What is the A55 Crane Rail?
The A55 Crane Rail is a specialized steel profile designed according to the DIN 536-1 standard, specifically tailored for heavy-duty industrial lifting and overhead crane systems. Characterized by its low-profile "A" type shape, it features a wide base and a robust head, which provides exceptional stability and pressure distribution under high wheel loads. This specific rail is widely utilized in port terminals, steel mills, and warehouses due to its high load-bearing capacity and durability in intense operating environments.
When evaluating the DIN 536 A55 rail , technical precision is paramount for ensuring compatibility with existing crane wheels. The DIN A55 rail dimensions feature a head width of 55mm, a base width of 150mm, and a height of 65mm, creating a low center of gravity that optimizes load distribution.

What are the advantages of the A55 Crane Rail?
The A55 crane rail (DIN 536) is a specialized, durable rail ideal for medium-duty crane systems, offering high stability, exceptional wear resistance, and precise alignment. Its robust design-150mm base, 65mm height, and 55mm head-reduces deformation and optimizes load distribution for industrial applications like ports, manufacturing, and warehousing.
Key advantages include:
- Robust Stability: The 150mm-wide base and 31mm-thick web provide superior structural support and bending resistance under moderate to heavy loads.
- High Wear Resistance: Generally made from 900A,U71Mn,50Mn steel with a high tensile strength of ≥ 645 MPa, it provides long-lasting service life.
- Precision Manufacturing: Compliant with DIN 536 P1:1991 standards, ensuring high dimensional accuracy and reduced friction for smoother crane wheel contact.
- Low Maintenance: The hard surface minimizes wear, reducing operational downtime and lowering maintenance costs.
- Versatile Installation: The rail is versatile for various setups and can be securely fastened to steel beams or concrete foundations.
Typical Applications of A55 Crane Rail
The primary applications of A55 crane rail span across multiple sectors where heavy lifting is a daily requirement.
- In maritime and port logistics, these rails are often installed on gantry cranes to handle shipping containers, where the A55 rail material must withstand corrosive salt-air environments.
- In the manufacturing sector, A55 overhead crane rail systems are utilized in automotive assembly lines and heavy machinery workshops to move large components safely across the factory floor.
- The mining and metallurgical industries also rely heavily on Burbach Rail A55 for transporting raw materials and finished products.
- In steel mills, where temperatures can be extreme and loads are massive, the durability of A55 steel rails ensures that production never halts due to track failure.
FAQ
1. What is the difference between A55 and other A-series rails like A65 or A75?
The primary difference lies in the head width and weight capacity. While the A55 rail has a 55mm head width, the A65 and A75 are wider and heavier, designed for even higher wheel loads. Choosing the A55 is often a balance between cost-effectiveness and meeting the specific load requirements of medium-to-heavy cranes.
2. Can A55 rails be used for standard train transportation?
No, A55 rails are specifically designed for crane applications and do not meet the geometric requirements for passenger or freight train wheels. Crane rails have a different profile (flatter and wider) compared to standard T-section railway tracks.
3. What are the most common steel grades available for DIN 536 A55 rails?
The most common grades of DIN 536 crane rail include S700, S900Q, and sometimes special wear-resistant alloys. S700 is typically used for standard applications, while S900Q offers higher tensile strength for extremely high-frequency operations.
4. How do I prevent rust on A55 rails during maritime shipping?
At GNEE RAIL, we apply a protective anti-rust coating to the A55 crane tracks and use moisture-proof bundling techniques. This ensures the rails arrive at your port without surface oxidation, even after long-distance sea transit.
5. Can I weld A55 rails together for a continuous track?
Yes, A55 rails are highly suitable for alumothermic welding. This process creates a smooth joint that eliminates the "click-clack" sound of wheels passing over gaps, reducing mechanical wear on the crane components and providing a smoother operation.
