An explosion-proof overhead crane is a specialized lifting equipment used in flammable and explosive hazardous environments. It ensures operational safety through special explosion-proof design. The details are as follows:

Main Characteristics:

All electrical components, including the motor, electrical cabinet, and control switches, adopt a flameproof enclosure (type 'd') design. This design completely seals elements that may produce electric sparks within a sturdy housing. Even if an internal explosion occurs, it prevents flames from spreading to the external hazardous environment.

Some models use technologies like spark-resistant wheels to reduce the risk of sparks from friction.

Besides being suitable for explosive gas atmospheres (e.g., Groups IIA, IIB, IIC, Temperature Class T4), there are also models specifically designed for combustible dust environments (e.g., DIP rating).

It is suitable for Zone 1 and Zone 2 in hazardous area classification. Its use is strictly prohibited in Zone 0, where explosive mixtures are present continuously or for long periods.

The structure is compact and lightweight.

The common rated lifting capacity is 1 to 20 tons, with a maximum可达 30 tons. The span is typically between 7.5 meters and 28.5 meters.

The duty class is generally A3-A5, which is light to medium. It is suitable for places with medium or low frequency of use and is not suitable for high-intensity, heavy-duty workshops.

It offers two operation modes: floor control (via pendant) and remote control. Remote control enables operation from a distance, further enhancing the safety of personnel in hazardous areas.

Primary Application Scenarios:

This equipment is specifically designed for industrial environments where flammable, explosive gases, vapors, or dusts exist. Its main applications include:

Petroleum, Chemical, and Pharmaceutical Industries: Used in refineries, chemical plants, and pharmaceutical workshops for lifting material drums, reactors, packaging items, etc.

Oil & Gas and Military Industries: Used in high-risk locations such as oil and gas storage stations, oil field operation areas, and military production facilities.

Metallurgy and Power Generation: Used for equipment maintenance and material handling in areas with explosive dust or gases, such as coal bunkers in steel plants or hydrogen production stations in power plants.

Warehousing and Processing: Used in warehouses storing flammable and explosive chemicals, grain processing plants (dust environments), paint spray booths, etc.

Important Notes:

The product must be selected based on the specific type of hazardous medium (gas or dust, specific substance) and zone classification in the operational environment to match the corresponding explosion-proof rating and temperature class.

Due to its duty class limitations, it is not suitable for high-frequency handling operations.
