(57) A lifting device (1), particularly for lifting wheels of vehicles and the like, for
wheel balancing and tire removing machines, comprising a scissor-like frame (2), which
is interposed between at least two flat and mutually parallel elements (3, 4) for
their mutual translational motion as a consequence of the action of motor means (5)
functionally associated with the scissor-like frame (2), the lifting device further
comprising cam-type profiled means (7), which can be engaged functionally with the
motor means (5) for dynamic and static balancing between the thrust force generated
by the motor means (5) and the contrast force of the scissor-like frame (2) in addition
to the weight of the object (6) to be lifted, which is arranged on one of the two
flat and parallel elements (3, 4), in all the operating positions of the lifting device
(1).
