ABSTRACT:
An apparatus specifically tailored to transporting pipes in a tunnel is disclosed. A pair of low slung bogies are used to support and transport a pipe to pipe junction location. The bogies move over a pair of rails on rollers. The pipe rests on a set of inflatable devices which may be selectively inflated in a controlled manner to move the pipe in two axes during transport to the junction site. At the junction site, the inflatable devices are used to "jockey" the pipe on the transport device to provide limited roll, pitch and yaw movement of the pipe to facilitate mating the transported pipe with the end of a previously set pipe string.
