  • Patent number: 6840556
    Abstract: A device for maneuvering cylinders having first and second semi-circular lifting members hingedly connected to one another by first and second hinge members. The lifting members are urged toward one another and the cylinder to frictionally secure the lifting members against the cylinder for maneuvering of the cylinder. First and second free ends of the first lifting member are maintained in a spaced apart relationship relative to first and second free ends of the second lifting member corresponding to a desired gap distance, and the first and second hinge members of each lifting member each define a hinge point located a desired hinge distance vertically spaced from free edges of each of the lifting members, such that the ratio of the gap distance to the hinge distance is at least about 1.25.
