Abstract:
An apparatus including a base, a guide arm pivotable relative to the base, the guide arm movable between a raised position and a lowered position. A tension linkage has a distal end extending away from the base, the tension linkage supported by the guide arm when the arm is in the raised position. A tension linkage guide is disposed on the guide arm, the tension linkage guide movable along the tension linkage as the guide arm moves between raised and lowered positions. A hook is connected to the distal end of the tension linkage. When the hook is engaged with an object, the tension linkage forms a first tension angle and a second tension angle when the guide arm is in the raised position and the lowered position respectively, the second tension angle being less than the first tension angle.
