What Is a Double Girder Overhead Crane?

A double girder overhead crane is one of the most powerful and widely used lifting systems in modern industry. Designed for heavy-duty operations, it offers higher capacity, greater lifting height, and better stability compared to single girder cranes.

In this guide, you’ll learn what it is, how it works, and the main types used in China and global markets.

What Is a Double Girder Overhead Crane?

A double girder overhead crane consists of two parallel bridge girders mounted on runway beams. The hoist and trolley run on top of the girders, allowing for higher lifting height and increased load capacity.

Key Components:

• Double Girders (Beams): Provide strength and stability

• Hoist & Trolley: Mounted on top for efficient lifting

• End Trucks: Allow crane movement along rails

• Runway System: Supports the entire crane structure

Key Features & Advantages

1. High Load Capacity

• Typically ranges from 5 tons to 500+ tons

• Suitable for heavy industries like steel and shipbuilding

2. Higher Lifting Height

• Hoist runs on top of girders → maximizes hook height

3. Superior Stability

• Two beams distribute load evenly

• Ideal for precise and heavy lifting tasks

4. Customizable Design

• Span, height, and speed can be tailored

• Can integrate advanced control systems

Types of Double Girder Overhead Cranes

1. Hook Double Girder Overhead Crane

Overview:
The most common type, equipped with a hook for general lifting.

Applications:

• Machinery manufacturing

• Warehouses

• Steel plants

Widely used in both China and global markets due to versatility.

2. Grab Bucket Overhead Crane

Overview:
Uses a grab bucket instead of a hook to handle bulk materials.

Applications:

• Coal plants

• Cement factories

• Mining industries

Common in heavy industries worldwide.

3. Magnetic Overhead Crane

Overview:
Equipped with an electromagnetic lifter.

Applications:

• Scrap yards

• Steel processing plants

Especially popular in China’s steel recycling industry.

4. Ladle Crane (Foundry Crane)

Overview:
Designed for extreme heat and hazardous environments.

Features:

• Heat-resistant components

• High safety standards

• Redundant systems

Applications:

• Steel mills

• Metallurgical plants

Strong demand in both China and developed industrial countries.

5. European-Style Double Girder Crane

Overview:
Designed according to FEM/DIN standards, focusing on efficiency and compactness.

Features:

• Lightweight structure

• Energy-saving motors

• Variable frequency drive (VFD)

Trend:

Chinese manufacturers are increasingly adopting European designs for export markets.

Common Applications

Double girder overhead cranes are widely used in:

• Steel Industry: Handling molten metal and heavy steel

• Manufacturing: Assembly and equipment lifting

• Shipbuilding: Moving large structural components

• Warehousing: Heavy-duty material handling

• 5 Ton Overhead Crane for Warehouse
• 10 Ton Overhead Crane for Factory
• 15 Ton Double Girder Overhead Crane
• Gantry Crane Price

When Should You Choose a Double Girder Crane?

Choose this type if you need:

• Heavy lifting (20 tons and above)

• High lifting height

• Continuous and frequent operation

• High precision and safety

Final Thoughts

A double girder overhead crane is the best choice for heavy-duty industrial lifting. While it requires a higher initial investment, it delivers long-term efficiency, safety, and performance.

Simple Rule:

• Light-duty → Single Girder Crane

• Heavy-duty → Double Girder Crane

Pro Tip for Buyers

Before selecting a crane, always define:

• Load capacity

• Span and lifting height

• Working environment

• Duty cycle

 These factors determine the right configuration—not just the crane type.
