Anti-Rollback for Zippey

The Anti-Rollback Cam is a simple device that can be mounted on the back of the Zippey Clip’n’Zip Trolley. In normal operation, the cam retracts, allowing the trolley to roll forward unhindered. However, as soon as the trolley starts to roll backward, the Rollback Cam is activated, immediately bringing the trolley to a halt. This anti-rollback function arrests the trolley’s progress, meaning that even if the trolley does not reach the end of the Zipline, it cannot roll backward, significantly reducing the rescue distance (and thus rescue time).
