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 A45 Rail System Solutions
Including Complete Rail Fastening Systems

DIN 536 A45 Rail Applications
→ Port Terminals
Used for the tracks of rail-mounted container gantry cranes (RTGs) and gantry crane maintenance trolleys. Typical capacity: 40.5 tons. This configuration has been successfully deployed in numerous container terminals worldwide.
→ Shipyards
Used for the travel tracks of medium-sized gantry cranes, suitable for shipbuilding gantry cranes with a lifting capacity of ≤ 200 tons. It has been adopted in large quantities for shipyard projects in Vietnam, Bangladesh, Indonesia, and other countries.
→ Industrial Plants
Used as travel tracks for 10–30-ton overhead cranes (bridge cranes), with spans up to 30 meters, meeting the daily material handling needs of steel and machinery manufacturing workshops.
→Warehouses and Logistics Centers
Used for shuttle and stacker crane tracks in automated high-bay warehouses, with a maximum wheel load of ≤ 8 tons. There are numerous application cases in logistics centers across Europe and the Middle East.
→ Heavy-duty Transportation
Used as dedicated railway tracks for heavy-duty flatbed trucks (trailers), with typical axle loads of 20–25 tons, suitable for material transfer routes within ports and steel mills.
Why Choose A45 Instead of Heavier Rails？
1. Technical Compatibility (Why A45 is Sufficient)
- Wheel Load and Load Class: A45 is suitable for cranes with small to medium wheel loads (typically ≤ 80–100 kN per wheel; refer to the manufacturer’s load chart for specifics). If the actual crane wheel load and duty class (e.g., M3–M5 in FEM/ISO standards) fall within the load-bearing range of A45, using heavy rail not only fails to improve performance but may also cause uneven distribution of wheel contact stress due to excessive rail stiffness.
- Deflection and Deformation Control: Lightweight rails impose lower requirements on the local stiffness of main girders and cantilevers. In steel-structured industrial buildings or light crane girder systems, A45 can deform in coordination with conventional-section girders, preventing rail gouging or bolt fatigue caused by the “rigid rail, flexible girder” phenomenon.
- Installation and Tolerance Adaptability: With its smaller cross-section and lighter weight, A45 imposes relatively less stringent requirements on track foundation flatness and embedded part precision, making on-site track alignment, welding, or bolted connections easier to control.
2. Full Life Cycle Cost-Effectiveness
Initial Costs: Costs for material procurement, transportation, hoisting, and fasteners (clamping plates/bolts) are significantly lower than those for heavy rails.
Maintenance Costs: A45 rails wear more slowly under moderate operating conditions, and the construction windows for replacement, grinding, and realignment are shorter, resulting in minimal downtime losses.
Indirect Structural Costs: There is no need to increase the cross-section of crane girders, reinforce column bases, or upgrade foundations to support heavy rails; overall civil engineering and steel structure investment can be reduced by 10%–25%.
3. Application Scenarios (When A45 is the Right Choice)
Service Class ≤ M5 (moderate frequency of use, not 24-hour continuous heavy-duty operation)
Wheel load ≤ 100 kN; lifting capacity typically ≤ 20–32 t (bridge/gantry cranes)
Facilities with moderate spans and crane girders made of standard welded H-sections or cold-formed thin-walled systems
Projects with budget constraints, short construction cycles, or potential future adjustments to process layouts
⚠️ When is an upgrade to heavier-duty rails mandatory?
Wheel load > 120 kN or service class ≥ M6 (heavy-duty/intensive operation)
Operating speed > 2 m/s or frequent starts, stops, and reversals
Track foundations consist of concrete cantilevers or heavy-duty steel structures, with a design life > 20 years
Must accommodate future crane capacity expansion (reserve 20%–30% load margin)
Quality Assurance & Inspection
All A45 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.
