Abstract
An apparatus for lifting pipe including an arm having a substantially rectangular cross-section, and a substantially cylindrical body portion pivotally mounted to the arm. The apparatus is designed to be inserted into the standard lift port of a pipe section. In addition, a handle may be attached to the arm to more easily carry and to guide the apparatus into the lifting port. The apparatus allows a single worker to quickly and efficiently lift pipe sections, while reducing the possibility of injury.
