The present invention relates to an apparatus for covering and uncovering a top side of a container carried by a vehicle. The apparatus includes a base mounted to the vehicle and a frame pivotally mounted to the base. The frame is rotatable relative to the base between a first position and a second position. A reel is mounted to the base and a flexible sheet is wound on the reel, with one end of the flexible sheet attached to the frame. A first driving device is coupled to the reel for winding and unwinding the flexible sheet. A second driving device is coupled to the frame for rotating the frame from the first position to the second position. When the flexible sheet is unwound from the reel, the frame rotates towards the second position to extend the flexible sheet over the container to cover the container. |
