What are the Different Types of Crane Girders?

When it comes to material handling and lifting solutions in industrial settings, cranes play a crucial role. One of the essential components in a crane system is the crane girder, a horizontal beam that supports the load and allows the crane to move it along its span. Understanding the different types of crane girders is important for selecting the right equipment for your specific applications. In this article, we’ll explore the most common types of crane girders, how they work, and where they’re used.

1. Single Girder Cranes

The Grúa monorraíl is one of the most widely used types of cranes in industries. As the name suggests, it features a single beam or girder that supports the hoist and trolley. This type of crane is ideal for light to medium-duty lifting tasks and offers advantages like:

• Lower cost compared to double girder systems
• Compact design, requiring less space
• Easier and faster installation
• Suitable for workshops, warehouses, and manufacturing plants

Single girder cranes are commonly available in overhead and gantry configurations, depending on the environment and lifting needs.

2. Single Girder Overhead Cranes

A popular category of single girder cranes is the Single Girder Overhead Crane. This system features a girder mounted on end trucks that run on fixed overhead runways. The hoist travels along the girder, making it a versatile and efficient choice for indoor material handling.

These cranes are widely used in:

• Factories
• Assembly lines
• Repair shops
• Warehouses

Their simple design and economic value make them a go-to solution for lifting needs up to 20 tons.

3. Grúas semipórtico

A Grúa semipórtico combines the benefits of an overhead crane and a gantry crane. It features one side mounted on a runway beam and the other side supported by a floor-mounted rail. This hybrid design offers greater flexibility and is ideal for areas where one side of the workspace cannot support a full overhead runway system.

Key advantages include:

• Cost-effective use of existing structures
• Space-saving design
• Ideal for outdoor and indoor applications
• Flexible lifting solutions for workshops, construction sites, and yards

Semi gantry cranes are perfect for lifting medium to heavy loads in environments where installation of a full gantry crane isn’t feasible.

Which Crane Girder is Right for You?

Choosing the right type of crane girder depends on several factors:

• Load capacity: Determine the maximum weight you need to lift.
• Span length: Measure the distance the crane must cover.
• Working environment: Consider whether the crane will be used indoors or outdoors.
• Budget and space limitations: Evaluate your infrastructure and financial resources.

By understanding these factors and the different crane girder types available, you can select the most suitable option for your material handling needs.

Conclusion

Crane girders are fundamental components that determine the crane’s load-bearing capacity, operational efficiency, and overall safety. Whether you choose a grúa monorraíl, a semi gantry crane, or a single girder overhead crane, it’s essential to work with a reliable manufacturer that provides customized, high-quality solutions.
