Explosion-Proof Single Girder Crane (1–20t) | ATEX/IECEx

The explosion-proof single girder crane is a critical overhead lifting system for facilities handling flammable materials, combining the space-saving economics of a single beam with the safety of explosion-proof components. This crane is specifically designed for Zone 2 and potentially Zone 1 hazardous environments where flammable gases, vapors, or combustible dusts are present intermittently or continuously. Its primary structure consists of a single main bridge beam, running along elevated runways, coupled with an explosion-proof electric hoist as the lifting mechanism. In a chemical plant, where mixing volatile solvents creates a constant risk, this crane operates safely to move 5-ton reactors or blend ingredients. Similarly, in a paint factory, it can transfer barrels of flammable resins without the risk of an arc or spark igniting the airborne vapors. The entire system, from the motor to the pendant controls, is enclosed in flameproof casings designed to contain any internal explosion. The control circuits are often intrinsically safe (Ex ia/ib), limiting electrical and thermal energy to levels below what is required to ignite a specific hazardous atmospheric mixture. For facilities looking to maximize vertical space utilization while adhering to strict safety standards, the explosion-proof single girder crane offers a cost-effective solution.
