  • Patent number: 4941698
    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.

  • Patent number: 4909550
    Abstract: A lifting fixture for objects with a hollow core such as paper rolls. A relatively thick base plate with two parallel slots accepts a channel shaped fixture which protrudes up through the slots and forms a saddle for a web lifting strap. The channel also includes end tabs extending parallel to the base plate surface and bearing upon it to relieve the corner stress in the base plate slots. An upright cylinder attached to the assembly aids in protecting the core of the item lifted.
