The Explosion-proof Multi-point Electric Single-girder Suspended Crane is a specialized overhead lifting solution manufactured by Henan Mine (Model: LXB). This crane is specifically engineered for hazardous environments where flammable gases, vapors, or combustible dusts may be present, while also addressing the challenge of multi-point lifting operations across extended work areas.

Unlike standard single-girder cranes that run on overhead rails fixed to building structures, the suspended (underslung) configuration features the crane running on the bottom flange of the runway beams that are suspended from the roof structure. This unique design provides complete floor-to-ceiling coverage and allows the crane to transfer between multiple bays or workstations without gaps, making it ideal for facilities requiring material movement across wide or irregularly shaped areas.

The explosion-proof multi-point electric suspended crane is a special-purpose crane. It is specially designed and produced to meet the needs of large-span industrial plants or warehouses, such as aircraft manufacturing plants and aircraft maintenance workshops. It is a multi-point (multi-track) suspended crane.

This explosion-proof multi-point suspension electric single girder crane is widely used in underground tunnels, workshops and yards of coal mines and metal mines, as well as other working sites with flammable and explosive gas and dust.

The crane combines three critical features:
1.Explosion-proof construction – Meets ExdⅡBT4 / ExdⅡCT4 standards for safe operation in hazardous zones (Zone 1, 2 for gas; Zone 21, 22 for dust)
2.Multi-point operation – Multiple hoists or control points can work independently or synchronously across the same runway system
3.Suspended configuration – Underslung design maximizes floor space utilization and enables inter-bay transfer

Core Applications:
1.Chemical processing plants: Handling raw materials, intermediates, and finished products in explosive atmospheres
2.Petrochemical refineries: Loading/unloading equipment, maintenance lifting, and material transfer in hazardous areas
3.Pharmaceutical manufacturing: Production areas with alcohol or solvent vapors requiring explosion-proof equipment
4.Paint and coating facilities: Paint mixing rooms, spray booths, and storage areas with flammable vapors
5.Coal processing plants: Handling coal dust in classified hazardous areas (Class I)
6.Food processing: Grain handling facilities with combustible dust hazards
7.Aerospace and defense: Fuel handling areas and ordnance facilities
