A mechanical system for transmitting rotary motion and torque from one shaft to another using an endless chain. The chain links mesh precisely with the teeth of driving and driven sprockets, ensuring a positive, non-slip power transfer. They excel in high-torque applications where shafts are too far apart for gears but require exact synchronization, though they require regular lubrication and tensioning.

The conveyor uses a heavy-duty chain drive that needs tensioning every hundred operating hours.
