Post lift for vehicles

Abstract

The post lift (1) for vehicles comprises: at least one supporting post (2); at least one sustaining element (4) associated with the post (2), sliding along a substantially vertical direction and positionable in contact with a portion of a vehicle to be lifted; at least a fluid operating actuator device (7) associated with the sustaining element (4); at least a pumping device (8) associated with the actuator device (7) through a first closed circuit (9) and suitable for pumping a first fluid towards the actuator device (7) to move the sustaining element (4) from a lowered position to a raised position; an exhaust valve (10) associated with the first circuit (9) and which can be operated to allow the first fluid to flow from the actuator device (7) to move the sustaining element (4) from the raised position to the lowered position; a second closed circuit (21) associated with the exhaust valve (10) and a manual device (22) for varying the pressure of a second fluid inside the second circuit (21) between a minimum pressure value, in which the exhaust valve (10) is closed, and a maximum pressure value, in which the exhaust valve (10) is open.
