Explosion proof double girder overhead crane

Explosion Proof Overhead Crane

Explosion proof overhead crane is a crane used for special purpose. It has strong explosion proof performance, and it’s designed with reasonable structure. This kind of crane is adopted to occasions with explosive gas and dust. As one of the experienced overhead explosion-proof overhead crane manufacturers in China, Ellsen continues to provide quality explosion proof crane used in many industries, such as gas, oil, chemical, waste and sewage, power generation and waste handling.

As explosion-proof lifting equipment, explosion proof cranes are used in harsh and hazardous environment with flammable and explosive mixture, and they have good explosion proof performance and smooth operation, which ensures the safe and reliable work. The explosion-proof grades include EXdIIBT4 and EXdIICT4. To meet different environment requirements, the cranes are designed and manufactured with different configurations. If you need such a product, you can get the overhead explosion-proof crane quotation first and know better about the crane you would like to purchase.

Types of Explosion Proof Overhead Crane

According to girder quantity, the crane can be divided into electric single girder explosion proof overhead crane and double girder explosion proof crane. The double girder crane has greater lifting capacity than the single girder crane.

Single girder explosion proof crane is designed and produced to have explosion proof motor and electrics based on ordinary single girder crane, then it is manufactured with other mechanical explosion-proof measures, to make sure that the electric spark, heat and flammable dust caused by the crane and operating environment will not cause fire, explosion and other harmful effects. The wheel of the crane is stainless steel or Nylon wheel to avoid spark caused during the operations.

The motor and electrics of the double girder crane are explosion isolation type. When the explosion proof degree is ExdⅡCT4, the operating mechanism should adopt spark-proof treatment. When the crane is used indoors, work environment temperature should be -20℃–+40℃, air relative humidity should not be greater than 85% (when the ambient temperature is 25℃), and altitude should not exceed 1000m. When the environment conditions do not comply with the above conditions, the supplier should discuss and negotiate with the clients.
