• Summary

1. Equipment composition

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 assemblyund large-diameter pipe welding. This industrial rotator system combines variable frequency speed control, hydraulic lifting adjustmentund track-guided movement to streamline fit-up welding processes in pressure vessel manufacturing und structural steel fabrication.

Core Components & Workflow

The system comprises:

• Driving roller frame mit AC motor + reducer (0.1–1.2 m/min stepless speed regulation)

• Driven roller frame for stable rotation

• Hydraulic assembly roller frames (2 sets) mit 0.5mm precision alignment und track mobility

Operational Process:

1. Segmented Positioning: Place the first barrel on the driving/driven roller frames, and the second on hydraulic roller frames.

2. Assembly & Welding: The frames move along tracks for butt joint alignment; the hydraulic lifter fine-tunes position before tack welding. A Schweißmanipulator completes inner/outer seam welding.

3. Continuous Expansion: Repeat to assemble large-diameter vessels (1.5–6m) segment by segment.

Technical Advantages

• 50-ton max load (customizable for schwere Fabrikation)

• Hydraulic precision: ±0.5mm fit-up accuracy

• Automation-ready: Compatible with welding robots und manipulators

• Safety systems: Overload protection, emergency brakingund anti-skid limits

Applications

Ideal for:

• Pressure vessel und storage tank construction

• Wind tower und 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.

Motor introduction

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.
