[0002] Terminal conveyors are the application of conveyors in specific places. They transport materials from one end of a ship or terminal to the other through a certain conveying route, realizing the rapid loading and unloading and handling of materials. This equipment is widely used in logistics hubs such as ports and terminals, and is an indispensable and important part of the modern logistics system.

[0003] When existing terminal conveyors transport heavy materials, the roller components of the terminal conveyors are severely worn, so special personnel are required to regularly repair and replace the rollers.
