IMPROVED ROLL-UP TRUCK COVER ASSEMBLY ABSTRACT OF THE DISCLOSURE 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 co- extensive with the body cross section viewed from above and one end of the cover extends across and is attached to one end por- tion 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 posi- tion 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 open- ing. -1-
