This kind of equipment has B and C type. YF08B type is used for the overturning of H beam at 180 degrees for the purpose of welding another side of welding seam. YF08C type not only can overturn at 180 degrees but also can overturn at 90 degrees. YF08C type is mainly used in the processing of straightening the H beam. B or C type supports consists of 2 units equipments. When operating, it can adopt the way of overturning and moving at same time, to overturn the H beam to the seating ways they want. Using the Flow Divider/Combiner valve to adjust the flow of the 2 units of hydraulic cylinders to reach the purpose of running at synchronization. It has the features of running stable, reliable and convenient usage. That means YF08B type is before welding,YF08C type is before straightening.
