PRODUCTS & CASES

QB Type Explosion Proof Overhead Crane is a specialized lifting solution designed for hazardous industrial environments where flammable gases, vapors, dust, or explosive materials may exist. It is engineered to provide safe and reliable material handling in areas with strict explosion protection requirements.

All critical electrical and mechanical components, including motors, control systems, and lifting mechanisms, are manufactured according to international explosion-proof standards. The crane is equipped with an explosion-proof electric hoist featuring explosion-resistant motors and protective enclosures, effectively preventing ignition sources caused by electrical sparks, overheating, or mechanical failures.

With a typical lifting capacity range of 5–100 tons, the explosion-proof bridge crane can meet different heavy lifting requirements in chemical plants, petroleum facilities, energy industries, and other hazardous working environments.

QB explosion-proof overhead cranes are widely applied in areas containing combustible gases such as hydrogen, acetylene, ethylene, and propane, as well as industries involving oil, natural gas, chemicals, pharmaceuticals, and other high-risk materials.

Explosion-proof overhead cranes are specifically developed for safe lifting operations in explosive, flammable, and dust-sensitive environments.

Chemical and Petrochemical Industry

Used in oil refining, gas processing, chemical production, pesticide manufacturing, and fertilizer plants for handling raw materials, equipment, and finished products.

Military Industry

Applied in production facilities and storage areas involving ammunition, explosives, and other hazardous materials where strict safety requirements are required.

Pharmaceutical and Food Processing Industry

Suitable for alcohol extraction workshops, powder production areas, and facilities handling flammable materials or sensitive products.

Steel and Metallurgical Industry

Used for lifting and transporting raw materials, semi-finished products, and production equipment in steel manufacturing environments.

Coal Mines and Underground Facilities

Designed for operation in areas with high concentrations of methane or combustible dust, providing safe material transportation solutions.

Hazardous Goods Warehouses and Logistics Centers

Used for loading, unloading, and transferring flammable or explosive materials in specialized storage facilities.

Advanced Explosion-Proof Design

All major components are specially designed for hazardous environments, including:

• Explosion-proof motors

• Explosion-proof electric hoists

• Protected electrical control systems

• Flame-resistant components

This design significantly reduces the risk of ignition and ensures safe operation.

Flexible Lifting Configurations

The crane can be equipped with different lifting attachments according to application requirements, including:

• Hook systems

• Electromagnetic lifting devices

• C-hooks

• Customized lifting tools

This allows the crane to handle different types of industrial materials.

Strong and Reliable Structure

The main girder and end beams are manufactured from high-quality welded steel structures, providing excellent strength and durability.

Non-metallic components use anti-static materials to prevent electrostatic accumulation and improve safety in explosive environments.

Certified Explosion Protection

The crane complies with international explosion-proof safety requirements and can meet certifications such as:

Ex d IIC T4

The explosion-proof design ensures reliable operation in hazardous areas with strict safety regulations.

Easy Installation and Maintenance

The explosion-proof motor and electrical components adopt modular designs, allowing easier installation, inspection, and replacement.

This reduces maintenance time and minimizes production downtime.

Comprehensive Safety Protection

The crane is equipped with multiple safety systems, including:

• Overload limiters

• Travel limit switches

• Emergency stop devices

• Safety monitoring systems

When overload conditions occur, the system can automatically stop operation to protect equipment and operators.

Flexible Control Methods

QB explosion-proof overhead cranes support different operating methods:

• Ground pendant control

• Wireless remote control

• Operator cabin control

These options improve operational flexibility and reduce safety risks caused by blind areas.
