Trolley rail is made of high strength hot rolled flat steel (16 Mn)

Epoxy zinc-rich painting for one bottoms and two sides of 120μm thick, to achieve a long lifespan, beautiful appearance and good luster

The girder and end beam are connected together by high strength bolts to ensure the structure strength and precision of the whole machine
The end beams are equipped with flat wheel or double rim wheels, anti-friction bearings, buffer blocks and derailment preventing end plate
Maintenance walkway is located on one side of the main girder, consisting of flower pattern plate, 1050meters handrail.

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.

7. The wheel and wheel axle and treating by high efficiency quenching and tempering, it can eliminate the internal stress effectively and ensure the processing precision,

The trolley frame, drum, and bogie frame and related big welding structure are treated by Annealing in the natural gas annealing furnace to ensure the Machining accuracy after welding. Henan Mine Crane Co,.LTD have car bottom  natural gas annealing furnace, the furnace chamber inside size (length*width*heigh) is 10000mmx4000mmx4000mm, this annealing furnace can satisfy the Stress-Relieving annealing treatment after welding for the trolley frame, drum, bogie frame, balance beam, spreader and all kinds of welding structure on the crane, Only Henan Mine Crane Co.,LTD  has this ability in China Crane Hometown.

8. As the top industrial crane manufacturers, Henan Mine Crane Co,.LTD has top advanced processing and manufacturing equipment and processing technology in the crane industry all over China, at the same time,Henan Mine Crane Co,.LTD take the head in achieve the best and better management, best and better manufacturing, Try the best to ensure the Henan Mine Crane Co,.LTD product quality and satisfy the demand of customer.
