ABSTRACT:
Apparatus for lifting and/or handling objects, preferably cylindrical objects such as pipe or the like. A first object engaging element has a first pair of arms pivotally secured to opposite sides of same. A second pair of arms are pivotally associated with said first pair of arms. A second object engaging element is pivotally secured between said second pair of arms intermediate the length of same for disposition on a side of said object opposite the first engagement element. A third object engagement is pivotally secured between said second pair of arms for disposition on a side of said object opposite said second object engagement element. An elongated lifting element is secured to the first object engaging element, and when lifting force is applied thereto, the first, second, and third engagement elements are brought into gripping engagement with the object. An elongated releasing element may also be associated with the object engagement elements for avoiding gripping engagement when desired.
