Both CR73 and MRS87B / CR175 are produced using U71Mn high-strength manganese steel, known for its excellent toughness, wear resistance, and ability to withstand high wheel pressures. This makes the CR Series particularly well-suited for port cranes, gantry systems, and continuous-duty heavy lifting operations.
CR Series rails are manufactured using hot rolling processes to ensure precise dimensions and structural uniformity. They can be supplied in customized lengths (typically 6–12m) and are available with machining options such as:
Cutting & drilling
Welding and end shaping
Surface treatments (painting, galvanization, sandblasting)
These treatments extend the rail’s service life, especially in marine or corrosive environments such as ports and shipyards.
The CR Series is widely used in:
Container terminals and dockside crane systems
Shipbuilding and steel manufacturing plants
Heavy-duty gantry crane tracks
Specialized industrial lifting systems
Installation is typically done on steel beams or reinforced concrete bases using high-strength rail clips and pads to ensure stability, reduce vibration, and maximize rail longevity.
