  • Patent number: 5205599
    Abstract: An auxiliary protective coil lifter saddle adapted to be mounted on an arm of a coil lifter for transporting a coil of material having an inner surface defining a core, the arm having a lifting segment with a lifting surface and two side walls depending therefrom. The auxiliary protective coil lifter saddle includes a frame and a pad. The frame has a body with at least two opposite ends and a plurality of lugs, wherein at least one of the lugs attaches to a respective end of the body. The body and the lugs have upper surfaces and lower surfaces. The pad attaches to the upper surface of the body and is made of a soft resilient material such as polyurethane, whereby a bottom surface of the body can be placed on the lifting surface of the arm and the lugs deform so that the lugs depend from the body. The respective bottom surfaces of the lugs abut against the lifting segment. Accordingly, the inner surface of the coil rests on an upper surface of the pad.
