Abstract
Gravel boxes, open top containers with rolling roofs, and related methods. The rolling roof is used to cover open top containers for dry or liquid loads. The rolling roof may be manually operated with a ratcheting handle or motor in combination with two rolling mechanisms placed on each side of the roof. The rolling roof mechanism may be implemented by sliding the roof either to the left or to the right side of the container, and turning it from a horizontal position to a vertical position along the side wall. Such allows loading from either side of the container by using the full area of the opening.
