Plate Lifting Clamp
US Patent:
4884836, Dec 5, 1989
Filed:
Aug 9, 1988
Appl. No.:
7/230815
Inventors:
David Maye - West Hempstead NY

Moon Choung - Melville NY
Assignee:
Cooper Industries, Inc. - Houston TX
International Classification:

US Classification:

Abstract:
The plate lifting clamp of the present invention includes linkage disposed on the clamp with one end of the linkage connected to the lifting shackle and the other end of the linkage connected to a cam rotatably mounted on the clamp. A spring on the linkage causes the cam to rotate against the work piece gripping the work piece between the cam and a swivel pad mounted on the clamp. A further force is applied to the rotation of the cam as the work piece is lifted on the lifting shackle by the hoist. An operating handle is rotatably disposed on the clamp whereby when rotated to the open position, will cause the cam to rotate away from the work piece and open the clamp. A spring biased locking mechanism is provided on the clamp to lock the operating handle into the open position.
