The cantilever cover is suspended from one side over an article to be protected from the elements. The cover has a canopy frame and flexible, weatherproof canopy or cover secured thereover. A pair of canopy frame support arms extends from corresponding closed sleeves, which ride up and down upon the vertical support columns of a hoist assembly. Each sleeve includes a pair of diagonally opposed rollers, which bear against opposite sides of its respective column. A single winch (electric, hydraulic, pneumatic, etc.) is mounted centrally upon an upper crossmember extending between the two columns, with opposed equal length cables extending to the two canopy frame support sleeves. A remote control extends down the hoist frame from the winch, for operation of the device. One or more limit switches may be installed to limit the maximum or minimum travel of the canopy frame and cover.
