Mechanics

The anti-rollback system

A chain lift is propelled by one or two motors located under the lift hill. As the motor turns, it moves the chain. When the train enters the lift hill, the chain dog attaches to the holes in the chain, and it propels the car forward.The anti-rollback device is the clicking noise found on most roller coasters as they ascend the lift hill.
