Fixed Self-aligned Welding Rotator Tank Pipe Rollers for Welding
Brief introduction:
Self aligned welding rotators can roll different sizes of welding
pieces without changing the wheel center.
Detail description of welding rotator:
- Self-aligned welding rotator 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.
- Self-aligned welding rotator provides constant centerline
capabilities which make set-up and alignment quick and easy.
- The self-aligned tank turning roll can rotate work pieces with
diameters as small as 500mm and as large as 3500mm without
adjustment or change of drive shafts.
- Self aligned welding rotators are available in 5 ton to 300 ton
capacity.
- 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, while the added surface area of
4 wheels per unit provides additional support for thin walled
vessels.
Self aligned welding rotator feature:
- 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.
- Inverter for precise speed control.
- Motorized and idler rail bogie versions available.
- Ideal for:
- Wind tower fabrication
- Offshore and shipyards
- Pressure vessels
- Thin-wall vessels / Pipes
