Abstract: Apparatus and method for transporting and laying pipe segments or sections directly in a ditch dug for underground pipeline installation, minimizing use and size of right-of-way adjacent the ditch. The apparatus has a mobile unit with support configured to align weight of the pipe segments or sections with the longitudinal central axis of the mobile unit. Caterpillar tracks carry and move the apparatus, which can be controlled remotely. The apparatuses transport and lay pipe segments by cooperating in tandem formation while maintaining alignment of the weight of the cable with the longitudinal central axis of each of the mobile units.

Abstract: A programmable and remotely operated and controlled pipe laying apparatus and method of using it for transporting and laying pipe for a pipeline, that can receive, hold, transfer and/or transport and unload pipe in a ditch or other tight space otherwise requiring a side boom. The apparatus has a mobile platform with a longitudinal central axis. A support extends in an extensible manner from the mobile platform and aligns the weight of the pipe with that longitudinal central axis. A pipe holder is associated with the support to facilitate the receiving, holding, transferring and unloading of the pipe on the mobile platform. The apparatuses can cooperate and work in tandem to carry larger and heavier pipe than a single apparatus can handle.

Abstract: An apparatus and method for laying pipe in a ditch. The apparatus comprises a mobile platform having a longitudinal central axis. A support extends from the mobile platform and includes a cradle. The cradle supports a weight of a pipe segment in alignment with the central longitudinal axis of the mobile platform as the pipe laying apparatus transports the pipe segment to a location where the pipe segment is to be placed and as the pipe laying apparatus offloads the pipe segment at the location where the pipe segment is to be placed in the ditch.
