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 the joint and corner seams to ensure the 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 a 1250t pre-bending press, to three roll bending machines, to the longitudinal seam of the cylinder. Hehuan automatic welding center welding and heavy-duty CNC horizontal lathe processing cylinder.

Attention:

Safety is the most important issue for cranes. To ensure safety, it is forbidden to use the equipment in flammable, explosive or corrosive environments. (Explosion-proof type is required for this).
