The Double Beam Explosion-Proof Bridge Crane is a special lifting equipment designed for hazardous environments containing flammable, explosive gas or dust. It is widely used in industries requiring strict safety protection and reliable explosion-proof performance.
Standards & Explosion-Proof Rating
All motors and electrical components comply with GB3836.2-2000 (Flameproof Enclosure “d”) standard for explosive gas atmospheres.
The overall crane design complies with JB/T5897-2006 “Explosion-proof Bridge Cranes”.
Explosion-proof ratings: Exd IIB T4 and Exd IIC T4.
Main Structure
Main Beam: Made of high-strength corrosion-resistant alloy steel or explosion-proof compliant materials. It effectively reduces risks caused by static electricity and sparks. Automatic submerged arc welding ensures high-quality welds and strong structural stability.
Electric Trolley: Uses I-beam track cable conduction system, ensuring safe and reliable power transmission while reducing operational hazards.
Electrical System: Equipped with explosion-proof motors, flameproof electrical components, and explosion-proof limit switches. The sealed structure effectively isolates internal sparks or arcs from external explosive environments.
Applications
Chemical Industry: Safe handling of flammable and explosive chemical materials.
Oil & Gas Industry: Suitable for environments with flammable gases and liquids.
Pharmaceutical Industry: Ensures contamination-free and safe production processes.
Coal Mining: Designed for dusty underground working environments requiring explosion protection.
Specification
Specifications can be customized according to user requirements such as lifting capacity, span, lifting height, and working environment.
