Both lower rollers can rotate actively and move along the horizontal direction, upper roller can go up and down with two types of mechanical and hydraulic drive; the drive shaft usually connect to universal coupling, in which upper roller lifting and lower roller horizontal displacement are equipped with digital display. With pre-bending abilities, one-time loading plate material can be rolled to the required barrel type or arc type, if adding special device it can bend cone parts. it can also be equipped with digital display device, its control system set a man-machine dialogue, real-time monitoring，outage memory and safe protection etc. intelligent functions. At present, it is widely used in refined oil, chemical, boiler, steel structure, mechanical manufacture and other industries manufacturing all kinds of cylinders. Technical parameters Model Max.
