General purpose overhead crane
ATEX Certified Flameproof Bridge Crane for Hazardous Gas & Vapor Environments
1. Product Overview
The Weiyuan Explosion-Proof Overhead Bridge Crane is purpose-built to deliver safe material handling across hazardous locations where combustible vapors, gases, or volatile dusts are present. Certified to international ATEX and IECEx standards for Zone 1, Zone 2, Zone 21, and Zone 22, this crane incorporates explosion-proof motors, flameproof electrical control panels, and non-sparking mechanical hardware to eliminate ignition risks.
2. Key Advantages & Technical Highlights
- Certified Flameproof Enclosures: Ex d IIB T4 / Ex d IIC T4 Gb rated enclosures isolate all electrical switches, contactors, and motor brushes from ambient gases.
- Non-Sparking Mechanical Components: Features bronze-coated hook blocks, brass travel wheels, and stainless-steel wire rope guide assemblies.
- Anti-Static Structural Grounding: Comprehensive equipotential bonding and anti-static wire ropes prevent dangerous static electricity accumulation.
- Dual Mechanical Braking System: Explosion-proof disc brakes engage instantaneously upon loss of power, securing the load in volatile settings.
