The crane rail can use square steel, railway steel rail and crane steel rail.
Square steel is usually used for cranes with small lifting weight, slow running speed and low working frequency. The material is killed steel Q345B.
Railway rails are mostly used for train tracks, and can also be used for medium-sized crane tracks. They have strong load-bearing capacity, stable performance, and high cost performance. The material is 55Q.
Crane rails are mostly used for heavy-duty cranes. They have strong load-bearing capacity and stable performance. After adding Mn, Si and other alloy elements, the wear resistance and corrosion resistance are improved.
