The explosion-proof double girder bridge crane is designed and manufactured to withstand explosions. Built on the foundation of standard bridge cranes, it is equipped with explosion-proof motors and electrical explosion proof components, along with other auxiliary mechanical explosion-proof measures, to ensure that the explosion-proof double girder overhead crane does not cause fires, explosions, or other hazards when operating in explosive environments. The explosion-proof mark is Ex.

All components of the explosion-proof double girder overhead crane are carefully selected for use in hazardous environments such as military handling, painting workshops, mining, chemical plants, petrochemical plants, refineries, gas-fired power plants, wastewater treatment facilities, and spray painting workshops.

Features of Explosion-Proof Double Girder Overhead Crane

  • The explosion-proof double girder overhead crane uses stainless steel or nylon lifting blocks to avoid flames caused by friction.
  • The ex proof crane and trolley wheel surfaces are made of stainless steel or beryllium bronze steel, materials less likely to produce sparks.
  • Equipped with soft start explosion-proof motors for smooth operation, reducing impact and spark resistance.
  • Designed with good rigidity and strong explosion-proof capabilities.
  • All our explosion-proof double girder overhead cranes are manufactured in accordance with GB 3836.2-2010 and JB/T 5897-2014 standards, ensuring safety, reliability, extreme durability, low maintenance, and a long service life.
  • Features automatic cutoff of lifting movement at upper and lower positions.
  • Electronic overload protection.
  • High component interchangeability, facilitating easy replacements.
  • External parts of the explosion proof double girder overhead crane are made from non-sparking materials for explosion-proof safety.

Explosion-Proof Certificates

Our explosion-proof products have passed the IECEx for global standards, ATEX for Europe, CCC, Mining Safety Certificate, and Explosion-Proof Qualification Certificate for China.
