  • Patent number: 8827338
    Abstract: A clamp and hoisting device serves the dual purpose of preventing a sleeve over a tubular or column like structure from sliding in an axial direction and also provides a connection point for a hoisting device. The device includes first and second arms composed of a plurality of arcuate links. Each arm is connected to an upper connector block and a lower connector block. The two arms are positioned over the tubular and the two lower connector blocks are secured to each other thereby forming a clamp. The upper connector block includes a connection point for attachment to a hoisting mechanism so that the clamp also serves as an attachment point for a hoisting mechanism.
