Product Description
250 MT Wind Towers Fit up Turning rotators for tank diameter 7500mm
Hydraulic Fit-up Turning Rolls are mainly used for cylinder assembly.
Each set of fit up rotators consists of a single-section cylinder assembly system, a rotary system, guide rails, a hydraulic system, an electrical control system, and an operating system.
How do Hydraulic Fit-up Turning Rolls work?
1.Hydraulic Fit-up Turning rotators use the hydraulic system to realize the adjustment of the up and down, left and right, front and back, and misalignment of the cylinder joints, and can perform precise stepless adjustments to the gap between the pair, the position of the welding joint, and the misalignment.
2.Each set of the hydraulic group roller frame is composed of two identical driven frames, and each driven roller frame is equipped with two sets of hydraulic cylinders to drive the roller assembly system, and the hydraulic cylinder is used to adjust the center distance of the roller assembly or to move a certain roller assembly. The roller rotators are used to align the workpiece.
3.The hydraulic system adopts a set of hydraulic pump station to uniformly supply oil to each hydraulic cylinder, and the hydraulic cylinders can be operated and controlled separately, and each hydraulic cylinder can independently drive a welding rotators roller assembly. 
Specifications:
Why more and more wind tower production lines choose automatic hydraulic team turning rotators?
1.Hydraulic fit up welding turning rolls can minimize the labor intensity of the assembly work, improve the assembly efficiency of the circular seam of the cylinder, and ensure the assembly quality.
2. The alignment station of barrel joint length includes one alignment machine and two alignment rotators.
The roller assembly installed on the upper part of the assembling machine can be applied to the cylinder section with a small length and can realize the rotary function. The other cylinder joint moves up and down, left and right to realize the pairing.
The use of Hydraulic fit up welding rotators improves the alignment accuracy of pipe or tank vessels.
