ABSTRACT:
An improved roll-up truck cover assembly for dump trucks and the like having upstanding side and end walls defining an upwardly open body for receiving particulate material. The cover assembly comprises a flexible top cover substantially coextensive with the body cross section viewed from above and one end of the cover extends across and is attached to one end portion of the body. A take-up roll for the cover has a spring bias for rotation in a take-up direction and is mounted on a pair of arms at upper end portions of the latter. Lower end portions of the arms are pivotally attached externally at sides of the truck body to swing the take-up roll through a long shallow arc in a lengthwise traverse of the truck body. With the take-up roll at an opposite end portion of the body and the cover in closed position over the upwardly exposed opening in the body, a braking apparatus secures the take-up roll against inadvertent rotation whereby to maintain the cover in a taut condition over the opening.
