MANIPULATION AND TRANSPORT DEVICE FOR ROLLED MATERIALS

摘要

A device for the lifting, manipulation and transport of heavy rolls (10) of material from shipping containers to and from production apparatus is disclosed. The device has a mandrel (52) which grips rolled stock at the roll core (12) by means of expansion inside the roll core, and manipulates the rolled stock from its shipping position to a position suitable for placement on the mandrel of equipment to utilize the rolled stock. The device allows for transport of the rolled stock from shipping or storage locations to machinery for use. The device is capable of straddling shipping pallets (20) and the like to allow for positioning the mandrel over the rolled stock while maintaining a relatively low center of gravity. Attached to the vertical lift plate (30) is a second plate (32) which is capable of sideways movement of the rolled stock and the mandrel for horizontal positioning. Primary energy sources are provided by electrically powered hydraulics (72) or manually actuated hydraulics, winches, or lead screws.
