ABSTRACT:
The apparatus is a snow and ice remover for the roofs of trucks and trailers. A bridge like structure of two vertical beams and an upper cross piece supports a vertically adjustable snow plow assembly which rolls on wheels riding on the vertical beams. A wedge shaped plow forms the lower edge of the snow plow assembly so that when a snow or ice covered truck or trailer moves under the properly positioned plow, the snow or ice is pushed off the top of the vehicle. The snow plow has a minimum height below which it can not be lowered, and the adjustment of the snow plow is powered by a winch on the cross beam which reels in or releases a chain from which the snow plow is hung.
