Bolt Adjustable Self Centering Rotator Rubber Wheel Pipe Welding Rotator

Rubber Wheel Heavy SAR Rotators 300T Bolt Adjustable Self Aligned Welding Turning Roller Bed

Brief introduction:

“Self-Centering Rotator” are required for applications where the diameter of the job to be manipulated are of different sizes and varies time to time. Hence with this Rotators huge amount of time can be saved as the diameter is manually adjusted by the lead screw arrangement. “Self-Centering Rotators” are featured with Torque-free axle shaft that implies easy maintenance and easy replacement of worn out wheels. In a Self Centering Rotator, as the wheel distance adjustment is infinitely variable, optimum work-piece position can be attained. A Self Centering Rotator makes it possible, the alignment of shells in a vertical plane.

Feature:

• SAR Cradle structure on the central distance adjustable pedestal.
   
• Fit for larger diameter vessel by adjustable central distance.
   
• SAR type welding rotator is with more balance loading compare with 4pcs wheels of conventional welding turning rolls.
   
• Highly improve the vessel deformation situation by self aligned cradle structure.
   
• For standard 300t work load capacity(1power & 1idler), each cradle with 2pcs wheels, total 8pcs .
   
• Polyurethane wheel protect the vessel surface from rotation mark, and also avoid slip during rotating.

Main Technical Parameters:

Standard equipment:

• Robust fabricated all steel frames with 4 wheels for each section (steel-core with polyurethane tyres);
   
• Central distance step adjustable machining pedestal for SAR turning roller interval distance adjustment; 
   
• Drive with AC-motor;
   
• Variable rotation speed;
   
• High and constant torque;
   
• Main cable with plug;
   
• Remote control with cable 6m;

Remote controller functions:

• Forward/stop/reverse
• Rotation speed
• Driving vehicle forward/stop/reverse (option driving vehicle DV-MO)
• Emergency-stop

Description:

• The bolt adjustable SAR welding turning roller bed can rotate vessel diameter range from 1000mm to 7500mm.
   
• Robust design with durable rollers.
   
• Cast steel gearbox with double worm gear arrangement for smooth operation and minimum backlash.
   
• Self aligned welding turning roller seat with cradle structure of 2wheels each. More contacting point with the turning roll job, effectively decrease the deformation situation. 
   
• Bolt adjusting pedestal step adjustable. By changing the cradle central distance, it could suitable for larger diameter tank compare with usual SAR welding rotators. 
   
• Power rotator wheels are driven with AC variable frequency drives and the motor providing a large range of rotation speeds
   
• Specially formulated high-load polyurethane tire design for high wear resistance.
   
• Solid state inverter for precise speed control.
   
• Hand-held operator pendants are standard, and optional foot switch controls are available.

Points you may concern:
 
Customization - Can your machine or other products be customized?
Ronniewell: Sure. As a professional manufacturer, we have our own engineer team, who is good at design, develop & build special solution catering for your individual requirement.
 
Transportation-What about the transportation?
Ronniewell: Seaway is the most common transportation way for oversea trading. Depends on your location, combined transport by rail and sea is also an option. Certainly railway transportation is also acceptable if it is the most suitable approach.
 
After sale service - What about the after-sale service?
Ronniewell: We provide 12month guaranty period for the whole machine quality. During this time, any issue proved because of the machine flaw itself,we would take the whole responsibility of it. Except of the guaranty period,technical advisory support is available freely covering the whole using life of the machine. Engineer service on user premises is also available for necessary.
