Pipe Welding Used Self-aligned Welding Rotator For Upto 20t Circlular Job
Feature of self aligned welding rotator:
- Robust design with durable rollers.
- Gritblasted steelwork with polyurethane finished coating to endure the abrasive environment of offshore and marine industries.
- Oversized bearings.
- Specially formulated high-load polyurethane tire design for high wear resistance.
- Cast steel gearbox with double worm gear arrangement for smooth operation and minimum backlash.
- Solid state inverter for precise speed control.
- Motorized and idler rail bogie versions available
Detail description of self aligned welding rotator:
- Self aligned welding rotators adjust the wheel centerline setting automatically when the vessel is lowered into place. There are no couplings to change and no pins to remove or replace.
- It provides constant centerline capabilities which make set-up and alignment quick and easy.
- The self-aligned welding rotator can rotate work pieces with diameters between 500mm and 3500mm without adjustment or change of drive shafts.
- Rolls are powered with AC variable frequency drives and the motors provide motors providing a large range of rotation speeds.
- Hand-held operator pendants are standard, and optional foot switch controls are available.
- The automatically infinitely adjustable centerline settings provide easy alignment for tapered vessels.
- The added surface area of 4 wheels per unit provides additional support for thin walled vessels.
Self-aligned welding rotator function:
- Forward/stop/reverse
- Rotation speed
- Driving vehicle forward/stop/reverse
- Emergency-stop
