MRS87A Crane Rail
The MRS87A crane rail is a heavy-duty steel profile, specifically engineered for high-load, high-traffic crane and gantry systems. This robust rail is part of the German Rail Standard (MRS) series, known for its exceptional strength and durability in demanding industrial environments. With a nominal weight of approximately 87 kg per meter, its substantial cross-section and precise dimensions ensure superior stability and load distribution, making it an ideal choice for critical applications where heavy lifting and continuous operation are paramount. It provides a reliable and long-lasting foundation for large cranes, ensuring safe and efficient material handling.

Key Features and Benefits
The MRS87A crane rail’s design is optimized for maximum performance and longevity in heavy industrial applications.
- Heavy-Duty Profile: The substantial mass per meter and robust construction provide exceptional load-bearing capacity, crucial for supporting the immense weights and dynamic forces exerted by large industrial cranes.
- High Strength Material: Manufactured from high carbon steel, the MRS87A offers superior wear resistance and durability, extending the lifespan of the rail even under constant heavy use and abrasive conditions.
- Optimal Load Distribution: The wide base and precisely engineered head profile ensure even distribution of wheel loads, minimizing stress on supporting structures and enhancing the overall stability of the crane system.
- Precision Manufacturing: Produced to strict MRS standards, these rails offer excellent straightness and dimensional accuracy, which is vital for smooth crane operation, reduced wear on wheels, and improved safety.
Applications
The MRS87A crane rail is an indispensable component in various heavy industrial settings where robust and reliable crane tracks are essential:
- Ports and Shipyards: Provides tracks for giant gantry cranes used in container handling and shipbuilding, enduring heavy loads and harsh marine environments.
- Steel Mills and Metalworking Plants: Supports overhead cranes for transporting molten metal, heavy slabs, and finished products, operating under extreme temperatures and pressures.
- Manufacturing and Assembly Plants: Used for large overhead cranes and automated material handling systems that require high precision and durability for moving heavy machinery components.
- Warehouses and Logistics Hubs: Ideal for heavy-duty automated storage and retrieval systems (AS/RS) and gantry cranes that manage large inventories and heavy palletized goods.
