Core Components & Functionality
The WUXI ABK 40-Ton Fit Up Rotator is a precision-engineered system designed for large-diameter vessel fabrication, pipeline girth welding, and offshore structure assembly. Its robust configuration includes:
-
Driving roller frame with AC motor + reducer and frequency conversion control (0.1–1.2m/min adjustable speed)
-
Driven roller frame and hydraulic assembly rollers (2 sets) with 0.5mm alignment accuracy
-
Integrated hydraulic lifting and track movement for seamless cylinder butt-jointing
Workflow Efficiency
This industrial rotator streamlines pressure vessel welding and wind tower fabrication through a three-stage process:
-
Segmented Positioning: Place cylinders on driving/driven frames; align via hydraulic adjustment.
-
Assembly & Welding: Achieve precision fit-up (±0.5mm); weld inner/outer seams using welding manipulators.
-
Continuous Expansion: Repeat to complete large-scale container welding (1.5–6m diameter).
Technical Advantages
-
50-ton max load (customizable for heavy fabrication)
-
Stepless speed regulation for consistent weld quality
-
Anti-creep and anti-deflection mechanisms
-
Automated welding integration (compatible with robotic welding systems)
Safety & Compliance
-
Overload protection and emergency braking
-
ASME-compliant welding processes
-
CE/ISO certified for industrial safety
Wheel introduction
Polyurethane wheels offer exceptional abrasion resistance, versatile processing, wide applicability, and superior resistance to oil, ozone, aging, radiation, and low temperatures. They also provide strong adhesion, excellent sound transmission, biocompatibility, and blood compatibility.

Welding Rotator Maintenance Guidelines
Clean the welding rotator before use. Keep the rubber rollers away from oils and high temperatures to prevent aging. It’s recommended that a designated person operates and maintains the equipment.
Ensure the speed reducer is filled with 30# engine oil before starting, especially when the temperature is below 0ºC.
Replace the oil in the speed reducer after the first month of use. Afterward, change the oil every six months.
Do not use the roller bed as a welding ground to avoid damaging the bearings.
