ABSTRACT:
An apparatus is disclosed which is used to assist in lifting and moving storage tanks, pipes and the like. The apparatus includes a tubularly-shaped body suspended from a cable, the tubularly shaped body having a slot which communicates with the hollow interior of the tube allowing the cable to radially enter and exit approximately one-half of the hollow interior of the tube. The tube is inserted into an access port in the tank to be lifted and is positioned to engage the interior of the tank. The interaction of the slotted tube with the cable provides a convenient tool for engaging, securing and lifting the tank.
