Trolley braking system |
摘要 |
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. |

1. A braking system for a trolley which suspends and transports a rider on a cable to a landing platform comprising:
a cylinder having a closed end and a piston slidably mounted in the interior, the cylinder fixedly mounted to a support proximate the landing platform; a braking cable secured to the piston, the braking cable routed through an opening in the closed end of the cylinder; a relief valve in pneumatic communication with the cylinder configured to be opened by movement of the braking cable as the piston approaches the closed end of the cylinder; and a braking block slidably mounted on the cable between the trolley and the landing platform, the braking block connected to the braking cable. |
