Large diameter travelling pipe cutter

Abstract:

According to an aspect of the present disclosure, a low profile travelling pipe cutter is provided which is adapted to perform at least one of cutting and beveling a hollow vessel while traveling around the vessel using a cutting tool mounted thereon. The pipe cutter includes inner and outer carriages, a capstan assembly attached to the outer carriage to which a feed cable is attached, and rollers attached to the outer carriage to which a tension cable is attached. The force adjustment assembly changes the vertical position of the outer carriage relative to the inner carriage to compensate for the pipe cutter going inwardly and outwardly as it travels around a hollow vessel in order to maintain constant pressure caused by the lever tension interface. A guard assembly is provided for covering and uncovering the cutting tool during cutting.
