What Are The Standard Dimensions Of A120 Rail?
The standard dimensions of the A120 rail are defined by a head width of 120 mm, a base width of 220 mm, and a total height of 105 mm. According to international manufacturing standards, the web thickness is 30 mm, and the A120 rail weight per meter is approximately 101.2 kg/m. This "short and wide" profile is specifically engineered to provide maximum stability for heavy-duty crane systems and industrial tracks.
- Width of Head: At 120 mm, the wide surface allows for massive crane wheels to distribute weight effectively, reducing localized steel fatigue.
- Width of Base: The 220 mm base provides a low center of gravity, which is crucial for resisting the lateral (side) forces generated by moving overhead cranes.
- Total Height: A compact height of 105 mm minimizes the "tipping" leverage effect during high-torque crane movements, ensuring the A120 rail profile remains seated.
- Material Mass: With a weight of 101.2 kg per meter, the A120 rails offer the structural density required for high-tonnage industrial applications.
GNEE RAIL implements a rigorous quality management system that ensures every A120 steel crane rail produced in our facility strictly adheres to the dimensional accuracy required for complex infrastructure. Our integrated manufacturing approach ensures that each rail segment facilitates a perfect fit with standard fastening clips and rubber pads, providing a seamless, high-strength solution for your heavy-duty Crane Track requirements.
DIN 536 A120 Rail Dimensions
The following data represents the standardized Specifications of A120 Rail according to the European Standard DIN 536 P1:1991. These figures are critical for calculating the load-bearing capacity of the A120 rail system and for selecting the appropriate A120 rail accessories.
| Rail Type | Weight(Kg/m) | Material | Length(m) |
| A120 | 100 | 700/900A/1100 | 10-12 |
| Head Width(mm) | Bottom Width(mm) | Rail Height(mm) | Web Thickness |
| 120 | 220 | 105 | 72 |
Why does DIN536 A120 Rail use Base Design?
The distinctive geometry of the A120 rail-where the base width (220 mm) is more than double the total height (105 mm)-serves a critical mechanical function. This "low profile" design is a hallmark of European A sections low profile rails. Unlike traditional railway rails that prioritize vertical flexibility for high-speed travel, the DIN 536 A120 rail prioritizes rigidity and load dispersion.
The massive base width significantly increases the "footprint" of the rail on the baseplates/Steel Soleplates. This large contact area reduces the pressure (Force/Area) exerted on the supporting girder or concrete foundation. By spreading the weight of a 50-ton wheel load across a wider surface, the A120 steel rails prevent the crushing of rubber pads and minimize structural vibration. Furthermore, the thick web (30 mm) provides the shear strength necessary to handle the sudden braking and acceleration forces of heavy industrial cranes.
- Enhanced Stability: The wide base prevents the A120 crane tracks from tilting under heavy horizontal thrusts.
- Pressure Reduction: Maximizes the lifespan of the underlying DIN536 A120 Rail System components.
- Vibration Dampening: The mass and shape of the A120 heavy rails help absorb the acoustic energy of heavy machinery.
Frequently Asked Questions
1. What is the exact weight of A120 rail per meter?
The DIN A120 Rail Weight is officially listed as 101.2 kg/m. This mass is essential for structural engineers to calculate the total dead load on crane runways and ensure the supporting pillars can handle the combined weight of the rail and the crane.
2. Why is the A120 rail profile so much wider than a standard P50 rail?
The A120 rail profile is wider because it is designed for heavy "A" type cranes that generate massive side-thrust. A wider base provides a larger stabilization area, preventing the rail from shifting or rolling, which is a risk with taller, narrower standard rails.
3. How does the head width of 120 mm affect crane wheel selection?
The 120 mm head width of the A120 crane rail must match the tread width of your crane wheels. Usually, the wheel tread is slightly narrower or shaped to ensure optimal contact with the center of the rail head to prevent uneven wear.
4. Can I get A120 rail dimensions in custom lengths?
While the A120 rail dimensions are standardized in terms of cross-section, lengths can be customized. Most A120 heavy rails are supplied in 12-meter lengths, but they can be cut or welded using Alumothermic Welding kits for Rails to fit any track configuration.
5. What accessories are needed for a full A120 rail installation?
A complete DIN536 A120 Rail System requires baseplates/Steel Soleplates, elastic rubber pads, and adjustable standard fastening clips. These components ensure the rail stays within its dimensional tolerances even under thermal expansion and heavy loading.
