Abstract
A trolley braking system for smoothly reducing the speed of a rider supported by a harness on a cable or rope approaching a landing platform comprises a cylinder having a closed end and a piston slidably mounted in the interior. A braking cable is secured to the piston and routed through an opening in the closed end of the cylinder to a braking block, which is slidably mounted on the cable between the trolley and the landing platform. The system may also may also include a relief valve to release compressed air from the cylinder, so that the braking force may be controlled.
