Hydraulic Fit up Rotators
“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”.
Construction and Technical Details of Hydraulic Rotators
Fit-Up Rotators have Four Units, Two Units (1No. Drive Unit + 1No. Idler Unit) are with Trolley Wheels and the other Two are Hydraulic Fit Up Units Fixed Base Type.
The trolley of the Drive Unit has an inbuilt drive system, so that the shell section supported on them can be moved forward or backward, in order to butt the shell edge, against the edge of the other shell on the fixed units.
Hydraulic Fit up Rotators Features:
- Both sections have a free multi-dimensional adjustment capability.
- The adjustment work is more flexible and can better accommodate different types of welding seam status
- The hydraulic V-wheel facilitates the axial movement of the tower
- It could greatly improve the working efficiency for thin wall thickness and large pipe diameter production
- Hydraulic Fit up rotator consists of a 3D adjustable shift rotator, a hydraulic working station with effective control
- Rotator base is made of welded plate, with a higher strength to ensure no curvature occurs over a period of time
- Rotator base & boring is an embedded process to ensure precise rotation of the roller
