Self Alignment Seam Welding Turning Rolls For Tower Tank Pipe

Self Alignment Seam Welding Turning Rolls For Tower Tank Pipe

 Brief introduction:

Self aligned seam welding rotator is mainly used for circular weldment seam welding, such as wind tower, bridge pile, oil tank, vessel and so on.

Self aligned seam welding rotator feature:

• Self aligned seam welding rotators can roll different sizes of weldments without changing the wheel center.
   
• Rotator units for constant rotating and positioning of weldments, specially for circular job welding applications.
   
• Constant rotating and welding speed provides perfect welding results.
   
• Motorized trolley provides the rotator ability to travel on the rail, so as to fit for various length weldments requirement.

Standard equipment:

• Robust fabricated all steel frames with 4 wheels for each section (steel-corewith polyurethane tyres);
   
• Drive with AC-motor;
   
• Variable rotation speed;
   
• High and constant torque;
   
• Main cable with plug;
   
• Wireless remote control;
   
• Power unit with motorzied trolly

Functions:

• Forward/stop/reverse;
• Rotation speed;
• Power unit travel on the rail;
• Emergency-stop;

Main Technical Parameters

Detail description of self aligned seam welding rotator:
 

• The self-aligned seam welding rotators can rotate work pieces with diameters as small as 850mm and as large as 5000mm without adjustment or change of drive shafts. 
   
• Self aligned seam 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.
   
• Self aligned seam welding rotator provides constant centerline capabilities which make set-up and alignment quick and easy.
  
   
• 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.
   
• Robust design with durable rollers.
  
   
• 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.
