Abstract
Abstract This disclosure concerns a vehicle-hoisting installation having a first carrying assembly carried by a four-column support structure which has a device for driving this first carrying assembly. A second carrying assembly independent from the first but supported by the first carrying assembly when it is not hooked to the columns by hooking means, allows the vehicle be supported by the second assembly at points other than the wheels thereof, to maintain the vehicle in a raised position when the first carrying assembly is lowered. The second carrying assembly includes at least two bars which are directed transversely with respect to the direction along which the vehicle is engaged on the installation, and which are disposed with in the longitudinal distance between the vehicle wheels.
