ABSTRACT:
The present invention entails a hydraulically actuated tarp retraction and extension system for a truck wherein the system provides for the automatic extension or retraction of a tarp about the load bed of the truck. A tarp reel assembly is provided and includes a a tarp which is biased by the reel assembly itself to assume a wound or retracted position. A pair of swing arms are connected to a leading edge of the tarp and are in turn connected to a hydraulic control system which is operative to extend the tarp to a covered position over the load bed and wherein the tarp reel assembly is operative to wind the tarp in response to the arms being moved towards the tarp reel assembly. In one mode of operation, the hydraulic control system automatically provides for the retraction of the tarp in response to the load bed of the vehicle being raised from a horizontal position to a generally vertical dumping position.
