An apparatus used to lift and lower an object, such as a canopy covering placed on a truck's opened bed. A T-shaped load engaging platform member has a vertically adjustable sleeve mounted on the platform's vertical member whose position on the member can be adjusted and fixed along its height. A combined winch and cable controlled pivoted arm assembly having two joined pivotally arms, one of which arms is pivotally mounted to a vertical stationary support structure at its other end, is used to vertically support the engaging platform member above the ground at the end opposite the stationary support. A single operator can both raise and lower a load supported on the platform by rotating a handle on the winch assembly and directing the movement of the supported load. |
