High Quality Material and Components
The steel plates are all from Bao steel, Wuhan steel, Handan steel, all steel should be inspected by our National Technology Test Laboratory to ensure the quality.
The generator unit is International brand and the driving, rotating, hydraulic power unit are chinese or international famous brand.
Modular Design
The components of crane are designed into various series standard modulars. And different modulars can be assemblies to different products.
All the modular components can assemble and disassemble for good transportation.
Standard modular components can be manufactured with short producing time and steady quality. So that we can short the delivery time.
Advanced Manufacturing Technology
Pretreat
Both side of all the steel plate of crane are pretreatment by pretreatment production line, Sand blasting-- Primer spray--Primer drying. Eliminate the innerstress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and anticorrosion quality.
Cutting
Steel plate cutting adopts whole sets Messer CNC plasma cutting machine from Germany, wiht very fast cutting speed, little deformation, High precision, Deviation could be controlled within 1mm, it insure the raw material at high quality standard and can reach top level in the industry.
Welding
The welding of main beam adopts high efficiency and intelligent welding robot, Weihua are No.1 enterprise who adopts this high technology machine. The welding joint inside of the main beam adopts advanced MAG welding, adopts Ar+CO2 mixed protective gas, The 4 welding joint outside of the main beam adopts automatic submerged-arc fillet welding machine. The welding of main beam adopts radiographic inspection and ultrasonic flaw detection for the welding joint and fillet weld position.
