Product Category : Gantry Crane

About the main beam and support leg, there are two types: box type and truss type, box type is good techniques and easy fabrication, truss type is light in dead weight and strong in wind resistance. . The complete machine features light dead weight, simple structure and easy installation and maintenance and widely used.

If you will use it in the environment with inflammable, explosive and corrosive gas, please let me know, we will equip the crane with corresponding measures.

There are three control way for your chosen: ground handle, wireless remote control and cab.

1. 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.

 

2. Steel plate cutting adapt whole sets Messer CNC plasma cutting machine from Germany, 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.

 

3. The welding of main beam adapt high efficiency and intelligent welding robot, Weihua are No.1 enterprise who adapt this high technology machine. The welding joint inside of the main beam adapt advanced MAG welding, adapt Ar+CO2 mixed protective gas, The 4 welding joint outside of the main beam adapt automatic submerged-arc fillet welding machine.

The welding of main beam adapt radiographic inspection and ultrasonic flaw detection for the welding joint and fillet weld position

5. The welding of end beam adapt double gun gantry submerged arc welding, highly welding quality ensure the stable quality of the crane effectively.

6. Adapt the steel plate rolling drum and wireless steel tube, Weihua has a set of steel plate rolling drum producing and processing line which is industry-leading level. From pre-bending by 1250t press machine, to Edge rolling by three-roller plate roll, at last the longitudinal joint and circumferential joint of drum are welded by automatic welding center and drum processed by heavy duty CNC horizontal machine tool.
