Offshore Windmill 1200t Welding Roller Rotator 1Power 2Idler Hydraulic Fitup Growing Line




Brief introduction:


Welding roller rotator with turning capacity of 1200t/power rotator. 


1power rotator & 2 hydraulic idler rotator using for 1200t gaint column fitup/growing line. 


Mainly using for offshore wind mill monopile, also using for petrochemical column/refiner etc industries. 






  • 1200t welding roller rotator is composed by power rotator & hydraulic idler rotator.
  • Power rotator turning capacity is 1200t/pc. Each rotator working load limit is 700t/pc. 
  • Idler rotator wheels are hydraulic cylinder driven, via which extention/redraw to adjust the column position
  • With function of idler hydraulic jacking wheel, the monpile growing welding roller bed could aligning the sections to complete the fit up procedure.
  • The welding roller rotator is conventional type with reserved screw on pedestal to adjust wheel center distance, so as to fit for diverse diameter MP
  • Power welding roller rotator install with motorized bogie moving on the rail.  Idler welding rotator with idler bogie. 
  • Extention funciton of linkage control with other equipments, realize automatic welding of circumferential seam

2. When the roller bed is walking, the maximum load is 1000 tons.

3. A group of rotator can move on the track at full load.

4. Electric walking speed is 230mm ~2300 mm/min

Group pair lifting drive Hydraulic.
Hydraulic station

1.Independent hydraulic station for each rotator.

2.Each hydraulic cylinder is equipped with an independent oil pressure gauge, and there is a comparison table of pressure-convertible load, which is recorded in the manual.

Rotator control function

1.Low voltage (24V) wired (30M)/wireless remote control (100M).

2.Control cable length 30m, and must be provided a set control cable for spare parts.

3.The grounding of the electrical components of the control box must meet the electrical code requirements.

4.Cylinder lifting stroke and walking control.

5.Stop & E-stop button and synchronized function.

6.The remote control must have the above functions.

7.If the wireless remote control is damaged, it can use the wired control to operate.

8.Each hydraulic cylinder can operate independently and with linkage capability

Electronic control part

1.Hydraulic station and power control box need to be protected.

(windproof, dustproof, waterproof)

2.Electronic control box and elements

can be fast disassembled.

3.The electronic control box and

components need to adapt to the

subtropical & island-type climate.

4.Perfect protection circuit

(windproof, dustproof, waterproof).

Electronic components brand Schneider
Transmission & gap protection Windproof, dustproof, waterproof.
Rotator weight and lifting method

1.The weight of the rotator must be clearly marked on the drawing and sprayed on the rotator.

2.The rotator needs to provide and set the ideal lifting position and method and mark it on the drawing

Rotator stabilization and anti-roll device

1.Set holding track device, the design drawings must be provided and recorded in the manual.

2.A stable device in contact with the ground is required at the periphery of the rotator.

3.When the rotator is fully loaded and not moving, the rotator can be stabilized.

Linkage between rotator and welder If necessary, rotator manufacturer should open the roller bed system and cooperate with the welding manufacturer to integrate system.
Protective Need to set up a variety of protection devices, such as ELCB, Electrical fuse, and so on.
Maintenance spares 1.Must be used international label.
Paint requirements

1.All metal surfaces must be sandblasted

and painted to SSPC-Sa2.5.

2.Zinc primer coat 1 layer (75 μm / 1 layer) and finish coat 2 layer(250 μm / 2 layer).

3.Paint color: Green - RAL6011.

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.
