Appl. No.:

10/056195

Inventors:

Mark A. Herman - Landisville PA
Jeffrey R. Kauffman - Lancaster PA
Jeffrey M. Klibert - Lancaster PA

Assignee:

Lift-All Co., Inc. - Landisville PA

International Classification:

B66C 110

US Classification:

294 8212, 24116 R

Abstract:

The invention is a plate with three holes to function as a winch line attachment point and a length and angular adjustment for a chain attached to separated locations on a vehicle. One large hole is used to receive the winch line hook, and two smaller holes with angularly oriented chain locking slots are used to adjust the length of the chain attached to the towed vehicle. The material around the holes is reduced to the minimum size necessary to safely meet the rated towing capacity so that the weight of the plate is minimized.

Abstract:

The apparatus is an abrasion guard for the webbing used with a lifting sling fitting. The abrasion guard is essentially a rod of polyethylene with a slot along one entire longitudinal edge and extensions or "ears" on both ends of the rod. The extensions have vertical slots centered on their outside edges. The shape permits a properly dimensioned guard to be snapped onto and around the inner edge of the straight bar of a "D" ring fitting, with the extensions extending up along the sides of the "D" ring. The extensions are made large enough in the dimension transverse to the plane of the "D" ring so that they extend beyond the thickness of the webbing looped around the straight bar of the ring and the abrasion guard. The extensions thereby act as skids to protect the webbing from damage as the ring is moved across an abrasive surface.
