Abstract

See full text

An apparatus for righting or picking up overturned vehicles is provided. In the illustrated embodiment, the apparatus is a truck-mounted turntable able to rotate in either direction supporting a first pair of parallel frame members which are moved through a range of angularly elevated positions by hydraulic jacks. The first parallel frame members support a second pair of parallel frame members which are also deflected relative to the first pair by hydraulic jacks. A third pair of parallel frame members telescope inside the second pair, and they are extended by hydraulic jacks. The third pair terminates at a transverse frame member which is pin-connected to a pair of legs when the apparatus is extended to obtain support. The extended apparatus includes, at multiple locations, cable winches having spools with a cable wound thereabout. The cables are able to be extended and retracted and connect to slings adapted to be passed beneath an overturned vehicle such as a tractor-trailer rig. The slings are lifted to raise the overturned vehicle, and, through the use of a winch at each end of each sling, the overturned equipment can then be elevated and turned erect.
