Abstract: An end cap sleeve stretch sub-assembly for holding the ends of the sleeve portion of a spreader roller assembly being rotatable on a stationary shaft, including a pivot arm assembly for adjusting the angular displacement of the end cap assembly with respect to an axis of the shaft in order to expand and contract sections of the roller assembly resilient sleeve, an outer bearing ring and bearing assembly including a slide ring which is adapted for slidable adjustment parallel to an axis of the shaft on the outer bearing ring in order to preload the end cap sub-assembly by adjusting the tension on the sleeve, and a clamping assembly for securely attaching the sleeve portion to the outer slide ring.

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.
