WUXI ABK 20-Ton Fit Up Rotator Product Introduction
The WUXI ABK 20-Ton Fit Up Rotator is a precision-engineered welding positioning system designed for cylindrical vessel fabrication, tank segment assembly, and large-diameter pipe welding. This industrial rotator system combines variable frequency speed control, hydraulic lifting adjustment, and track-guided movement to streamline fit-up welding processes in pressure vessel manufacturing and structural steel fabrication.
Core Components & Workflow
The system comprises:
-
Driving roller frame with AC motor + reducer (0.1–1.2 m/min stepless speed regulation)
-
Driven roller frame for stable rotation
-
Hydraulic assembly roller frames (2 sets) with 0.5mm precision alignment and track mobility
Operational Process:
-
Segmented Positioning: Place the first barrel on the driving/driven roller frames, and the second on hydraulic roller frames.
-
Assembly & Welding: The frames move along tracks for butt joint alignment; the hydraulic lifter fine-tunes position before tack welding. A welding manipulator completes inner/outer seam welding.
-
Continuous Expansion: Repeat to assemble large-diameter vessels (1.5–6m) segment by segment.
Technical Advantages
-
50-ton max load (customizable for heavy fabrication)
-
Hydraulic precision: ±0.5mm fit-up accuracy
-
Automation-ready: Compatible with welding robots and manipulators
-
Safety systems: Overload protection, emergency braking, and anti-skid limits
Applications
Ideal for:
-
Pressure vessel and storage tank construction
-
Wind tower and offshore platform fabrication
-
Pipeline girth welding
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.
