Modular Design
The component of crane are designed into various series standard modulars. And different modulars can be assemblied to different products.
All the modular components can assembly and disassembly 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
Both side of all the steel plates of crane are pretreated by pretreatment production line, Sand blasting-- Primer spray--Primer drying. Eliminate the inner stress of steel plate, increase the adhesive force of the steel structure. Ensure the appearance and anticorrosion quality.
Steel plate cutting adopts whole sets Messer CNC plasma cutting machine from Germany, with very fast cutting speed, little deformation, high precision, deviation could be controled within 1mm, it ensure the raw material at high quality standard and can reach top level in the industry.
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, adapt 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.
