A Russian machinery manufacturing plant needed a crane for handling large machine components and assemblies with high precision. The project required a reliable crane with a capacity of 64 tons (32+32 tons), a span of 22.5 meters, and a lifting height of 11 meters. After evaluating various solutions, the customer selected the AQ-NLH double girder overhead crane.
Why this type?
Customer Review – Mr. Ivanov, Plant Director:
“The AQ-NLH 64 ton girder overhead crane has been a great addition to our workshop. It combines strength with precision, and the dual 32-ton hoists allow us to handle large machinery components safely and efficiently. The performance has exceeded our expectations.”
A metal fabrication company in Kazakhstan needed a reliable girder bridge crane to handle steel coils and metal sheets inside their warehouse. The project required a balance of high precision, safety, and energy efficiency. After evaluating options, the customer chose the AQ-QDX double girder crane with a 10-ton capacity.
Why this type?
Customer Review – Mr. Beketov, Operations Manager:
“The AQ-QDX 10-ton crane has greatly improved our warehouse operations. It is precise, energy-efficient, and very stable when lifting steel coils. We are pleased with both the product quality and the installation service provided.”

The design of an overhead crane girder can be classified by structural form or by girder design.
| Type | Features | Capacity Range | Typical Applications |
|---|---|---|---|
| Single Girder Overhead Crane | One bridge crane girder supports trolley and hoist; compact, economical, easy to install | 5-25 tons | Workshops, warehouses, assembly lines |
| Double Girder Overhead Crane | Two crane bridge girders provide higher stability; trolley runs on rails on top of girders | 10-500+ tons | Steel plants, shipyards, heavy manufacturing |
| Type | Features | Advantages | Common Use |
|---|---|---|---|
| Ovrhead I Beam Crane | Uses rolled I-beam as the crane girder | Simple, cost-effective, ideal for short spans | Light-duty single girder cranes |
| Box Girder Crane | Fabricated box-shaped girder with excellent torsional rigidity and bending resistance | Strong, stable, suitable for long spans and heavy loads | Heavy-duty double girder cranes |
The overhead crane girder design is the core element that determines the strength, efficiency, and safety of any crane system. Whether you require a single girder I beam overhead crane for light lifting, or a double girder box girder overhead crane for heavy-duty, long-span applications, Aicrane has the right solution for you.
But with so many options available, a key question arises: how do you choose the right girder overhead crane for your specific application? Read on to find out.
Selecting the right bridge girder crane is crucial to ensure safe, efficient, and cost-effective lifting operations. With so many options – single girder, double girder, I-beam, box girder, or customized overhead beam cranes – understanding the key factors will help you make the right decision for your facility.
Primary Question: What is the maximum lifting weight required?
Considerations:
Primary Question: How wide is the area the crane must cover?
Considerations:
Primary Question: How often and intensively will the girder overhead crane operate?
Considerations:
Primary Question: Will the crane operate in a controlled or challenging environment?
Considerations:
Primary Question: Are there any unique lifting requirements?
Considerations:
Choosing the right girder overhead crane is not just about picking a model – it must be based on the specific requirements of your project: load capacity, span, operational frequency, environment, and any special lifting needs. Each factor directly influences whether a single or double girder crane, or an I-beam or box girder overhead crane, will provide optimal performance, safety, and cost-efficiency.

The bridge girder in crane, also known as the overhead crane beam, is the backbone of the crane, directly affecting its strength, stability, and operational performance.
Primary Load-Bearing ComponentThe girder in crane carries the entire load of the trolley, hoist, and lifted materials, ensuring it can safely handle its rated load without deformation. In single girder cranes, the load is concentrated on one beam. In double girder cranes, the load is shared between two beams.
Ensuring Structural Rigidity and StabilityThe overhead crane bridge girder maintains the horizontal and vertical stability of the crane during operation, reducing sway and deflection. It also provides a solid platform for the trolley and hoist to move smoothly, improving operational efficiency and reducing wear.
Supporting Crane ComponentsThe girder forms the foundation for all moving parts of the crane: trolley movement rails, hoist mounting points, electrical conduits and control systems. Proper girder design ensures these components function reliably and safely under load.
Proper girder overhead crane installation ensures structural integrity, precise alignment, and safe operation throughout the crane’s service life. This is a guide to assembling and installing bridge crane beams or girders.
A thorough pre-installation inspection reduces the risk of delays, misalignment, or damage during assembly.
Even slight misalignment can cause uneven load distribution, impacting the crane’s performance and safety.
Welding should follow industry standards, and bolted connections must be torqued precisely to maintain rigidity.
Proper alignment reduces wear on hoists and end trucks, ensures smooth trolley motion, and maximizes crane lifespan.
The assembly and installation of the bridge crane girder is a critical step to ensure the crane performs reliably and safely.
To support our customers, we offer professional installation services, including online guidance or on-site assembly, alignment, and commissioning, ensuring your girder eot crane is installed to high safety and performance standards.
I beam crane system is economical, lightweight, suitable for single girder light duty overhead cranes.
Overhead crane box girder design uses hollow welded structure with high torsional rigidity, ideal for double girder heavy duty bridge cranes.
