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
|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.
||Need to set up a variety of protection devices, such as ELCB, Electrical fuse, and so on.
||1.Must be used international label.
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.
