250 Tons Self Aligning Welding Rotator for Stable Rotation of Large Cylindrical Workpieces
HALDEN SAR 250 tons self aligning welding rotator is designed for pipes, containers, boilers, pressure vessels, oil tanks, storage tanks, and other large cylindrical workpieces. It supports assembling, burnishing, and welding operations, and can work together with column and boom systems and SAW systems for inside and outside girth and longitudinal welding.
Large Tanks and Pressure Vessels Require More Than Simple Rotation. They Need Stable Support, Controlled Speed, and Safe Load Handling.
A heavy-duty self aligning welding rotator reduces setup time, improves welding stability, lowers operator workload, and supports more efficient fabrication of large cylindrical workpieces.
Key Information Buyers Need Before Ordering a 250T Welding Rotator
Before selecting a self aligning welding rotator, buyers need to confirm maximum load, vessel diameter range, vessel length, workpiece material, welding process, rotation speed requirement, wheel material, column and boom integration, SAW system matching, and workshop layout.
Load and Diameter Range
The SAR 250 model supports up to 250 tons load capacity and a suitable workpiece range of 1800–8000mm, making it suitable for large tanks and vessels.
Self-Aligning Operation
The self-aligning design helps the turning rolls automatically adapt to different vessel diameters within the rated range, reducing setup time and simplifying operation.
Welding System Integration
The rotator can be used together with column and boom systems and submerged arc welding systems for internal and external girth welding and longitudinal welding.
Speed and Control
Variable rotation speed from 100 to 1000mm/min and remote control operation help operators adjust welding speed, forward/reverse rotation, and stop functions.
