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.

A cantilever cover, comprising: a first column and a second column, each of the columns having a lower end adapted for attachment to a support surface and an upper end; a linear crossmember extending between the upper end of each of the columns parallel to the support surface; a first sleeve and a second sleeve slidably disposed on the first and second columns, respectively; a winch centrally mounted on the crossmember; a first winch cable extending between the winch and the first sleeve and a second winch cable extending between the winch and the second sleeve; a winch activation switch remotely located from the winch and controlling actuation of the winch; a canopy frame attached to the first and second sleeves extending lateral to a plane defined by the columns and the crossmember; and a canopy cover attached to the canopy frame. 2. The cantilever cover according to claim 1, wherein each said canopy frame support sleeve comprises a closed tubular structure completely surrounding and enclosing a portion of a corresponding one of said columns. 3. The cantilever cover according to claim 1, further comprising a canopy support arm attached to each of said sleeves, each of the canopy support arm being an elongate spar extending beneath and completely across said canopy frame to each of said canopy frame support sleeves. 4. The cantilever cover according to claim 1, wherein said canopy frame has a raised central area formed by a plurality of laterally disposed ribs, each of the ribs having an elevated central portion. 5. The cantilever cover according to claim 1, wherein said canopy cover further includes a depending skirt having a hem with a flaccid weight disposed therein. 6. The cantilever cover according to claim 1, wherein said winch is electrically powered. 7. The cantilever cover according to claim 1, further including at least one limit switch adapted to shut off operation of said winch at a predetermined point of travel of said canopy assembly relative to said hoist assembly. 8. A cantilever cover, comprising: a hoist assembly, including; a plurality of substantially vertical columns, each of the columns having a front face, a back face, and an upper end; a closed, canopy frame support sleeve slidably disposed upon and enclosing a portion of a corresponding one of the columns; first and second, diagonally opposed sleeve rollers extending from each of the sleeves, the first roller bearing upon the front face and the second roller bearing upon the back face of a corresponding one of the columns; a substantially horizontal upper crossmember joining the upper ends of the columns together; a winch mounted upon the hoist assembly; a canopy assembly lift cable extending from the winch to each of the canopy frame support sleeves; a remotely disposed winch actuation control switch extending from the winch; a canopy assembly, having; a canopy frame; a canopy cover removably disposed over the canopy frame; and a canopy support arm extending from the canopy frame to each of the canopy frame support sleeves, permanently and immovably affixing the canopy frame to the canopy frame support sleeves, the canopy support arms extending therefrom in a substantially parallel array. 9. The cantilever cover according to claim 8, wherein: said winch comprises a single winch mounted centrally upon the upper crossmember of said hoist assembly; and each said canopy assembly lift cable is substantially equal in length to one another. 10. The cantilever cover according to claim 8, wherein each said canopy support arm comprises an elongate spar extending beneath and completely across said canopy frame to each said canopy frame support sleeve. 11. The cantilever cover according to claim 8, wherein said canopy frame has a raised central area formed by a plurality of laterally disposed ribs, each of the ribs having an elevated central portion. 12. The cantilever cover according to claim 8, wherein said canopy cover further includes a depending skirt having a hem with a flaccid weight disposed therein. 13. The cantilever cover according to claim 8, wherein said winch is electrically powered. 14. The cantilever cover according to claim 8, further including at least one limit switch adapted to shut off operation of said winch at a predetermined point of travel of said canopy assembly relative to said hoist assembly. 15. A cantilever cover, comprising: a hoist assembly, including; a pair of substantially vertical columns, each of the columns having a front face, a back face, and an upper end; a canopy frame support sleeve slidably disposed upon each of the columns; first and second diagonally opposed sleeve rollers extending from each of the sleeves, the first sleeve roller bearing upon the front face and the second sleeve roller bearing upon the back face of a corresponding one of the columns; a substantially horizontal upper crossmember joining the upper ends of the columns together, the crossmember being permanently and immovably affixed to the columns; a winch mounted upon the hoist assembly; a canopy assembly lift cable extending from the winch to each of the canopy frame support sleeves, each of the cables being substantially equal in length to one another; a remotely disposed winch actuation control switch extending from the winch; a canopy assembly having; a canopy frame; a canopy cover removably disposed over the canopy frame; and an elongate canopy support arm extending beneath and completely across the canopy frame to each of the canopy frame support sleeves. 16. The cantilever cover according to claim 15, wherein said winch comprises a single winch mounted centrally upon the upper crossmember of said hoist assembly, each of said canopy assembly lift cables being substantially equal in length to one another. 17.
