Explosion-proof overhead cranes are light-duty overhead lifting devices, mainly composed of explosion-proof electric hoists, motors, and electrical components. Our factory manufactures these cranes strictly in accordance with international standards and regulations to ensure safe and reliable operation in flammable and explosive environments.
Dafang Group’s explosion-proof crane products cover gas (Zone 1, Zone 2) and dust (Zone 21, Zone 22) hazardous areas. Gas explosion-proof models are suitable for Class A, B, and C gases and can operate in T4 temperature zones with a protection rating up to IP66. Dust explosion-proof models are suitable for various combustible dust areas and meet T4 requirements as well.
All products are manufactured in strict compliance with European standards such as ATEX100a (94/09/CE) and relevant CE directives, while also meeting applicable Chinese explosion-proof standards. We offer customized explosion-proof solutions for gas Zones 1 and 2, and dust Zones 21 and 22, based on customer requirements.
The product range includes explosion-proof jib cranes, single girder cranes, and double girder cranes, to meet varying load requirements and diverse operational scenarios.
The explosion-proof overhead crane is specially designed for flammable and explosive environments. It is widely used in industries such as petrochemical, coal mining, pharmaceuticals, grain processing, energy, power generation, military, and warehousing. It is suitable for hazardous zones classified as Zone 1/2 (gas) and Zone 21/22 (dust), compliant with T1–T4 temperature classes, and offers protection up to IP66.
