ABSTRACT:
A lifting plate for chains. A simple plate with three separate openings. A center opening has a rounded shape, is high on the plate and has a narrow slot extending down the plate centerline to form a balloon-like outline. The other two smaller openings have wide upper portions with narrow slots extending downward and are located in a balanced configuration on either side of the lower slot of the larger hole. The upper parts of the smaller holes are sized too small to permit the chain end hooks to freely pass through, but they are located closed enough to the edge of the plate to permit the hooks to be moved through the holes by twisting them through. The three holed configuration permits creating double chain slings with different lengths of chain in each leg and storing the excess chain between the holes.
