In large mining excavators, the pulleys (or pulley systems) are crucial transmission and load-bearing components, and they mainly enhance the performance and efficiency of the equipment through the following functions:

In mining machinery and equipment, large sprockets, as key transmission components, are widely used in high-intensity and heavy-load working conditions. Their design and application need to meet requirements such as wear resistance, impact resistance and long service life. The following are the main

Gears come in many different shapes and are widely used. Spur gears are the most common type of gears. They have straight teeth, and are mounted on parallel shafts. Sometimes, many spur gears are used at once to create very large gear reductions. Spur gears are used in Minging excavator，Crush
