1. Crane wheels and axles have undergone high-frequency quenching and quenching and tempering treatment, which effectively eliminates internal stress and ensures machining accuracy.

2. The main beam plate mainly adopts radiographic inspection and ultrasonic inspection to weld joints and corner seams to ensure welding quality.

3. In the field of main beams, the first to adopt intelligent and efficient welding robots, the seam welding of the main beams adopts advanced MAG, the use of Ar+Co2 Mix shielding gas, and the outer side of the four main beams adopts submerged arc welding fillet welders.

4. Using rolled steel drums or seamless steel pipes, Henan Mining Crane Co., Ltd. has an industry-leading production and processing line for rolled steel drums, from 1250t pre-bending press, to three-roll bending machine, to the longitudinal seam and ring of the cylinder. Automatic welding center welding and heavy-duty CNC horizontal lathe processing cylinder.

Attention:

Safety is the most important issue for cranes. To ensure the safety,It is prohibited to use the equipment in the combustible, explosive or corrosives environment.(Need explosion proof type for this).
