WUXI ABK 20-Ton Adjustable Height Positioner Product Introduction
Technical Features
The WUXI ABK 20-Ton Adjustable Height Positioner is designed for precision welding automation in pressure vessel fabrication, wind tower production, and shipbuilding applications. Its heavy-duty frame features box-type steel construction for optimal load distribution, ensuring stability during large-diameter pipe welding and structural steel fabrication. The precision sliding track maintains ±0.1mm positioning accuracy, supported by a quick-lock mechanism for stable fixation during industrial welding processes.
Core Components and Performance
High-performance rollers constructed from ZG45 cast steel with HRC 55-60 hardness provide 30-ton dynamic load capacity, suitable for heavy workpiece rotation in offshore platform construction and energy equipment manufacturing. The dual-motor drive system (2×7.5kW) with frequency converter control (0.5-5 RPM) ensures smooth operation, while torque synchronization (±2%) guarantees consistent weld quality. The anti-creep mechanism includes hydraulic elevation adjustment (±50mm range) and automatic centerline alignment, achieving <0.5mm deviation for high-precision welding applications.
Advanced Control and Measurement
The positioner incorporates German NOVO displacement sensors with 0.01mm resolution and ±0.05% linearity, delivering exceptional accuracy for LNG tank welding and petrochemical vessel fabrication. The Siemens/ABB PLC control system with IP65 protection rating features an axial movement monitoring interface, enabling seamless integration with robotic welding cells and automated production lines.

Maintenance of Welding Rotator
1. This welding rotator needs cleaning before putting into use. And to avoid aging, the rubber rollers should stay away from oils and high temperature. If possible, there should be a specific person to operate and maintain this device.
2. Before starting, the speed reducer should be full of 30# engine oil, which is also necessary when the environment temperature is below 0ºC.
3. The oil inside the speed reducer should be completely replaced after the use of first month, and later, the engine oil can be changed every six months.
4. The roller bed can not be used as the welding ground so that bearings can be prevented from damaging.
Features of Welding Rotator
- The rollers’ distance automatically adjusts to accommodate different barrel diameters.
Speed is adjustable via a frequency control system, enhancing operational reliability.
3.Easy operation is ensured with a manual control box.
4.Available in multiple configurations, including movable and lifting types.
5.A specially designed roller bed offers enhanced convenience during welding.
6.Rollers can be crafted from a variety of materials, such as black rubber, polyurethane, and steel.

WUXI ABK 20-Ton Adjustable Height Welding Positioner Maintenance & Service Guide
Proper maintenance ensures optimal performance of your industrial welding positioner in pressure vessel fabrication, structural steel welding, and wind tower production. Before operation, thoroughly clean the adjustable height positioner, paying special attention to rubber rollers which must be protected from oil contamination and temperatures exceeding 60°C to prevent premature aging. We recommend assigning certified personnel for all welding automation equipment operations.
Critical Maintenance Procedures
-
Lubrication: Fill the speed reducer with 30# engine oil (ISO VG 150 equivalent) before initial startup. In sub-zero conditions (<0ºC), use winter-grade synthetic oil.
-
Oil Change Schedule:
-
First replacement after 30 days of operation
-
Subsequent changes every 500 operating hours or 6 months
-
-
Grounding Safety: Never use the rotator bed as welding ground – always employ separate grounding clamps to protect precision bearings.
