A75 Crane Rail
A75 Crane Rail is a DIN 536 medium‑duty rail with a 75 mm head width, 85 mm height, 200 mm base width, and a mass of 56.2 kg/m. Manufactured from 900A/U71Mn grade steel, it delivers ≥880 MPa tensile strength and 260–300 HB hardness, offering excellent resistance to wear and plastic deformation under cyclic crane loads. Commonly supplied in 6–12 m lengths, A75 is the standard choice for heavy‑duty trolley tracks (ports) and plant floor crane rails (steel mills, fertilizer conveyors). Every rail ships with full traceability and a Mill Test Certificate.

What Are the Exact Dimensions and Weight of DIN 536 A75 Crane Rail?
A75 follows DIN 536 P1:1991. Its wide 200 mm base (wider than the 85 mm height) gives high lateral stability under crane wheel loads.

What Material Is A75 Made Of — and What Does "900A" Mean?
A75 is rolled from 900A grade steel. In China, the corresponding GB grade is U71Mn. Both are commonly used for heavy-duty rail applications, with a minimum tensile strength of 880 MPa for 900A. If your specification calls for 900A or U71Mn, send us the grade and we’ll check it against your requirements.

Typical Applications of A75 Crane Rail
01 — Port & Container Terminals
Trolley Tracks for Ship-to-Shore Cranes
A75 rail is commonly used as trolley track on ship-to-shore container cranes and ship unloaders. The rails are mounted along the crane boom and guide the trolley during loading and unloading operations.
Its rail profile and wear resistance make it suitable for frequent trolley movement in port environments.
02 — Industrial Facilities
Crane Runways & Material-Handling Tracks
A75 rail can be used for crane runways, floor tracks, and material-handling systems in steel mills, shipyards, mines, and manufacturing plants.
Typical applications include gantry cranes, casting equipment, conveyor cars, and other vehicles operating on fixed rail tracks.
Project example: A75 rails were supplied for conveyor car tracks in a fertilizer plant in Pakistan.
What Custom Processing Can You Get for A75 Rail?
A75 crane rails can be supplied with cutting, bending, end machining, and surface treatment to match your track layout and installation requirements.
- End Machining: Rail ends can be chamfered or precision-machined for accurate joint fitting and cleaner installation.
Bevel Cutting: 45° bevel cuts and other specified cutting angles can be produced according to project drawings.
- Trolley Rail Preparation:Short rail sections and matching components can be prepared for crane trolley tracks and transfer systems.
- Special End Fabrication: Rail ends can be machined to specified dimensions for welded joints and other structural connections.
- Rail Bending: Straight A75 rail can be formed into curved sections to match the required track radius and layout.
- Surface Protection: Sandblasting, painting, and hot-dip galvanizing are available for improved corrosion protection.
Processing can be arranged based on your drawings, rail dimensions, and installation requirements.
