What Is The Weight Specification Of A120 Rail?
The A120 rail (also known as DIN 536 A120 or DIN A120) has a theoretical or nominal weight of 100 kg/m (approximately 201.6 lbs/yard). This heavy-duty crane rail is manufactured according to the European Standard DIN 536 P1:1991.

GNEE RAIL utilizes precision rolling technology to ensure that the actual mass of our A120 rails aligns perfectly with the theoretical standards. By maintaining strict oversight of the metallurgical process, we guarantee that every batch of A120 steel rails meets the density and dimensional requirements of the European Standard DIN 536 P1:1991.
What are the weight advantages of DIN536 A120 Rail?
The DIN536 A120 rail is a heavy-duty crane rail designed for high-capacity industrial applications. Its weight advantages stem from a 100 kg/m (approximately 201.6 lbs/yd) nominal weight and a robust design optimized for stability, high load capacity, and durability under severe, continuous operation.
Weight Advantage Characteristics:
- High Unit Weight (100 kg/m): With a mass of 100 kg/m, the A120 provides a very stable base, reducing the risk of buckling or deformation under extreme vertical loads, such as those found in container terminals, steel plants, and shipbuilding yards.
- Optimal Load Distribution: The profile consists of a 120 mm head width and a wide 220 mm base. This configuration helps distribute heavy wheel loads over a larger area, reducing contact pressure and improving the longevity of the track and its substructure.

- Robust Web Structure: The web is 72 mm thick, providing superior vertical strength and stiffness compared to lighter rail profiles like the A100 (which has a 60 mm web and 74.3 kg/m weight).
- Reduced Deformation and Fatigue: Due to its massive section (a total cross-sectional area of 127.40 cm²), the A120 offers high resistance to lateral bending and fatigue, leading to lower maintenance costs over the rail's lifecycle.
What is the maximum axle load that A120 rails can withstand?
A120 crane rails, manufactured according to the DIN 536 P1:1991 standard, are heavy-duty rails typically used for high-frequency operations such as container terminals and heavy manufacturing, often supporting gantry and overhead cranes.
Maximum Load Capacity
- Crane Capacity: Under standard conditions (e.g., concrete strength ≥ C30, track gauge ≤ 10 m), A120 rails can support crane lifting capacities up to 320 tonnes.
- Axle Load: While the exact "maximum" depends on wheel diameter and speed according to DIN 15070 calculations, A120 rails are designed for high-stress applications.
- Operating Conditions: Proper installation, including the use of shock-absorbing rubber pads and high-strength clamps, is crucial for maintaining this capacity.
Frequently Asked Questions
1. Does the weight of A120 rail vary between different steel grades?
No, the A120 rail weight per meter remains approximately 101.2 kg/m whether you choose A120 DIN536 Grade S700 European Crane Rail or a higher S900 grade. The density of steel is nearly identical across these strength levels.
2. Why is the A120 rail heavier than standard railway rail of the same height?
The A120 rail profile is much wider than standard railway rails. Its 220mm base and 120mm head provide a large volume of steel, resulting in a higher weight per meter, which is necessary for the stability of A120 crane tracks.
3. What is the weight of the accessories for a 12-meter A120 rail?
The weight of A120 rail accessories (clips, pads, and soleplates) varies by design, but generally, the fastening system for a 12-meter segment adds approximately 150kg to 250kg to the total installation weight.
4. Can GNEE RAIL provide custom lengths to manage weight limits?
Yes, while 12m is the standard, we can cut A120 heavy rails to specific lengths to help meet on-site lifting constraints or shipping weight limits while maintaining the standard A120 rail dimensions.
5. How does the rail weight affect the choice of rubber pads?
The 101.2 kg/m dead weight of the A120 rails requires high-density, steel-reinforced rubber pads that can support the constant pressure without permanent deformation.
