摘要： According to an aspect of the present disclosure, a low profile travelling pipe cutter (100) is provided which is adapted to perform at least one of cutting and beveling a hollow vessel (120) while traveling around the vessel using a cutting tool (120, 270) mounted thereon. The pipe cutter includes inner and outer carriages, a capstan assembly (130) attached to the outer carriage (138) to which a feed cable (252) is attached, and rollers attached to the outer carriage (138) to which a tension cable (250) is attached. The force adjustment assembly (140) changes the vertical position of the outer carriage (138) relative to the inner carriage (134, 136) to compensate for the pipe cutter going inwardly and outwardly as it travels around a hollow vessel (120) in order to maintain constant pressure caused by the lever tension interface (1307). A guard assembly (134) is provided for covering and uncovering the cutting tool (120, 270) during cutting.

摘要： Pipe machining apparatuses, such as traveling pipe cutters, are provided. One such pipe machining apparatus may cut or bevel a hollow vessel while traveling around the vessel, and include a frame including a top end and a bottom end with the bottom end adjacent an outer surface of the vessel. The apparatus also includes a cable wrapped around the vessel and a pair of rollers coupled to the frame with each roller defining a groove therein for receiving the cable. Each roller rotates about an axis that extends generally parallel to a central longitudinal axis of the vessel. The cable is positioned in each groove of the pair of rollers and each axis is positioned between the cable and the outer surface of the vessel. The cable is tensioned to provide a force on the frame in a direction toward the outer surface of the vessel.
