What is the weight per meter for A120 rail?
The theoretical A120 rail weight per meter is officially 101.2 kg/m according to the DIN 536 Standard. This significant mass is a direct result of the rail's robust, wide-base geometry, which is engineered to provide maximum stability for heavy-duty crane systems.
- Massive Footprint: The weight is concentrated in a broad 220 mm base and a thick 30 mm web, allowing the A120 rails to absorb intense dynamic impacts from heavy crane wheels without structural fatigue.
- Engineering Load Calculations: At 101.2 kg/m, structural engineers use this figure to calculate the "dead load" of the track system. This ensures the supporting girders and baseplates/Steel Soleplates are rated to handle both the rail's weight and the crane's maximum lifting capacity.
- Material Density: While different Grades of DIN 536 Crane Rail (such as S700 or S900) offer different strength levels, the physical DIN A120 Rail Weight remains constant because the density of the high-quality steel used in the A120 rail material does not significantly change between grades.
- Shipping and Logistics: For procurement planning, a standard 12-meter length of A120 steel crane rail weighs approximately 1,214.4 kg, a critical factor for determining crane requirements during the installation of A120 overhead crane rail systems.
GNEE RAIL maintains precision manufacturing tolerances to ensure that every meter of our A120 heavy rails meets the strict weight and dimensional requirements of the European Standard DIN 536 P1:1991.
Why Is the A120 Rail Weight per Meter Important for Design?
The weight of the A120 rail profile is a primary indicator of its heavy-duty capabilities. In industrial design, the weight per meter directly correlates to the rail's moment of inertia and its ability to resist bending under pressure. Because the A120 steel rails weigh over 100 kg/m, they offer a much higher stiffness compared to lighter profiles(a100 rail,a75 rail,a65 rail,etc), which is essential for maintaining a level Crane Track under the extreme wheel loads of gantry cranes.
| DIN536 Crane Rail | Head Width (mm) |
Base Width | Rail Height | Waist Thickness | Nominal Weight (kg/m) |
|---|---|---|---|---|---|
| A45 | 45 (±0.6) | 125 (+1.5, -3) | 55 (±1) | 24 | 22.10 |
| A55 | 55 (±0.6) | 150 (+1.5, -3) | 65 (±1) | 31 | 31.80 |
| A65 | 65 (±0.8) | 175 (+1.5, -4) | 75 (±1) | 38 | 43.10 |
| A75 | 75 (±0.8) | 200 (+2, -5) | 85 (±1) | 45 | 56.20 |
| A100 | 100 (±1) | 200 (+2, -5) | 95 (±1.5) | 60 | 74.30 |
| A120 | 120 (±1) | 220 (+2, -5) | 105 (±1.5) | 72 | 100.00 |
Furthermore, the A120 rail weight per meter influences the selection of the fastening system. Heavier rails generate more significant thermal expansion forces; therefore, the A120 rail accessories, such as clips and Alumothermic Welding kits for Rails, must be robust enough to manage the mass of the rail while allowing for necessary longitudinal movement.
Selecting a rail with the correct mass ensures that the supporting structure is not over-engineered (saving costs) or under-engineered (risking safety).
Frequently Asked Questions
1. Does the weight of A120 rail change if I choose a higher steel grade?
No, the DIN A120 Rail Weight of 101.2 kg/m is based on the volume of the A120 rail profile and the standard density of steel. Choosing a higher grade like A120 DIN536 Grade S700 European Crane Rail improves strength and hardness, but the weight remains the same.
2. Why is the A120 rail so much heavier than a standard railway rail of similar height?
The A120 heavy rails are much wider than standard railway rails. The 220 mm base and 120 mm head add significant volume and mass to the profile, which is necessary to handle the slow, heavy crushing forces of cranes rather than high-speed train traffic.
3. Can GNEE RAIL provide custom lengths to manage shipping weight?
Yes, while 12 meters is standard, we can manufacture A120 steel crane rail in custom lengths to suit your shipping container limits or on-site lifting capacities, provided they align with the overall DIN 536 A120 rail dimensions details.
4. How does the weight of the rail impact the choice of rubber pads?
The heavy weight of the A120 rail profile requires high-density, steel-reinforced rubber pads. These pads must be strong enough to not flatten permanently under the 101.2 kg/m dead weight plus the active load of the crane.
