A75 Rail
Product Overview
A75 Rail (also called as A75 Crane Rail) is a DIN-certified, heavy-duty crane rail engineered for continuous, high-load operations in ports, steelworks and heavy manufacturing. With a wide 200 mm base and hardened 75 mm rail head, the A75 Rail delivers exceptional lateral stability, wear resistance and long service life — making it a cost-effective choice for 50–100-ton cranes and beyond.
A75 Rail dimensions
Rail head: 75 mm
Rail height: 85 mm
Rail base width: 200 mm
Mass: 56.2 kg/m
Standard length: 12 m (custom 6–12 m available)

Typical Applications
Ports & Shipyards: Container gantry cranes, heavy lifting in marine environments (optional corrosion protection for salt spray).
Metallurgy & Foundries: Hot‑work cranes and slab/ingot handling where temperatures and dust are high.
Heavy Manufacturing: Bridge and overhead cranes for heavy assembly (precision positioning ±5 mm achievable).
Construction & Civil Works: Temporary rails for tower cranes, dam gates and portal cranes — reusable and quick to install.

Installation & Maintenance
Installation notes:
Align modules with DIN tolerances and fasten with fishplates. Follow manufacturer torque and grading for anchor bolts.
Under typical conditions, 2–3 trained installers can install and commission approximately 100 m of A75 Rail.
Maintenance checklist:
Daily: Clear debris from rail surface; spot‑check for visible damage.
Monthly: Lubricate connection points and check fastener torque.
Annually: Professional survey for straightness and wear. Replace or repair when wear depth exceeds 3 mm on critical running surface.
Why choose the A75 Rail?
Proven Standards — Manufactured to DIN 536 P1:1991, compatible with ISO and GB standards for smooth international procurement and certification.
Exceptional Load Capacity — Wide 200 mm base for outstanding lateral stability. The A75 Rail supports 100+ tonnes on a single rail and resists up to 250 kN lateral load — ideal for 50–100‑ton cranes.
Longer Service Life / Lower Lifecycle Cost — Available as A75 Crane Rail in U71Mn high‑carbon steel. Rail head hardness ≥ 260 HB after special heat treatment; wear reduced by ~50% vs. conventional rails, extending service life beyond 15 years.
High‑Temperature Options — Selectable heat‑resistant grades rated up to 400°C for metallurgical environments.
Fast, Global‑Ready Installation — Modular design and standard fixings allow straightforward direct or indirect mounting; 2–3 installers typically complete 100 m of track installation and commissioning under normal conditions.

FAQs
Q:Is weld repair possible when wear exceeds limits?
A:Local weld build‑up and re‑heat treatment can extend service life in non‑critical sections; however, for primary load paths it is safer to replace the rail segment.
Q:Are third‑party material tests available?
A:Yes — factory test reports are included; third‑party inspection can be arranged per project requirements.
Q: What quality inspection reports can you provide?
A:The delivery includes a material test certificate, hardness test report (rail head ≥260 HB), and dimensional inspection report. Third-party inspection can be arranged according to project requirements (additional fees apply).
