What Is a DIN 536 A75 Crane Rail?
The A75 crane rail is a heavy-duty steel rail profile manufactured according to the European standard DIN 536-1:1991. It is specifically designed to support crane runway tracks rather than regular railway transport.
This profile features a characteristically wide base, a lower overall height, and an extra-thick web. This geometry ensures a low center of gravity, allowing the track to distribute huge vertical wheel loads evenly and resist strong lateral forces caused by the acceleration, braking, and crab walk of heavy gantry cranes.
- Designation "A75" = 75 mm top head width
- Wide base for even vertical wheel-load distribution
- Resists lateral forces from crane acceleration, braking & crab walk

Manufacturing Tolerances (DIN 536 Compliance)
Our factory strictly controls geometric deviations within these thresholds to guarantee seamless on-site installation and prevent excessive wheel flange wear.
DIN 536 A75 vs. Larger Profiles (A100 / A120)
DIN 536 A75
Optimized for moderate-to-heavy wheel loads, typically up to 300–350 kN depending on crane speed and rail material.
Highly cost-effective profile for standard container handling and indoor factory runway girders.
DIN 536 A100 / A120
Designed for ultra-heavy duty applications with wheel loads exceeding 450 kN.
Used in massive ship-to-shore (STS) cranes and heavy shipyard gantry systems.
Selection Tip: If your system operates under high-frequency cyclic loading, upgrading the steel grade (e.g., from 50Mn to U71Mn) on an A75 track is often a more economical choice than upsizing to an A100 profile.
Chemical Composition & Mechanical Properties
| Steel Grade | Standard Basis | Tensile Strength (Min) | Hardness (HB) | Recommended Application |
|---|---|---|---|---|
| U71Mn | GB/T 2585 | 880 MPa | 260 – 300 | Standard industrial workshops, overhead cranes, steel mills |
| 900A | BS 11 / UIC 860 | 880 MPa | 260 – 300 | High-frequency automated warehouses, international port runways |
| 50Mn | GB/T 699 | 645 MPa | 200 – 240 | Light-duty crane systems, maintenance tracks, low-frequency lines |

Frequently Asked Questions
What does "A75" mean in the DIN 536 standard?
The letter "A" specifies the standard flange-based, flat-bottomed crane rail family. The number "75" indicates the exact width of the top rail head, which is 75 mm. It does not represent the weight or total height of the profile.
Can your factory cut the rails to custom lengths for container loading?
Yes. While the standard factory production length is 12 meters, our processing factory regularly cuts the rails to customized lengths, such as 11.8 meters, to fit standard 40ft ocean containers. This significantly lowers sea freight costs and simplifies inland logistics.
Do you supply the matching rail clips and rubber pads for the A75 model?
Yes. We supply the complete turnkey track assembly package. All our weldable/bolted clips and elastic rubber pads are engineered to match the exact foot width (200 mm) and head characteristics of the DIN 536-1 A75 profile, preventing mismatched components on-site.
