A winch including a winch motor and a winch reel rotatable relative to the winch motor about a reel axis is secured to the first end portion of the support member and a flexible tension link is windable on the reel. The apparatus is provided with provisions for releasably connecting the second end portion of the support member to an object such that the first end portion projects from the object, the releasable connecting provisions being dimensioned and positioned on the second end portion to resist forces imposed by the winch on the support member to prevent movement of the support member relative to the object.
