An apparatus for lifting and moving heavy, elongated rolls of material comprises an elongated member adapted to be inserted axially in a roll of material, a pair of lifting devices for engaging end portions of the axial member that project from opposite ends of the roll. Each lifting device has a fulcrum member fixed to divergent members of a rigid frame structure. A holder for engaging one end portion of the axial member is fixed to one diverging frame member and an adjustable lever arm is attached to the other diverging frame member. A moveable dolly for supporting the roll of material after initial lifting has side projecting arms which can be engaged by the lifting devices so that when the dolly with a roll of material is lifted to a predetermined height the material can be moved axially on the dolly end onto another surface.

An apparatus for lifting a heavy, elongated roll of material so as to maneuver it onto a surface above ground level, comprising: an elongated beam means adapted for insertion axially within said roll so that end portions of said beam means extend from each end of said roll; a pair of lifting means for engaging each said end portion of said roll, each said lifting means comprising a fulcrum means, a pair of first and second rigid members attached to and extending divergently from said fulcrum means, a holder means attached to the end of said first member for engaging one extending end portion of said beam means; a lever arm means having an extended length and attached to said second rigid member; whereby with said beam means inserted in said roll of material and with said holder means engaging said extending end portions of said beam means, force applied to said lever arm means will cause said holder means to move about said fulcrum means and thereby raise said roll of material from the ground; said apparatus further including in combination a generally rectangular platform means for supporting the roll of material after it has been lifted from the ground level; and extended transverse side members projecting outwardly from said platform and adapted to be engaged by said holder means of said lifting means.
