ABSTRACT:
A tarp cover system including a pawl (44) and ratchet (26) mechanism for locking a tarp cover (6) in a rolled-up truck-body-uncovered condition, and a brake operating lever that is initially pivoted in one direction with one hand by the operator to release the pawl from the ratchet to unlock the rolled up cover, and is subsequently pivoted in the same direction by the same hand to brake the unwinding of the cover as it is spring-biased toward the truck-body-covered condition. To re-cover the truck body, a crank shaft (24) is rotated to rotate the roll in the cover-winding direction against the biasing force of the cover spring, the ratchet mechanism preventing uncontrolled unwinding of the cover.
