Abstract
Apparatus is described for transporting sections of pipe and connecting them together for laying pipe above ground or in a trench. The apparatus includes a wheeled frame (e.g., a trailer), rotary support for supporting one end of a first pipe section, and an alignment mechanism for supporting the other end of the first pipe section and the leading end of a second pipe section. The first pipe section can be rotated relative to the second pipe section to either connect or disconnect the pipe sections. In another embodiment, apparatus is provided for supporting pipe sections which are to be welded together.
