Overview
Mainly consists of bridge structure, lifting mechanism, crane traveling mechanism, electric equipment etc. Explosion-proof performance of all motors and electrical equipments of explosion-proof overhead cranes is in line with GB3836.2-2000 "for explosive gas atmospheres with explosion-proof electrical equipment-Part 2: Flameproof "d", and the whole performance is in line with provisions of the standards of explosion-proof bridge cranes JB/T5897-1991.
The proof marks are Exd Ⅱ BT4 and Exd Ⅱ CT4. Applied to sites where explosion transfer capacity is not higher than the II B or II C-class, and the sites with explosive air mixture formed with inflammable gas (or steam) and air whose factory ignition temperature groups of not less than the T4 group.

Certifications
Explosion-proof overhead cranes are designed for hazardous environments where flammable gas, vapor, or dust may be present, such as chemical plants, oil and gas facilities, paint workshops, and grain processing plants. These cranes include single-girder explosion-proof overhead cranes and double-girder explosion-proof overhead cranes, each built to meet strict safety standards like ATEX or IECEx. If you need a solution for light to medium-duty lifting, the single-girder design is a practical choice. It has a simpler structure, lower cost, and is easier to install while still providing reliable explosion protection. For heavier loads, higher duty cycles, or more demanding operations, the double-girder design offers stronger stability, higher lifting height, and better performance under continuous use. Both types use explosion-proof motors, electrical components, and control systems that prevent sparks and reduce ignition risk.
Single Girder Explosion-Proof Overhead Crane
The LB single girder explosion-proof overhead crane is designed for environments where flammable gases, vapors, or dust may be present, such as chemical plants, oil facilities, and paint workshops. It uses an explosion-proof electric hoist and specially protected electrical components to prevent sparks during operation. The single girder structure keeps the crane lightweight and cost-effective, while still providing reliable lifting performance for light to medium-duty tasks. Key components such as motors, control panels, and limit switches are built to meet explosion-proof standards, and the crane usually complies with ATEX or similar safety requirements. If you work in a hazardous environment and need a safe and efficient lifting solution, this crane helps you handle materials with confidence while protecting both your facility and your team.

Double Girder Explosion-Proof Overhead Crane
The double girder explosion-proof overhead crane is built for heavier loads and more demanding working conditions in hazardous areas. It uses a strong double girder structure that provides higher lifting capacity, better stability, and greater lifting height compared to single girder designs. This type of crane is ideal for industries such as petrochemical plants, gas processing facilities, and heavy chemical production lines where both safety and performance are critical. Like the LB type, it uses explosion-proof motors, electrical systems, and controls, all designed to eliminate ignition risks. The trolley runs on top of the girders, which allows for more space and smoother load handling. If your application involves heavy-duty lifting in explosive environments, this crane gives you the strength, safety, and reliability needed for continuous operation.
