Motor and electrical appliances of this crane are explosion proof type. When explosion proof grade is ExdII CT4, travelling mechanism should do spark proof treatment. The whole machine meets standards of JB/T10219-2001 (Specification for explosion-proof cranes with electric wire rope hoist),explosion proof grade have ExdII BT4 and ExdII CT4 two kinds. It has characteristic of rational construction, perfect appeaance and strong Ex technical performace.

This product is suitable for areas where the explosion-transmission is not higher than IIB or IIC and the ignition temperature group of inflammable gas or explosive mixture of steam and gas is not lower than T4. Applicable dangerous zones are zone 1 and zone 2. (please refer to GB 3836.1-2000 for details).

It is generally controlled on the ground, but control from the driver' cabin is also allowable. The working grade is intermediate.

(Note: 5-10t crane does not have an auxiliary hook.)

This crane adapts to the environment in factory that have explosive gas formed by inflammable gas, steam and air of which explosion proof grade is less than B grade or C grade and ignition 

group is more than T4 (135℃)group. And the explosion proof electric hoist adapts to 1 area or 2 area, not 0 area.

Our explosion-proof crane is specifically designed for use in industrial environments where the presence of potentially explosive gases or vapors is a concern. This includes factories and facilities 

where flammable gases, steam, and air can create hazardous conditions. 

1. Environment Compatibility:

The crane is suitable for environments classified with explosion-proof grades below B or C. This ensures that it can operate safely in areas where the risk of explosion is present, maintaining 

compliance with stringent safety regulations.

It is particularly designed for zones with ignition groups classified as T4, which can operate at temperatures up to 135°C. This allows for secure functioning in environments where the risk of 

ignition from heat is critical.

2. Applicable Areas:

This equipment is specifically tailored for use in Area 1 or Area 2 classified zones. These areas are defined by the frequency and duration of the presence of flammable gases or vapors, thus 

ensuring that the crane operates safely under conditions where such hazards may intermittently occur.

It is not certified for use in Area 0, where the constant presence of explosive atmospheres would render such equipment unsuitable.

3. Industrial Applications:

Suitable industrial applications include petrochemical plants, gas storage facilities, and wastewater treatment plants where explosive atmospheres may arise due to the presence of volatile 

substances. The crane can be utilized for various lifting operations in these environments, such as moving heavy equipment, handling raw materials, and transporting completed products within 

the facility.

4. Safety and Compliance:

The explosion-proof design adheres to international safety standards, providing peace of mind for operators and maintenance personnel in potentially perilous settings.

Regular safety inspections and compliance checks ensure that the crane maintains its effective functionality and safety standards over time.

In summary, this explosion-proof crane is engineered to meet the rigorous demands of hazardous industrial environments, ensuring both safety and efficiency in operations involving combustible 

gases and vapors.
