Hydraulic Shell to Shell Fit-Up Rotators are specially designed to Align, Rotate and Support two sections of same diameter Shells for ‘Tack Welding’ or ‘Full Circumferential Seam Welding’.

1. Purpose: Used for shell to shell fit-up as part of wind tower production line and for heavy industrial equipment manufacturing process like pipes, pressure vessel, heat exchangers Welding etc.
2. linkage control interface, which can realize the linkage control with welding manipulator.
3. performance and characteristics
special polyurethane rollers able to handle the loads applied by conical towers.
High-torque gears and motors especially dimensioned for rotating even the heaviest tower sections
Rotation movements are smoothly and accurately controlled in all loading conditions by high quality invertersThe speed and direction are set by a controller.
