The main components of the hanging roller machine are the hanging roller shaft and the steel mold. The reinforced concrete pipe is formed by the pressure and centrifugal force generated by the rotation of the steel mold and the hanging roller shaft, and then the strength of the pipe is enhanced by steam curing. The production of reinforced concrete pipes with a length of less than 2 meters and an inner diameter of 300mm-2000mm. The hanging roller machine has a short production cycle and high efficiency. It is easy to form concrete by laying the concrete directly on the hanging roller machine, and it only takes 3-5 minutes to quickly turn the root pipe.
