Abstract
A retractable tarpaulin that can cover the cargo of truck, either partially or entirely. This system comprises a pair of posts that slide in notches at the periphery of a trailer flat bed, at the desired position according to the size of the cargo to cover. The width is also adjustable and includes an overhang of up to 12″ on either side. The length may be reduced or extended at both front end and aft end if needed. The height of these posts can be adjusted to adapt to the cargo. A series of cables covers the distance from one post to the other to support the tarpaulin and a drum arrangement stretches the cables to provide tightness to support the tarpaulin. As the tarp is retracted a number of rings attached to the tarp are successively engaged in a cantilever hanger to keep the tarp in a small storage when not in use.
