Double Girder Overhead Cranes for Heavy Duty Applications

Double Girder Overhead Cranes are widely used for heavy-duty lifting in industrial environments where high capacity, long span, and continuous operation are required. If you are handling steel coils, large machinery, containers, or bulk materials, this type of crane gives you better stability and higher lifting efficiency than single girder systems. At Yuantai Crane, we design and manufacture Double Girder Overhead Cranes for global customers. Our cranes are used in steel plants, manufacturing workshops, power stations, warehouses, and ports. You can choose from different configurations such as LH, QD, QE, and QZ models depending on your application.

Types Of Double Girder Overhead Cranes

Double girder overhead cranes come in several configurations to match different working conditions and lifting needs. Choosing the right type depends on your load weight, lifting frequency, and the kind of materials you handle.

1. LH Double Girder Overhead Cranes

LH Double Girder Overhead Cranes use an electric hoist as the lifting mechanism, which makes the overall design simple and easy to maintain. They are well suited for medium-duty work where lifting tasks are frequent but not extremely heavy. If your daily operation involves machinery assembly, warehouse material handling, mold positioning, or general workshop maintenance, this type offers a practical solution. You will also benefit from its lower initial cost and energy efficiency compared to winch trolley cranes, while still getting stable performance and smooth lifting.

• Lifting Capacity:5-65t
• Lifting Height:6-22 m
• Span:10.5-31.5 m
• Working Temperature:-20-+40 ℃
• Working Duty:A3–A5

2. QD Double Girder Overhead Cranes

QD Double Girder Overhead Cranes are equipped with a winch trolley, which gives them strong lifting power and durability for demanding environments. This type is designed for heavy-duty applications where large loads must be handled safely and continuously. You will often see these cranes in steel mills, casting plants, and heavy manufacturing workshops because they can operate under high temperatures and tough working conditions. If your project requires lifting from 5 tons up to 500 tons or more, a QD crane provides the strength, stability, and long service life needed for such tasks.

• Lifting Capacity:1-500 ton
• Lifting Height:1-50 m
• Span:7.5-31.5 m
• Working Temperature:-20-+40 ℃
• Working Duty:A3–A7

3. QE Double Girder Overhead Cranes with Two Trolleys

QE Double Girder Overhead Cranes feature two trolleys mounted on the same bridge, which gives you more flexibility when lifting complex loads. You can operate the trolleys together for synchronized lifting or independently depending on your needs. This design is especially useful when handling long or oversized materials such as steel beams, pipes, or large structural components. It also allows you to rotate or precisely position loads, which improves safety and control when dealing with uneven weight distribution.

• Lifting Capacity:2.5+2.5-200+200 ton
• Lifting Height:customized
• Span:10.5-31.5m
• Working Temperature:-20-+40 ℃
• Working Duty:A5，A6

4. QZ Double Girder Grab Overhead Cranes

QZ Double Girder Overhead Cranes are fitted with a grab bucket instead of a hook, making them ideal for bulk material handling. They are commonly used for materials like coal, sand, scrap metal, and grain, where manual handling is not practical. You will typically find these cranes in ports, power plants, and waste processing facilities, where efficiency and speed are important. If your operation involves loading, unloading, or sorting loose materials, this type of crane can significantly improve productivity while reducing labor costs.

• Lifting Capacity:5-120 ton
• Lifting Height:1-50m
• Span:10.5-34.5 m
• Working Temperature:-20-+40 ℃
• Working Duty:A5–A7

5. Double Girder Electromagnetic Overhead Crane

A double girder electromagnetic overhead crane is specially designed for handling magnetic materials such as steel plates, billets, scrap metal, and coils. It uses an electromagnetic lifting device, which allows you to quickly pick up and release loads with high precision. This type of crane is very popular in steel mills, metal processing plants, and warehouses where ferrous materials are handled frequently. You can control the magnet through the operator cabin or remote system, making the operation simple and efficient. The crane usually includes a backup power system to prevent the load from dropping during a power failure, which improves safety and reliability.

• Lifting Capacity:5t-500t
• Lifting Height:3m-30m
• Span:10-32m
• Working Temperature:-20-+40 ℃
• Working Duty:A5–A7

6. QB Double Girder Explosion-Proof Overhead Crane

The QB double girder explosion-proof overhead crane is built for hazardous environments where flammable gases, vapors, or dust may be present. It is commonly used in industries such as petrochemical plants, chemical factories, and oil and gas facilities. All electrical components, motors, and control systems are designed to meet strict explosion-proof standards, reducing the risk of sparks or ignition during operation. This crane provides stable lifting performance while ensuring a high level of safety for both operators and equipment. When you work in environments with explosion risks, choosing this type of crane helps you comply with safety regulations and protects your facility. Its durable structure and reliable design also make it suitable for continuous and demanding industrial use.

• Lifting Capacity:5-100 ton
• Lifting Height:1-50 m
• Span:10.5-31.5m
• Working Temperature:-20-+40 ℃
• Working Duty:A5–A7
