30 tons Adjustable Height Positioner

30 tons Adjustable Height Positioner Parameter table

1.Slewing bearing

The slewing bearing is a critical load-bearing component that enables relative rotation between machine parts while simultaneously handling axial, radial, and overturning moment forces. Its compact and lightweight design, made from high-strength alloy steel, ensures smooth operation with high precision (±0.05° rotation accuracy) and long service life. Key configurations include mounting bolt holes, optional internal/external gears, lubrication ports, and sealing systems for enhanced reliability. With a diameter range of 300–5000mm and load capacity up to 50,000kN, it is widely used in construction machinery, wind turbines, cranes, and military equipment. Custom designs are available for specialized applications.

2. Gear

1). Reverse gear

Generally, the turning angle of the turning gear is 0 °to  90 °. The function of displacement is achieved by turning the table.

2). Reverse gear

Gears are toothed mechanical components that transmit torque through meshing engagement with other gear elements like racks, worms or additional gears, enabling precise control over power transmission by modifying speed/torque ratios, redirecting motion paths, and converting motion types (e.g., rotary to linear). Their interlocking teeth design provides reliable force transfer while allowing for customizable mechanical advantage in various industrial applications.

3.Reducer

Gear reducers are mechanical power transmission devices that utilize precision gear systems to reduce input speed while proportionally increasing output torque, with the output torque being the product of motor torque and gear ratio (without exceeding the reducer’s rated capacity). These systems simultaneously decrease load inertia by the square of the reduction ratio, enabling optimized power conversion for various industrial applications through efficient gear engagement.

Comprehensive Maintenance Protocol
Proper care of our 30-ton adjustable welding positioner ensures optimal performance in pressure vessel fabrication, structural steel welding, and heavy equipment manufacturing. Daily maintenance should include removal of welding slag deposits and verification of lubrication levels in all gear reducers, along with thorough electrical safety checks on control systems.

For regular maintenance cycles (recommended every 250 operating hours):
✓ Tighten all high-strength bolts to 90-110Nm torque specifications
✓ Inspect worm gear transmission components for wear
✓ Test emergency stop and overload protection functions

Annual Deep Maintenance requires:

• Replacement of wear-prone components (bearings, seals)

• Complete re-lubrication of all moving parts using Mobilith SHC 220 grease

• Full system recalibration to maintain ±0.5° positioning accuracy

Operational Safety Alerts
Immediately halt operation if detecting:
• Abnormal noise from drive systems (indicating potential gear damage)
• Uneven rotation (suggesting roller alignment issues)
• Electrical faults in the Siemens PLC control interface

Proven Maintenance Benefits
Our protocol delivers:
✓ 30% extended service life for industrial welding positioners
✓ 50% reduction in unplanned downtime
✓ Consistent welding precision (±0.2mm repeatability)

Certifications & Innovation
Every ABK adjustable positioner carries:

• CE & ISO 9001 certification for welding machinery

• Explosion-proof options (ATEX Zone 2 compliant)

• IoT-ready interfaces for smart factory integration
