the ramps.
