Abstract
The maneuvering device comprises two hydraulic motors (14, 15), each attached to the base of each screw (4, 5) integrated into each post (2, 3) of a pair of posts. The hydraulic motors (14, 15) are supplied in series by a single course of pressurized fluid and each shunted through a bypass comprising a hydraulic shunt which opens either automatically or is regulated to open completely, partially or progressively. This invention is of particular interest to auto body manufacturers for use on road trailers for carrying vehicles.
