Product Introduction

Explosion-Proof Overhead Crane is designed for safe material handling in explosive environments. It incorporates specialized explosion-proof electrical components and spark-proof structural designs to prevent electrical sparks, mechanical friction, and excessive surface temperatures from triggering explosions.

Main Types

Explosion-Proof Hoist Overhead Crane

Explosion-Proof Electric Single-Girder Crane (e.g., LB type explosion-proof electric single-girder crane)

Explosion-Proof Electric Double-Girder Crane

Core Features

Rigorous Explosion-Proof Control: Engineered to eliminate three critical hazards:

High Surface Temperature

Controls heat generated by mechanical friction or electrical overloading to stay well below the ignition temperature of explosive gas mixtures.

Sparks & Arcing

Prevents electrical sparks from component switching/short circuits, as well as mechanical sparks caused by friction or collision.

Static Discharge

Eliminates static electricity risks accumulated on plastic enclosures or conductive dust layers that could reach minimum ignition energy levels.

Applications

Widely used in hazardous, flammable, and explosive industries such as mining, oil & gas, chemical processing, and military manufacturing to ensure safe operations.
