ABSTRACT:
A cover system for covering an open topped compartment, such as a truck trailer, that may contain a quantity of particulate material extending in a heap above the sides of the compartment. A sheet of flexible material is rolled at one compartment end for pulling across and covering the compartment. A transverse tube is secured to the cover leading edge. A roller assembly is mounted by brackets to the tube so that as the cover is moved over the heap of material the roller will engage the heap and rotate so that the brackets raise the leading edge above the roller, which rides along the heap. The cover is then fastened in the covering position. When the cover is retracted to uncover the compartment, the roller trails behind the leading edge, permitting the cover to be rolled up easily.
