ABSTRACT:
An improved mobile pipe forming apparatus in which pipe forming apparatus is supported on a carriage. The carriage is mounted on a forward and a rearward pair of tracks, the two tracks of each pair being attached to each other by a rigid carbody, the carbody of one of these pairs of tracks being pivotally secured to the carriage by means of a ball and socket centered with respect to that carbody, the other carbody being secured to the carriage by means of a turntable which rotates above an axis normal to the surface of the carriage on a centered axis pin so that, during movement, the carriage stays on the same plane as that of the turntable. It is preferred that independent motors are provided for each track to power these motors. The motors are computer controlled. Other mechanical improvements over prior art mobile pipe forming apparatus are also described.
