Abstract
Improvements in a braking system for a zip line are presented. Braking occurs when a zip line rider makes contact with a braking carriage that slides along the zip line. The braking carriage pulls on a rope. The rope pulls on a length of chain in a chain reservoir to slide and lift the claim through the chain reservoir. The chain reservoir is an elongated tube that is mounted at an angle. As the zip liner moves further into the landing platform they lift a continuing greater amount of chain from the chain reservoir. The angle of the chain reservoir, coefficient of friction between the chain and the chain reservoir affects the pull-back. After the zip liner comes to a complete stop they remove the carriage from the zip line and gravity returns the brake mechanism. Minimum pull-back makes removal of the cable trolley easier.
