Abstract:
Method and apparatus for gripping and lifting heavy and cumbersome objects is disclosed. A slotted safety latch lever assembly permits the pivoting action of an upper tube relative to a main tube, facilitating the gripping and releasing action of arm assemblies at either end of the main tube. The length of the main tube is adjustable, permitting the main tube to shorten or lengthen as needed for gripping the object. The upper tube has a lifting device connector selectively positioned longitudinally relative to the upper tube for achieving correct balance point for lifting.
