A truck cover assembly is provided having an improved telescopic arm assembly for drawing a flexible cover across an upwardly open truck body or container. The front mounted assembly is secured to a portion of the truck frame between the cab and the body, and comprises a pair of pivoting telescopic arms, a drive motor, a flexible truck cover, a tie-rod, and a cover housing. As the drive motor moves the arms fore or aft, arm mounted actuators cause the segmented arms to extend or retract so that the tie-rod connecting the upper arm ends and securing one end of the cover, travels horizontally over the upper edge of the body in close proximity to it. Extension or retraction of the telescopic arms occurs simultaneously and proportionately with the rearward or forward pivoting of the arms. The cover housing, optionally mounted on a retractable gantry, protects the cover and incorporates a spring tension device to assist in smoothly rolling and unrolling the flexible cover.
