| 20110303115 | LOAD-MINIMIZING, TROLLEY ARRESTER APPARATUS AND METHOD - A system comprising a cable held in suspension and a trolley traveling along the cable relies on a brake to control velocity and net downhill acceleration of the trolley. The trolley may include a brake pad positioned to contact the cable. At the downhill end of the ride, the lever actuating the brake is caught and lifted by a capture ring, thus relieving the braking load on the trolley. Also, the trolley engages a comparatively modest, second resistance mechanism, such as, for example, a system of springs, that gradually increases in resistance with distance of motion of the trolley thereagainst, bringing the trolley to a gradual halt. | 12-15-2011 |
