Types of Explosion-Proof Bridge Cranes

Explosion-proof overhead cranes are available in single and double girder configurations and are designed for safe material handling in hazardous environments.

Explosion-proof bridge cranes are specially designed to handle hazardous environments where there is a risk of explosion due to the presence of flammable gases, dust, or vapors. These cranes are built with specific safety features to prevent ignition and ensure safe operation in these environments. There are different types of explosion-proof bridge cranes based on various applications and the level of protection required.

1. 5-20 ton Explosion-Proof Single Girder Overhead Cranes

Single girder explosion-proof cranes are a cost-effective safety solution with spans of up to 28.5 meters and lifting heights of up to 50 meters, making them widely applicable in hazardous environments. It has the following main characteristics:

• Suitable for Lighter to Medium Loads: Explosion-proof single girder cranes are typically designed for lighter to medium lifting capacities, adequate for handling equipment components, materials, and tools within various plant sections. Moderate capacity explosion proof cranes are sufficient for many maintenance and light production tasks.
• Cost-Effective Solution: Explosion-proof single girder cranes are generally less expensive than double girder models, making them a budget-conscious choice for areas where heavy lifting is not the primary requirement. If you are on a budget and the lifting capacity meets your needs, this will fit the bill perfectly.
• Adaptable to Various Spans and Headroom: Explosion-proof single girder cranes can be customized with varying spans and headroom configurations to fit different building dimensions and workspace layouts within petrochemical plants. For some of the parameters, you can view the charts below or contact us to talk.

2. Explosion-Proof Double Girder Overhead Cranes

Explosion-proof double girder overhead cranes are engineered for heavy-duty lifting and demanding applications within petrochemical plants, where exceptionally heavy loads need to be handled safely in hazardous areas. Double girder explosion-proof overhead cranes have the following characteristics:

• heavy-duty Lifting Capacities: Explosion-proof double girder cranes are intended for heavy applications, capable of handling enormous equipment components, reactors, pressure vessels, and other heavy loads encountered in petrochemical processing and maintenance. High capacity explosion-proof cranes are required for heavy component handling in petrochemical operations.
• Long Span Capabilities for Large Areas: Explosion-proof double girder cranes can be engineered with long spans to cover expansive processing areas, storage facilities, or maintenance bays within petrochemical plants, providing comprehensive lifting coverage for large-scale operations.
• Robust and Durable Construction: Explosion-proof double girder cranes feature extremely robust and heavy-duty construction, built to withstand continuous operation, demanding duty cycles, and the harsh conditions often found in petrochemical environments.

3. Explosion-Proof Under-Running Overhead Cranes

Explosion-proof under-running overhead cranes, also known as explosion-proof underhung cranes or low headroom explosion-proof cranes, are specifically designed for facilities with limited headroom where maximizing lifting height is crucial, even in hazardous locations. For areas with limited headroom, we have designed explosion-proof lifting solutions for space-constrained areas.

• Maximized Lifting Height in Low Headroom Areas: Explosion-proof under-running cranes, with their underhung trolley and hoist configuration, minimize the vertical space occupied by the crane, maximizing the usable hook height within buildings with low ceilings or overhead obstructions.
• Compact and Space-Saving Design: Explosion-proof under-running cranes offer a compact and space-saving design, well-suited for congested petrochemical plant areas where minimizing crane dimensions is important. Space saving explosion proof cranes are ideal for confined hazardous areas.

Conclusion

Explosion-proof bridge cranes are specialized lifting equipment designed for hazardous environments, particularly in petrochemical plants, where the risk of explosion due to flammable gases, vapors, or dust is high. There are various types of explosion-proof bridge cranes designed for different lifting needs. Whether it's light loads, heavy loads or space-constrained applications, Yuantai has the right solution for you.
