Explosion-proof Double Girder Overhead Crane

• The explosion-proof double-girder bridge crane adopts HB (BCD) and HBS (BMD) explosion-proof electric hoists as the lifting mechanism.
• The crane is suitable for capacities ranging from 1 to 10 tons, spans of 7.5 to 22.5 meters, and operating temperatures between -25℃ and +40℃.
• Specifically designed for flammable and explosive environments, it features a compact structure, stable operation, and high explosion-proof rating. It is widely used in petrochemical, coal mining, military, and other hazardous industries.
• Equipped with explosion-proof electric hoists, it ensures safe material handling and equipment maintenance in high-risk areas.
• The crane has a robust structure, excellent durability, and comprehensive safety protections to ensure long-term stable operation.
• The working duty level of A3 ensures suitability for light to moderate usage, ideal for industries requiring safe material handling with moderate operational frequency.

• Manufactured according to international standards with variable frequency drive (VFD) control for smooth and efficient operation.
• All steel structure plates are shot blasted, achieving a surface cleanliness of Sa2 grade for superior corrosion resistance.
• Coated with two layers of epoxy zinc-rich paint for excellent appearance and durability.
• Welding is performed using gas shielded welding or submerged arc welding, with ultrasonic testing (UT) for weld integrity.
• All explosion-proof electric hoists undergo load testing before shipment, with dynamic load at 1.1 times and static load at 1.25 times rated capacity.
• Equipped with standard safety monitoring systems, including audible and visual alarms and infrared anti-collision devices to ensure equipment and personnel safety.
• Wind speed meters are installed for lifting heights above 15 meters; flexible supports are provided for spans exceeding 35 meters to enhance structural stability.
• Features electronic correction for improved operational accuracy.
• Power supply options include cable or busbar systems, adaptable to different site requirements
