Explosion Proof Overhead Crane Overview
The term “explosion-proof” indicates equipment designed to prevent the ignition of flammable substances like gases, vapours, dust, or fibres. In industrial settings where these volatile materials are prevalent, the risk of explosions is a constant concern. Single girder explosion proof overhead cranes are engineered to operate in these hazardous environments without introducing the risk of ignition.
The explosion-proof Single Girder Overhead Crane mainly consists of a crane travelling mechanism, electrical system, bridge, Explosion Proof Electric Hoist, etc.

The explosion-proof single girder crane is a small overhead crane with light lifting capacity, installed with a flame-proof hoist, with all the motors and electrical equipment of the explosion-proof crane manufactured in line with international standards and regulations. The lifting capacity of the single girder explosion-proof crane is 1 to 20 tons and the working class is A3.
Advantages of Single Girder Explosion Proof Overhead Crane
- Reasonable design, strong explosion-proof ability
- Company structure, good rigidity
- Installed with adjusting speed converter, steady travelling
- High safety and reliability
Key Features of Single Girder Explosion Proof Crane
1. On mechanical system (Single girder explosion-proof overhead cranes boast a unique structural design that optimizes load-bearing capacity while minimizing exposure to potential ignition sources. The single girder design enhances the crane’s manoeuvrability and adaptability in various industrial settings.)
- High quality materials: Q235B or Q345B
- Superior steel plates welded rectangular tube legs
- Trinity-drive system or traditional drive by motor and reducer
- Smoothly moving, effectively braking, long service life
2. On electrical system (These cranes incorporate explosion-proof components, including motors, wiring, and electrical systems, that are carefully sealed to prevent the escape of sparks or heat. The use of non-sparking materials in critical areas further reduces the risk of ignition.)
- Independent and simultaneous control of all the electric hoist and crane movements.
- The electric hoist mobile power supply is constituted of flat cables, special cables, galvanized slippery course small cable pulley, etc.
- Smoothly moving, beautiful appearance
3. On safety measures (Single girder explosion-proof overhead cranes utilize advanced ignition prevention measures, such as temperature monitoring and spark-resistant features. These mechanisms actively identify and eliminate potential sources of ignition, contributing to the overall safety of crane operations.)
- Overloading protection
- Height limit switches
- Speed limit switches: fast to slow and stop
- Buffer devices to hoist trolley and crane bridge
- Lockable Mains Isolator at the end of the runway
- Warning indicator: anti-collusion device and flashing lights and warning sound.
- Motors with temperature control devices, with the insulation class F.
- Self-adjusting, twin, disc brake on hoist motion, asbestos-free brake
- Anti-Derailment Device on Crane and Crab Unit, Non-Sparking Type
- Crane, Crab Wheels and Crane Hook made from Anti-Sparking Material
Flame Proof Hoists: A Crucial Component in Single Girder Cranes
While the structural design of single girder explosion-proof overhead cranes is pivotal in preventing internal ignition, the hoist remains a critical component in lifting operations. Flame-proof hoists, designed to complement explosion-proof cranes, ensure that lifting activities are conducted without introducing sparks or heat.
- Enhanced Safety Measures: Flame-proof hoists share design considerations with explosion-proof cranes, incorporating non-sparking materials and effective sealing. The hoist’s motor and electrical components are enclosed to prevent the escape of sparks or heat, contributing to enhanced safety during lifting operations.
- Temperature Monitoring and Shutdown: To add an extra layer of safety, flame-proof hoists often integrate temperature monitoring systems. These systems automatically shut down the hoist if excessive heat is detected, preventing the risk of ignition and ensuring a proactive approach to safety.
Applications of Single Girder Explosion Proof Overhead Crane
- Manufacturing Industry: In manufacturing plants where the movement of heavy loads is routine, single girder explosion-proof overhead cranes provide a safe and efficient solution. The single girder design allows for increased flexibility in navigating tight spaces, making them ideal for assembly lines and production floors.
- Chemical Processing Plants: Chemical processing plants deal with a wide range of volatile substances. Single girder explosion-proof overhead cranes are designed to operate in these environments, facilitating the safe lifting and movement of materials without introducing the risk of ignition.
- Waste Management Facilities: Waste management facilities often handle combustible materials. Single girder explosion-proof overhead cranes are well-suited for such environments, where their structural design and explosion-proof features ensure the safe and efficient handling of waste materials.
Safety Standards and Certification of Explosion Proof Crane
- Certifications and Compliance: Single girder explosion-proof overhead cranes should adhere to industry-specific certifications and compliance standards. This includes certifications from organizations such as the Occupational Safety and Health Administration (OSHA) in the United States and the ATEX directive in Europe.
- Periodic Inspections: Regular inspections and adherence to maintenance schedules are essential to ensure the continued compliance of single girder explosion-proof overhead cranes. Periodic assessments help identify wear and tear, allowing for timely repairs and replacements to maintain optimal safety levels.
