Pipe lifting tongs are utilized for lifting cylindrical sections of pipe, where the pipe sections may have different diameters but the jaw assemblies of the lifting tongs do not need to be changed out. The lifting tongs comprise first and second jaw members, where each jaw member may match the other. The jaw members comprise interiorally facing arcuate gripping members. The jaw members are pivotally connected together with a central fastener. Each jaw member comprises a mounting member rigidly joined to its respective gripping member. The mounting member may comprise a pair of parallel plate members, where a spaced defined between the parallel plate members. Each plate member comprises a plurality of apertures, including both circular and slotted apertures. When the first and second opposing jaw members are pivotally connected together, the parallel plate members may be sandwiched together, such that many of the apertures in the parallel plate members are aligned. The lifting tongs may be adjusted to fit different pipe diameters by changing the apertures which are utilized.
