A120 Rail
Product Overview
A120 rail (also referred to as the A120 Crane rail) is a heavy-duty crane rail designed to DIN 536 P1:1991. With precise structural design and excellent mechanical performance, it serves as a core load-bearing component in high-intensity environments such as ports, steel and metallurgical plants, and heavy manufacturing. Its nominal weight of 100 kg/m and wide-base profile deliver outstanding stability and load transfer capability, providing a reliable foundation for safe, efficient crane operation.
Core advantages
Exceptional load capacity and stability: The 220 mm wide base and 72 mm thick web, together with the 100 kg/m mass, distribute stresses effectively under both trolley and crane wheel loads, reducing lateral bending and ensuring smooth crane travel for the A120 rail.
Superior wear and fatigue resistance: Made from U71Mn rail steel and produced by hot-rolling followed by precision heat treatment, the rail head reaches a Brinell hardness of HBW 260–300, resisting long-term wear from repetitive crane traffic and offering excellent fatigue life.
High compatibility and safety: Manufactured to the strict dimensional tolerances of DIN 536, the rail head, web, and base are held to tight tolerances for reliable compatibility with DIN-standard fastenings and connectors. Surface finishing removes cracks and laps to prevent stress concentrations.

Typical applications
Ports & terminals: Running rails for container gantry cranes and quay cranes, capable of withstanding multi-hundred-ton loads and corrosive, marine environments.
Steel & metallurgy: Rails for ladle cranes, blast furnace cranes and other high-temperature, heavy-load equipment; resistant to thermal radiation and material impact.
Mines & heavy manufacturing: Rails for hoists, heavy machine tool travel ways, and large assembly-shop cranes—maintaining positional accuracy in harsh operating conditions.
Quality assurance & service commitment
We employ a full-process quality control system—from selection of U71Mn steel billets through hot-rolling and precision finishing—using professional inspection equipment to verify dimensional accuracy and mechanical properties at every step. Each A120 rail undergoes tensile testing, hardness testing, and surface-defect inspection prior to shipment; third-party test reports are available on request.
We also offer customized services including rail cutting, drilling, supply of matching connectors and fastenings, and on-site installation support from our technical team to ensure optimal system performance.
FAQs
Q:Does the A120 crane rail support customized production?
A:Yes. We can customize special lengths (6 m–30 m), 45° cutting, special materials (low-temperature or corrosion-resistant alloys), and surface-strengthening treatments (quenching, chrome plating).
Custom lead times depend on product specifications and are typically 15–30 days; feasibility should be confirmed in advance with the technical department.
Q:What is the product warranty period?
A:Under normal operating conditions and correct installation, the product warranty period is 12 months. Within the warranty period, if the product fails due to substandard material or manufacturing defects, free replacement or repair will be provided.
Damage caused by human factors, overloading, improper installation, and other non-quality issues are not covered by the warranty; paid repair services are available for such cases.
Q: What is the maximum lifting capacity the A120 crane rail can accommodate?
A:Under standard installation conditions (track gauge ≤ 10 m, concrete foundation strength ≥ C30), the A120 crane rail can stably accommodate lifting equipment with a lifting capacity of ≤ 320 tonnes.
Actual suitability must be calculated based on a combination of working-condition parameters such as track gauge, operating speed, and braking frequency. We recommend a customized selection be provided by professional technical personnel.
