CR100 Crane Rail Applications
Container Terminal Crane Tracks
CR100 Rail is widely used in track systems for large lifting equipment at container terminals, such as ship-to-shore (STS) cranes and rail-mounted gantry (RMG) cranes. Due to the high wheel loads and frequent operation of this equipment, CR100 provides higher load-bearing capacity and better wear resistance, meeting the demands of continuous port operations.
Heavy-Duty Cranes in Steel Mills
In steel mills, molten steel cranes, charging cranes, and finished product handling cranes are constantly subjected to high temperatures, heavy loads, and impact loads caused by frequent starts and stops. With its large cross-sectional dimensions and excellent fatigue resistance, CR100 effectively enhances the stability and service life of rail systems.
Shipyard Gantry Crane Tracks
Gantry cranes in large shipyards are required to transport oversized components such as ship hull sections and heavy steel structures, placing high demands on the load-bearing capacity and operational precision of the tracks. CR100 Rail is suitable for such heavy-duty gantry crane tracks, ensuring that the equipment maintains excellent stability during long-term operation.
Bulk Cargo Terminals and Mining Handling Equipment
At bulk cargo terminals handling materials such as ore and coal, stacker-reclaimers, ship loaders, and large gantry cranes typically require prolonged continuous operation. CR100 is capable of withstanding high-frequency, high-load working environments, reducing rail wear and lowering maintenance costs.
Large-Scale Industrial Manufacturing Facilities
In industries such as heavy machinery manufacturing, wind power equipment manufacturing, and pressure vessel manufacturing, high-capacity overhead cranes require reliable running rails. CR100 meets the load-bearing capacity and operational stability requirements for the frequent lifting of heavy workpieces.
Advantages of Our CR100 Rail
Exceptional Load-Bearing Capacity
U71Mn steel with high tensile strength ensures resistance to bending or deformation, even under extreme weights.
Seamless Global Compatibility
Adherence to JIS standards guarantees alignment with international crane systems, simplifying cross-border project integration.
Optimized Wear Resistance
Precise 150mm height and 155mm base width ensure tight contact with crane wheels, minimizing friction and extending service life.
Enhanced Structural Durability
A 39mm thick web reinforces rigidity, reducing fatigue in high-frequency lifting and movement operations.
