The three-wheel tube rolling machine is a specialized piece of equipment designed primarily for bending large arcs in metal tubing. This machine is relatively lightweight compared to other heavy-duty bending machines, making it easier to transport and operate in various settings.

One of the key features of this machine is its ability to adjust the arc size, which is achieved through the precise rotation and propulsion of a hydraulic motor. This hydraulic system allows for smooth and controlled bending, enabling operators to create arcs of varying dimensions according to specific project requirements.
