Advantages of explosion proof double girder overhead crane

Why to select Explosion proof double girder overhead crane system? Explosion proof double girder overhead cranes systems are required in the hazardous environment to ensure in the safety of crane operation and working staff. Generally, they are widely used in chemical plants, gas power plants, paint shops, mining, oil refineries, and waste water treatment plants and other applications due to the following advantages and features :

• Reasonable design and strong explosion-proof capability.
• Good structure and good rigidity, reliable operation, excellent performance.
• Installation of adjusting speed converter, stable operation
• High safety and reliability, long services life.

If you neglect some of the potentially dangerous issues, you may lose a large number of people and money. There are also a lot of radioactive materials in the coal mines, which could cause harm to the workers. As a result, we can design an explosion-proof overhead crane exclusively for your coal mine.

There are two main types of explosion-proof cranes: single girder and double girder explosion proof cranes. To satisfy your specific requirements, a variety of capacities and sizes are available.

As the crane designers and manufacturers, the explosion proof overhead cane we provided can meet your lifting requirement at very reasonably price. If you need an explosion proof crane at economical price, please feel free to contact us to check what we can do for you to save your budget.
