Device and method for laying and joining pipe

Image Number 13 for United States Patent #7261493.

A pipe installation device and a method for laying consecutive lengths of bell and spigot pipe. The pipe installation device installs sequential pipe lengths. The pipe installation device includes a pipe supply system and a pipe alignment system attached to a carriage. The pipe alignment system is positioned to receive a pipe length from the pipe supply system and align the pipe length with a pipe length previously positioned in the pipe alignment system. The pipe installation device also includes a pipe joining system for joining the two pipe lengths positioned in the pipe alignment system. A pipe restraint system applies a restraining force against one pipe length while the pipe joining system joins the two pipe lengths.
