L-Shaped Single Girder Gantry Crane

L-Shaped Legs Single Girder Gantry Crane with Winch is applied for handling and conveys operation outdoors, or stock ground, railway station, sea port cargo area, etc. L-Shaped Legs Single Girder Gantry Crane with Winch can be also used to do some special operations lifting large diameter and large length equipment.

Given certain lifting height, the overall height of L type gantry crane is reduced out of its structural features. As a result the cost is lowered.

M-Shaped Legs Single Girder Gantry Crane with Winch is featured by light deadweight, light wheel load and reliable performance.

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., LTDare 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.
