A new and improved pipeline coupling apparatus is disclosed. This apparatus incorporates an elongate support member having the form of an I-beam where the flanges of the I-beam serve as a guide for a traveling carriage. The traveling carriage is urged along the I-beam by means of a hydraulic cylinder and piston rod. The traveling carriage centers a pipe. It positions the coupling and forces the pipe into the coupling. The coupling itself is supported for sliding movement by a free moving carriage beneath the I-beam.
