Abstract
An apparatus for lifting or moving a partition or panel may in one embodiment include a frame that is mountable to an interior surface of a cargo area and a locking mechanism comprised of smooth and knurled guide and locking pins through which a strap is fed. In preferred embodiments at least one knurled locking pin can slide between a locking position which inhibits strap movement and a non-locking position in which the strap is substantially free to slide through the lift mechanism. In certain embodiments a knurled locking pin may be operable to slide into a locking position when a load is placed on a lifting end of the strap, such as when the strap is connected to a panel which is being lifted or moved. The knurled locking pin may also be operable to slide to a non-locking position when a user pulls on the opposite end of the strap.
