PRODUCT INTRODUCTION

The Explosion-Proof Single Girder Overhead Crane is a specialised lifting solution engineered for safe operation in hazardous environments where flammable gases, vapours, dusts, or fibres are present. Every component—from hoist motor to electrical enclosure—is designed, manufactured, and certified to prevent the equipment from becoming an ignition source during operation. This crane is not a standard overhead crane with added guards; it is a purpose-built machine whose entire electrical and mechanical system is configured to comply with explosion-proof standards for designated hazardous zones, ensuring protection of both personnel and assets when standard industrial cranes cannot be used.

FEATURES

Full Explosion-Proof Protection Across All Components — The hoist motor, travel motors, brakes, electrical enclosures, limit switches, push-button pendant, and control panel are all individually certified as explosion-proof. This is a fundamental safety prerequisite for hazardous area operations.

Flameproof Enclosure Design (Ex d) — Motors and critical electrical components are enclosed in flameproof housings that can withstand an internal explosion without transmitting flame to the surrounding atmosphere.

Spark-Free Operation — Brakes use non-sparking materials and special friction pairs. Hooks, wheels, and trolleys are made of copper alloy or stainless steel to eliminate the risk of mechanical sparks during contact. Copper-plated or copper-alloy contact surfaces are standard at critical points.

Temperature Monitoring & Protection — Continuous temperature monitoring of critical motor components ensures automatic shutdown before surface temperatures exceed the ignition temperature of the surrounding gas or dust.

Standardised Safety Protection — An overload limiter and emergency stop button form the primary protection layer. Upper and lower limit switches ensure safe hoist travel, and a phase failure protection device verifies correct power sequence before motor operation.

Optional Advanced Safety Features — An emergency shutdown system enables power isolation in critical situations. Anti-collision sensors for areas where multiple cranes operate together are available as an option. Lightning and surge protection can be added for outdoor or exposed installations.
