An apparatus for covering an open top of a transportation trailer container includes a frame on top of the container. The frame surrounds an aperture for flow of material into the container. The apparatus also includes an arm pivotable between a closed position and an open position. The arm holds a rotatable roller for dispensing and receiving a flexible cover. The flexible cover is wrapped around the roller when the arm is in the open position. The flexible cover is unrolled from the roller to cover the aperture due to motion of the arm from the open position to the closed position. The frame includes a side portion having an inwardly and upwardly tapered outer surface. The roller contacts the outer surface when the arm is in the closed position.
