    • 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.
    • 用于提升和移动重的细长卷材料的装置包括适于轴向插入材料卷的细长构件,一对用于接合从辊的相对端突出的轴向构件的端部的提升装置。 每个提升装置具有固定到刚性框架结构的发散构件的支点构件。 用于接合轴向构件的一个端部的保持器固定到一个发散框架构件,并且可调节杆臂附接到另一发散框架构件。 用于在初始提升之后支撑材料卷的可移动台车具有可由提升装置接合的侧突出臂,使得当具有一卷材料的台车提升到预定高度时,材料可以在小车端轴向移动 到另一个表面。
