What is the weight per meter for the A75 Rail?
The standard a75 rail weight per meter is approximately 56.2 kg/m. This weight is a critical specification within the European DIN 536 standard, as it reflects the substantial steel density required to support the massive wheel loads of overhead cranes and gantry cranes. By providing a weight of 56.2 kg for every meter of track, the DIN536 A75 Rail Weight ensures the structural mass necessary to absorb high-impact forces in demanding environments such as shipyards, steel mills, and heavy assembly workshops.
the weight advantages of the Profile A75 rail
- Optimal Load-to-Weight Ratio: With a weight of 56.2 kg/m, the A75 provides excellent load-bearing capacity for cranes handling 50–100 tons, often serving as a more cost-effective alternative to heavier rails like the A100 (74.3 kg/m).
- Wide Base Stability: The rail features a wide 200 mm base, providing superior lateral stability and reducing stress concentration compared to lighter rails, ensuring stability for heavy gantry and bridge cranes.
- High Strength-to-Weight Efficiency: The A75 has a thick web (45 mm) and a relatively low height (85 mm), creating a robust, low-center-of-gravity profile that resists deformation, which is crucial for handling high lateral forces.
- Improved Wear Resistance: When manufactured from high-strength steel (U71Mn), the A75 provides high hardness (≥ 260 HB), which can reduce wear by approximately 50% compared to conventional rails, extending its life to over 15 years.
- Easy Installation: Its standardized, lower profile allows for easier handling and installation compared to deeper or heavier crane rails, minimizing maintenance demands.

How does the weight of DIN 536 Standard A75 crane rail affect its performance?
The DIN 536 Standard A75 crane rail features a weight of 56.2kg/m, which directly determines its performance by providing a robust balance between structural stability, load-bearing capacity, and wear resistance in heavy-duty applications. Its design is engineered for high lateral strength and low center of gravity, which enhances stability under dynamic loads.
High Load-Bearing Capacity & Stability
- Massive Profile: With a base width of 200 mm and a height of 85 mm, the 56.2 kg/m profile is designed to support heavy-duty cranes, including those handling loads up to 100 tons.
- Lateral Stability: The wide base and low height increase the rail's structural rigidity, allowing it to withstand high lateral forces and reducing the risk of deformation.
Improved Wear Resistance and Longevity
- Material Strength: Frequently produced in high-strength steels like U71Mn, the rail boasts a high tensile strength of ≥ 690 N/mm².
- Reduced Deformation: The thick web (approximately 45 mm) reduces the chance of vertical and lateral deflection under heavy, repeated, or high-speed traffic, resulting in a longer operational life and lower maintenance requirements.
Performance in Specific Applications
- Dynamic Load Handling: The weight and robust structure make it ideal for high-start-stop environments such as steel plants, port cranes, and mining transport systems.
- Stability in Movement: The low center of gravity ensures smooth movement for cranes, reducing vibration and enhancing safety.
Optimized Economic Performance
- Ideal Middle-Ground: A75 strikes a balance between weight and strength, making it more cost-effective than heavier rail types (like A100 or A120) for medium-to-high capacity lifting applications.
DIN 536 A75 Rail Specifications
With a broad base width of 200 mm and a head width of 75 mm, the weight is concentrated in a way that maximizes the contact area with sole plates while providing a robust surface for crane wheels. This specific A75 profile geometry is why it is preferred for heavy duty crane rail applications over lighter railway profiles.

Frequently Asked Questions
- What is the exact weight per meter for A75 rail?
The a75 rail weight per meter is approximately 56.2 kg/m. This DIN536 A75 Rail Weight is the standard used for all technical and logistical calculations involving this profile.
- How does the weight of A75 compare to A65 rail?
The A75 crane rail is heavier than the A65, which weighs approximately 43.1 kg/m. The additional weight of the A75 profile provides higher load-bearing capacity for more demanding overhead cranes.
- Is the weight of the A75 rail the same for all material grades?
Yes, the A75 rail weight per meter remains approximately 56.2 kg/m regardless of whether you choose a 690, 880, or 1080 N/mm² A75 crane rail material grade, as the density of the steel remains virtually constant.
- Can you provide A75 rail in custom lengths to manage the total weight?
Yes, while the DIN 536 Standard A75 rail length is usually 12 meters, we provide End Processing & Finishing to cut the A75 steel rail to your desired length for easier handling and installation.
- Why is the base of the A75 rail so wide compared to its weight?
The 200 mm base of the A75 profile is designed to distribute the weight and downward pressure of the crane over a larger area, reducing the stress on the sole plates and the support structure.
- Does the A75 rail require specific clips due to its weight and size?
Absolutely. Because of the unique A75 Rail dimensions, specialized clips/A75 crane rail clips are required to securely clamp the wide base and ensure the rail remains stable under high lateral forces.
