Glory Rail Custom Processing Services
Designed according to DIN 536 A-series crane rails (A45, A55, A65, A75, A100, A120) are ideal for port cranes, overhead cranes, and heavy-duty conveyor systems. We offer tailored processing services to adapt each rail to your installation and project needs.
End machining: Rail ends are chamfered or precision-milled to improve joint fit and eliminate edge damage during wheel transition.
Curved rail forming: Cold or hot bending is applied under controlled stress conditions to achieve stable alignment for curved track sections.
Trolley rail preparation: Short rail sections and matching accessories are prepared for crane trolley systems used in port and heavy-duty handling applications.
Bevel cutting: Non-standard cutting angles, including 45° and project-specific geometries, are produced to suit complex installation layouts.
Surface protection treatment: Sandblasting, painting, or hot-dip galvanizing is applied to improve corrosion resistance in outdoor and marine environments.
Special end fabrication: Rail ends can be manufactured according to drawings for welded joints or custom structural connections.
With decades of engineering experience in rail manufacturing, Glory Rail focuses on delivering precision-engineered crane rail systems designed for demanding industrial applications. Operating under established DIN and EN specifications with ISO-certified quality management, we integrate controlled steel processing and in-process inspection to ensure consistent dimensional accuracy, mechanical performance, and long-term operational reliability.
DIN 536 A120 Rail System Solutions
Including Complete Rail Fastening Systems
- Crane Rail Clips: Custom-made for DIN 536 A120 rails, these high-strength clamps deliver superior vibration resistance. Ideal for gantry and overhead crane tracks, suitable for gauges ranging from 600mm to 1520mm.
- Rubber Pads: Shock-absorbent and anti-aging rubber pads reduce noise, cushion impact and protect rails for all crane applications.
- Steel Soleplates: High-quality steel soleplates provide rigid support, evenly spread loads and avoid structural deformation.
- Rail Aluminothermic Welding Kits: Complete aluminothermic welding kits for crane rail installation. It creates high-strength, fatigue-resistant rail joints via exothermic reaction. No complex power required, enabling fast on-site installation for heavy-duty crane rails.
Rail System Integration Support
Technical support available for rail selection, fastening design, and installation planning for DIN 536 systems.
DIN 536 A120 Rail Applications
Ports and Container Terminals
Running tracks for shore-based container cranes (STS) and rail-mounted gantry cranes (RMG). A120 is commonly selected for STS with lifting capacities of 65 t or more; its wide base effectively distributes wheel load, reducing the risk of fatigue in the terminal’s front-of-dock beam structures.
Steel Smelting and Foundry Workshops
Foundry cranes and charging cranes are used to transport ladles of molten steel or tanks of liquid metal, with single-wheel loads often exceeding 500 kN. After heat treatment, the surface hardness of A120 rail heads can reach HB 260–340, providing superior resistance to indentation compared to standard hot-rolled rails.
Shipyard Dry Docks
Large gantry cranes lift ship hull sections (weighing hundreds of tons each). Tracks are laid on the dry dock floor or on track beams; the wide flange and bending stiffness of A120 help reduce uneven settlement.
Hydropower and Heavy Industry Facilities
Heavy-duty overhead cranes in hydropower plant installation bays are used to hoist components such as generator rotors and turbine runners. The tracks must maintain high straightness even under low-frequency use; A120 is often used in conjunction with elastic pads and embedded bolts.
Automated Storage and Retrieval Systems (AS/RS)
For high-lift stacker cranes with heights exceeding 20 m, the ground tracks must withstand high-speed starts and stops (acceleration typically ≥0.5 m/s²). The wear resistance and lateral stability of A120 meet the requirements for a long service life.
Temporary Heavy-Duty Construction Tracks
Used for temporary travel paths for heavy-duty tower cranes or gantry cranes at construction sites for dams, bridges, or super-high-rise steel structures. Track connections are primarily welded, with section lengths generally set at 12 m.
Why Choose A120 for Heavy Wheel Loads？
1. Geometric Advantages
- Wide base design: A base width of 220 mm combined with a height of just 105 mm creates a “short and wide” cross-section.
- Low center of gravity for roll resistance: Compared to traditional railway rails, this design significantly enhances resistance to lateral overturning.
- 72mm-thick web: Provides exceptional shear and bending resistance
2. Load Distribution Mechanism
- 100 kg/m mass: The track itself acts as a structural beam to distribute loads, preventing concentrated stress damage to the foundation
- 120mm rail head width: Provides a wide wheel contact surface, significantly reducing Hertzian contact stress
- Lateral Stability: A 220mm-wide base resists the massive horizontal thrust generated during crane acceleration and deceleration
3. Material Properties
- Multiple Grade Options: S700/S900/S1100 (or 50Mn/900A/U71Mn), tensile strength ≥880 N/mm²
- Wear Resistance: The S900 grade offers higher surface hardness than S700, making it suitable for high-frequency applications
- Dynamic Impact Absorption: A mass of 100 kg/m effectively absorbs dynamic impacts, maintaining rail alignment
4. Application Scenarios
The A120 is specifically designed for operating conditions that exceed the limits of the A100:
- Quay cranes at container terminals handling loads of hundreds of tons
- Continuous heavy-load cycles in heavy manufacturing workshops
- High-frequency operations at bulk cargo handling facilities

Quality Assurance & Inspection
All A120 crane rails are manufactured to DIN 536-1:1991 (≥690 N/mm²). Each rail undergoes ultrasonic testing (UT), magnetic particle inspection (MPI), and visual check. Mill Test Certificate EN 10204 Type 3.1/3.2 is available. Full traceability via heat number. Third-party inspection (SGS, BV, TUV) is welcome at any stage.
