Abstract
A coil edge protecting coil lifter and insert. The insert mounts within a cavity through an aperture in the front wall of each lifter arm of the coil lifter. The edges of a coil contact with a protruding portion of an endless belt which extends through the aperture and outwardly beyond each front wall. A low-friction wear plate atop a backing plate is positioned behind the endless belt and causes the belt to protrude outwardly. The endless belt can be made to additionally protrude through an aperture in the rear wall of each lifter arm.
Claims13
A coil lifter adapted to lift a coil having a coil core, said lifter comprising:
- an upper housing adapted to be suspended over a coil of material;
- a pair of spaced lifter arms connected to and extending downwardly from said housing, each of said lifter arms having a front wall opposed to each other and a lifting surface at a lower end of each arm adapted to fit within a coil core;
- means for effecting movement of said arms relative to each other to open and close said arms about a coil;
- and means at said front wall of each arm for contacting the edges of a coil located between the front walls of said lifter arms, each of said contact means being movable along with the edges of a coil relative to the lifter arm on which the contact means is mounted,
- whereby forces exerted on the edges of a coil as said front walls of said lifter arms are moved along said coil edges are minimized to minimize damage to the coil edges.
A coil edge protection insert adapted to be mounted within a cavity in a lower end of each lifter arm of a coil lifter, said insert comprising:
- a pair of spaced side plates;
- a pair of spaced belt guide rollers positioned between said side plates and rotatably mounted thereto;
- an endless belt positioned around and engaged with said guide rollers;
- and
- means for causing an outer surface of said belt to protrude a distance outwardly beyond a first side of a straight path of said path between said guide rollers.
