A system comprising a cable held in suspension and a trolley traveling along the cable relies on a brake to control velocity and limit 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 at a rate to improve comfort of a rider and reduce acceleration forces (loads) on the trolley. |
