Abstract
A transporting device for lifting a relatively heavy roll of material to a selected level so that it can be moved and loaded onto production apparatus. The device comprises a platform base on casters that supports a fixed vertical, tubular column, within which is mounted an elongated, rotatable screw threadedly engaged to a ballscrew nut that moves up and down with the column when the screw is turned. Connected to the screw nut by a support assembly is a spindle that extends outwardly at a right angle from the column. The screw is driven by an electric motor mounted on the platform base, powered by the battery and connected through a gear reduction unit to the screw. A handle is attached to the platform base for moving the entire device and controllable switches are provided for moving the spindle up and down within preselected limits.
