Abstract:
1. A roll-tarp assembly for covering and uncovering a container opening, said assembly comprising: a tarp, a rotary power shaft, a roll bar attached to said tarp for rolling said tarp from a first unlatched position over the container opening to a second captured position and then subsequently rotated to a latched position, a first connector configured for transferring rotary power to said roll bar, a second connector configured for receiving rotary power from said power shaft, and a resilient member having opposite first and second ends attached, respectively, to each of said first and second connectors configured for transferring rotary power from said first to said second connector and allowing limited, force-responsive rotation in said captured position of said first connector in a tarp tightening direction relative to said second connector during movement of said roll bar to its latched position, so as to help minimize excessive torque on said roll bar in said tarp tightening direction during movement from said captured to said latched position.
