In production lines across various industries, rollers are one of the means used for transferring and moving products and raw materials. They are widely used in section rolling, melting, and steelmaking industries, playing a significant role in the movement of products such as rebar, beams, tubes, and profiles, as well as raw materials such as billets, slabs, and other materials including pellets, coal, and direct reduced iron (DRI), through indirect handling.

This system is driven by electric motors through belts and pulleys or chain sprockets, which rotate the rollers and enable the transportation of various products and materials throughout the production line. The selection of the motors and the calculations related to the belts and chains were carried out prior to the manufacturing stage. The manufacturing and assembly operations were then performed by the specialists at Jahan Sanat Kermanshah Company.
