A linkage with reduced starting load for moving the ramps (1) of compact auto lifts comprising a base carriage (4) which can slide at floor level on a corresponding footing (5) and has a preset horizontal stroke, an end of a fluid-actuated actuator (6) and a contiguous end of a linkage element (7) being respectively coarticulated to said carriage (4), the length of said actuator (6) being axially variable, said linkage element (7) having eccentric means (8) for a partial rotation of said linkage element (7) on a vertical plane, the opposite end of said linkage element (7) being in turn slidingly articulated in a hinge-like manner, by way of corresponding articulation means (9), to the body of a lever (10) for lifting the corresponding ramp (2) by contact, the opposite end of said actuator (6) being articulated to a rod-like member (2) which composes a pantograph structure for lifting said ramps (1). <IMAGE> |
