Crane Rails
Crane / Hoist Rails are engineered for crane runways and hoisting bridges where stability, predictable wheel-to-rail contact and dimensional precision are critical. We supply industry-standard profiles (A45, A65, A75, A100，A120，A150 or equivalents) with options for pre-machining, drilling, welding, protective finishes and on-site installation support, backed by mill test certificates and QA documentation.

Key Advantage
- Optimised contact area & stability — profiles such as A45, A65, A75, A100, A120 and A150 (or equivalents) are engineered to provide broad wheel-rail contact, reduced local stress and predictable wear behaviour.
- Load-centric design — sections selected to support concentrated wheel loads and dynamic impact from cranes and hoists.
- Precision geometry — tighter dimensional tolerances for accurate alignment of crane runway and bridge travel.
- Compatibility — widely used industry profiles with available spare sections, joints and accessories for easy replacement.
- Customisation & finishes — supplied cut-to-length, pre-machined, drilled or pre-welded to suit runway brackets and end-stops; coatings and surface hardening available on request.
- Traceability & QA — material certification (MTC), dimensional inspection and NDT reporting available per order.
Typical applications
Stockyard stacker/reclaimer gantries — large gantry rails that carry stacker-reclaimers for piling and reclaiming ore (iron ore, coal, bauxite) in open-pit and port stockyards.
Shiploader / berth gantries — heavy shiploader gantries and mobile berth cranes at mine export terminals rely on A-type rails for smooth, continuous travel while loading bulk carriers.
Workshop & maintenance cranes on mine sites — heavy overhead cranes in maintenance shops, locomotive depots and shovel/rotary-drum workshops used for lifting engines, gearboxes and bucket assemblies.
Crusher/feeder bridge cranes — cranes servicing primary/secondary crusher halls and conveyor transfer stations for routine maintenance and replacement of wear parts.
Wagon tipplers / wagon handling bridges — rails for the travelling bridges and trolleys that position and tip ore wagons at load/unload facilities.
Port rail-mounted gantries (RMGs) and transfer cranes used where mines interface with port logistics — often heavy-duty QU-type rails to support continuous, high-load operation.
Installation & maintenance recommendations
Check: profile, lengths & MTCs.
Lift/Store: use spreader bars; store on level skids.
Mount: level seats, correct bolts & torque; use shims, don’t bend.
Jointing: weld for continuous runs; fishplates/bolts for replaceable sections.
Test: low-speed roll test, then re-check bolts & alignment.
Daily: quick visual for loose bolts, debris, damage.
Periodic: torque checks, wear inspection, NDT at critical points.
Repair: certified welders only; replace cracked/worn sections.
Safety: isolate crane, follow hot-work permits, use PPE.
FAQs
Q: What jointing method is recommended for crane rails?
A: For minimal maintenance and continuous travel, welded joints (shop welds or thermite/flash-butt) are preferred. Bolted joints with fishplates are acceptable for replaceable sections; ensure correct bolts, clamp force and regular torque checks.
Q: Are special steel grades required for crane rails?
A: Standard industrial crane rails are manufactured to grades suitable for high contact stress and wear; specific grade selection depends on operating environment, fatigue and impact exposure. We can supply standard grades or alternative materials on request — please specify environment and duty.
Q: Can you supply short lead-time replacements for emergency failures?
A: Yes — subject to stock and logistics. For critical runways we recommend maintaining spare lengths on site or with a local warehouse.
