Function of track chains?

Track chains are an essential component of tracked vehicles, such as bulldozers, excavators, and tanks. They are responsible for transferring power from the vehicle's engine to the tracks, allowing the vehicle to move over rough terrain and perform heavy-duty tasks. Track chains also help distribute the vehicle's weight evenly across the tracks, providing stability and traction. Additionally, track chains help protect the tracks from wear and tear, extending the lifespan of the vehicle.
