发明名称 Roll lifting dollies
摘要 An assembly for facilitating the lifting and repositioning of heavy rolls of sheet material, such as carpet rolls and the like. First and second jack assemblies are mounted separately on two frames, each supported by two casters. The jacks have stubs of predetermined lengths which can be raised and lowered as the jack handle is manipulated. Extending between the stubs on each of the jack assemblies are a plurality of joined segments of pipe which pass through the center of the roll to be lifted. As the jacks are operated, the load is elevated from the floor to a desired height and, because the jack assemblies are on wheels, the load may be moved laterally as well. The frames on which the jack assemblies are mounted also include a plurality of upwardly extending stubs for facilitating self-storage of the plural pipe segments when they are not in use.
