Product Introduction
GB crane rails are rail systems customized for the tread curvature of crane wheels. The radius of curvature of the rail head arc matches the radius of curvature of the wheel tread by 1.1-1.3 times, which effectively reduces the contact stress concentration. Combined with the surface roughness control of 0.2-0.5mm on the rail top, it reduces running resistance and wear.
The specifications of QU120 steel national standard U75V rails are precise and unique. The width of the rail head ensures good contact with the crane wheel, effectively disperses the pressure transmitted by the wheel, and reduces local stress concentration; the wider rail bottom and higher rail height, combined with the thick waist, greatly enhance the overall stability and load-bearing capacity of the rail. The theoretical weight per meter is about 118.1kg. The larger weight enables the rail to maintain a stable state when subjected to huge dynamic and static loads, and is not prone to displacement and deformation, providing a solid foundation for the smooth operation of the crane.
The QU120 rail made of U75V material exhibits excellent mechanical properties. Its tensile strength is greater than or equal to 980MPa. Compared with some ordinary rail materials, it has a higher strength reserve and can withstand greater tensile forces. During the process of frequent crane lifting of heavy objects, it effectively prevents the rail from breaking due to excessive tensile forces.
