Our company produces the only certified clean explosion-proof fully automatic crane in China, holding 16 authorized patents. It is the only company with a production qualification for such cranes. The crane features advanced technologies, including:

• High-seal explosion-proof drive mechanism

• Self-lubricating bearings for maintenance-free operation

• Compact design integrating motors, reducers, brakes, and electrical monitoring systems.

  
  

The new double-hoist explosion-proof crane, one of the largest in China, is widely used in the aerospace industry. It consists of two 160-ton hoist units, a heavy-duty bridge frame, and a three-in-one drive. The double hoists can lift and lower in sync, enabling simultaneous lifting and workpiece rotation. Its explosion-proof rating is DIICT4, and it complies with both GB National Standards and FEM European Standards. The crane uses hard-tooth surface reducers, variable frequency drives, and multiple safety protections. It is designed for high efficiency, low energy consumption, and minimal environmental impact.

This crane can be used in any hazardous environment requiring explosion-proof or other high-safety features. It is commonly applied in water, chemical, oil, gas, pharmaceutical, and food industries.

The explosion-proof crane is made from special materials and structures that effectively prevent static electricity, sparks, and other factors that could lead to explosions.
