Gantry Crane

Container rubber tire gantry crane with hooks is applied outside warehouse or railway sideways to do common lifting and unloading works. This kind of crane is composed of bridge, supporting legs, crane travelling organ, trolley with strong lifting winch, electric equipment and control system. As its heavy duty design, it can be widely used in all kinds of industrial field.

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, Henan Mine Crane CO., LTD 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.                        

4. 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, Henan Mine Crane CO., LTD 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.
