RD20-PV Redrock 20t Self Aligning Welding Rotator Set
The Redrock RD20-PV is engineered to automatically adjust to varying vessel diameters without manual wheel adjustments, making it a highly efficient solution for fabricating tanks, boilers, and pressure vessels.
Designed with industry-leading expertise, this self-aligning system is essential for professionals requiring absolute precision and maximum throughput in vessel, tank, and large-diameter pipe production.
This robust Drive/Idler set eliminates manual roller adjustment, automatically centring and gripping the work-piece to maintain a stable centre line throughout the welding process. This crucial feature drastically reduces setup time, minimises material handling risks, and ensures consistently perfect weld seams, even on out-of-round vessels.
With a 20-ton capacity and a 30-metric ton total rotation capacity, the RD20-PV is built to handle significant loads. Its advanced control system allows for exceptional precision, offering a variable roller speed range of 130 to 1300 mm/min (at 5 to 50Hz), ensuring suitability for complex automatic welding processes. This machine delivers reliability, superior performance, and demonstrable return on investment.
Features
- Maximises safety, precision, and efficiency during heavy-duty tank, pipe, and vessel fabrication.
- Self-Aligning Roller Mechanism: Pivoting wheel brackets automatically adjust to the vessel diameter. No manual pin adjustments are required.
- 4-Wheel Weight Distribution: Distributes the work-piece weight across four wheels per unit. This prevents the distortion of thin-walled vessels.
- Synchronised Dual-Motor Drive: The drive unit utilises two synchronised AC motors and gearboxes. This provides uniform torque and smooth, jerk-free rotation.
- Heavy-Duty Polyurethane Tyres: High-grade vulcanised PU wheels absorb shock, resist wear, and provide high traction without marring or slipping.
- Variable Frequency Drive (VFD): Inverter-controlled motors allow step-less, precision speed adjustments to match exact welding parameters.
- Robust Chassis Design: Fabricated from heavy-section steel plates to withstand harsh welding environments and high impact loads.
