Problems solved by technology

[0024] In the first case, this inevitably requires the use of complex control electronics and thus increases the overall cost of manufacturing the lift
[0025] On the other hand, in the second case, the lift user is forced to equip the workstation with an external air supply circuit, which, in addition to increasing the overall cost for the user himself, is often not easily achievable

Embodiment Construction

[0036] With specific reference to these drawings, generally indicated by the numeral 1 is a post lift, which is of the type commonly used in motor vehicle garages / workshops for lifting vehicles so that the vehicles themselves can be accessed by the operator The lower part is used for normal maintenance or repair work.

[0037] The lift 1 comprises: a pair of support columns 2, each of which has a base 3 capable of being secured to the ground; two supports 4, connected to the respective columns 2, slideable and positionable in a substantially vertical direction into contact with respective corresponding parts of the vehicle to be lifted;

[0038] In particular, not only with reference to the embodiment of the lift 1 shown in the drawings, on each column 2 is fitted a vertically sliding trolley 5 suitable for supporting a pair of supports 4 .

[0039] Each support 4 consists of a horizontal telescopic arm of adjustable length, one end of which is hinged to a trolley 5 about a v...

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.

Description

technical field [0001] The invention relates to a post lift for vehicles. Background technique [0002] It is known in motor vehicle garages / workshops to lift a vehicle using so-called "lifting" equipment, in order for the operator to gain access to the lower part of the vehicle itself for normal maintenance and repair work. [0003] A specific and widely used type of such equipment is the "post lift". [0004] A column lift generally includes: a pair of vertically parallel and spaced support columns; a vertically sliding trolley on each column adapted to support one or more horizontal telescopic arms , the trolley has pads at its free ends, said pads being positionable in contact with respective corresponding lower parts of the vehicle to be lifted; operating means for operating the lifting and lowering movements of the trolley. [0005] It is also known that conventional international safety regulations require on pole lifts a device for holding the arm during the stands...
