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.
Description:
- 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
-
Feature:
- Power rotator is double motor driven tow wheels with big &
balance torque output of max 1200t turning capacity
- 42CrMo fored steel wheel, made for heavy duty gaint
column/monopile.
- Hydraulic lifting idler with function of adjusting the workpiece
position, suitable for welding seam alignment, easy for
fitup/growing procedure.
- Motorized bogie moving along with the rail, realize ground logistic to decrease the hoist risk & make the
transportation easy.
- Highly boosting the working efficiency & improve the product
quality.
- Production according with mechanical standard JB/T 9187-1999.
Technical Parameter
| Equipment | 1200T welding roller rotator |
| Composed | 1drive unit + 3 hydrualic lift idler unit |
| Work load limit | 700t/power/idler rotator |
| Workpiece dia. range | ø3,000~ø10,000mm. |
| Wheel material | Forged Steel roller. |
| The distance between ground and rotator center | 1,850mm ( Return to zero point.) |
| Roller center moving distance and adjustment method | 1.The idler roller seat is fixed by bolts. 2.Adjust the center distance of the roller with bolt holes. 3.Roller seat moving distance is 150mm. |
| Rotator walking method | 1. One unit of rotator is electric walking and the other one is
unpowered walking. 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.
