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.
