Key Features and Benefits
The CR73 Crane Rail’s high mass and adherence to the ARCELOR standard make it a top choice for the most demanding applications.
- Ultimate Load-Bearing Capacity: With a calculated mass of 73 kg/m, this rail provides superior stability and an enormous load-bearing capacity. It is specifically engineered to handle the intense concentrated loads from the heaviest cranes and industrial machinery.
- Specialized CR Profile: This rail’s specific profile is designed for optimal performance in heavy-duty applications, often featuring a base and head geometry tailored for particular types of crane wheels and high-stress environments.
- ARCELOR Standard: Manufacturing to the ARCELOR standard ensures top-tier quality and metallurgy. This standard guarantees the rail’s physical properties and dimensional tolerances, which are critical for safety and operational efficiency in high-stress environments.
- Exceptional Durability: The rail’s robust profile and premium steel composition provide superior resistance to wear, rolling contact fatigue, and deformation, even under continuous, intense use.
Applications
The CR73 Crane Rail is essential for a number of high-load industrial and mining uses:
- Stacker/Reclaimers: It provides a stable and durable track for these massive machines used for bulk material handling at ports and in mining operations.
- Steelworks Cranes: This rail is the ideal choice for cranes in steel mills that handle ladles of molten metal and other immense, high-temperature loads.
- Port & Wharf Cranes: It’s a key component for cranes at ports and wharves, where it must withstand the immense weights of container and bulk cargo handling.
- General Crane & Mining: It’s also used for specialized tracks in mining and other industrial applications where a robust and reliable rail is required for heavy machinery.
