A cover system (10) for an open-topped container, such as a transfer trailer (T), includes a cover (11) carried by a support frame (13) pivotably mounted to the container. The support frame includes a triangular construct (20) at the opposite ends of the container to improve the rigidity of the cover system. A continuous drive shaft (28) extends along the length of the container and is connected to the support frame. A drive assembly (15) rotat es the continuous drive shaft to pivot the cover between retracted and deployed positions. The drive assembly is reversible to accommodate covers mounted on either side of the container.
