JIS Cr73 Steel Rail
The JIS CR73 Steel Rail is a Japanese-standard, heavy-duty industrial rail profile engineered primarily for heavy crane hoisting runways, overhead/gantry cranes, and specialized industrial transport tracks. Weighing approximately 73.30 kg/m , the rail is designed to support high static loads and absorb repeated impact forces in demanding environments such as port terminals, factory workshops, shipyards, and large mining operations.
GNEE RAIL supplies CR73 rails with matching fastening systems and export support worldwide.

JIS Cr73 Steel Rail specification
Manufactured to Japanese Industrial Standards JIS E1103-91 (crane rails) and JIS E1101-93 (flat bottom rails), the CR73 profile features a distinctive, wide-head geometry (140 mm head width vs. 100 mm base width). This design provides an expanded contact surface for crane wheels, distributing heavy vertical wheel loads and preventing premature rail deformation.
