ABSTRACT:
This invention relates to a cover rolling mechanism for barge covers an inverted U-shaped bar is welded to the push knees of the tugboat and the sheave is supported on top of such bar. A winch is supported nearby on the floor of the tugboat. A cable is entrained over the sheave and pulled by the winch after the end of the cable has been hooked on a double top cover of the barge, which cover, together with other covers protects the lime, or other load in the barge, from rain or other elements of weather. The cable may be re-attached to other covers to affect nesting on top and bottom covers which roll along tracks on the barge. An even central pull is thus affected on the covers.
