ABSTRACT:
A power assisted roll handling attachment for a lifting apparatus. Its support frame includes a gearmotor assembly and guides and is adapted for attachment to the lifting apparatus. A movable roll support assembly includes a support beam, a roll core mandrel assembly and a rack member having a curved portion. The rack member is adapted for being driven by a drive member carried on the output shaft of the gear motor. The support beam has a cross section defined by a flanged portion and a web portion. The support beam is formed in an L-shape having a first end, a second end and a radial portion formed therebetween. The rack member is positioned in a spaced parallel relationship with the flange portion. The roll support assembly is supported by the guides. Selective energizing of the gearmotor moves the roll support assembly with respect to the support frame thereby moving any roll of material carried by the roll support assembly from a first angular position to a second angular position by movement through the radial portion. Selective linear movement may be provided at the first end or second end.
