Hengtong Petroleum Machinery, committed to providing the ultimate solution for heavy-duty manufacturing, has launched a new generation of intelligent adjustable roller frames. This product transcends the fixed nature of traditional roller frames, integrating active travel, infinitely adjustable width, and intelligent control. Designed specifically to address the comprehensive welding and assembly challenges of extremely long, large, and heavy workpieces, it is a vital tool for the fabrication of large pressure vessels, energy equipment, and offshore structures.

Product Advantage
1. Active Travel, Unleashing Productivity
Our Adjustable Welding Rotator base is equipped with a high-power drive motor and precision reducer, enabling smooth, straight travel on pre-laid tracks.
Easy and convenient operation increases assembly efficiency several times.
2. Electric Width Adjustment, Multi-Purpose Machine
The width between the rollers can be precisely and continuously adjusted via a motorized mechanism.
A single device can perfectly accommodate a wide range of pipe and cylinder diameters, from Φ300mm to Φ4000mm (or larger, customizable), significantly improving equipment utilization and return on investment, eliminating the need to purchase multiple specialized devices for different products.
3. Intelligent Linkage, Precise Synchronization
Our Special Automatic Welding Rotator utilizes an advanced variable frequency control system, enabling not only stepless speed adjustment for each unit but also perfect synchronization between the master and slave roller frames, and between travel and rotation.
Optional linkage with a welding manipulator and welding power source enables coordinated control of welding process parameters (e.g., "torch on top, automatic travel"), laying a solid foundation for automated welding.
4. Heavy-Duty Design, Reliable Quality
Inheriting Wuxi Hengtong's heavy-duty heritage, key components are manufactured from high-quality alloy steel, rollers are surface-hardened (or coated with high-wear-resistant polyurethane), and the drive system utilizes a hardened gearbox, ensuring smooth operation and durability even under maximum loads.
Application Scenarios
The Self-Propelled Adjustable Turning Roll revolutionizes traditional manufacturing processes.
Extremely Long Pipe Welding: When welding pipes tens of meters long, the machine can continuously move the workpiece forward, enabling continuous and efficient welding of circumferential seams on extremely long pipes.
Large Pressure Vessel Assembly: When assembling multi-section cylinders, the travel function easily moves the weld to the most comfortable position, eliminating the need for repeated lifting.
Ship Block Manufacturing: When assembling ship sections, the machine precisely moves large sections, achieving millimeter-level alignment.
Wind Turbine Towers and Bridge Structures: It provides efficient rotation and movement support for welding longitudinal and circumferential seams on large steel structures.
