Portable Welding roller frame is a fixed applies Tube welding auxiliary equipment, which is driven by the drive roller frame and roller frame roller frame composed of two parts manufacturers, can be used for tube type, girth weld demand, simple, mobile Light is one of the ideal equipment for pipe welding process in class. 1, the diameter of the workpiece: φ100 ~ φ500mm 2, maximum workpiece weight: 1000Kg 3, wheel size: φ254 × 51mm 4, wheel line speed: 5580mm / min (maximum speed) Adjustable roller frame is through the initiative of the wheel and weldments friction between displacement drive rotating machinery weldments. Adjustable roller frame only one roller member is active roller member, and the other is a driven roller member. Drives are used in frequency conversion motor, speed reducer to drag the wheel through a small roller frame components and weldments do welding rotary drive. Each roller frame components of the wheel cylinder spacing adjustment welding roller stand, is by manually, according to the weldment, the use of positioning the bolt to complete.
