  • Publication number: 20110303115
    Abstract: 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.

  • Patent number: 7966941
    Abstract: An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable (8) as seen in FIGS. 1A and 1B. The trolley comprises front and rear pulleys (44F) and (44R) conjoined via pulley housing (16) with left and right horizontal handles (10L) and (10R) attached to vertical shaft (12). Front and rear hand brake levers (20F) and (20R) are mounted onto left and right horizontal handles (10L) and (10R). When front and rear hand brake levers (20F) and (20R) are squeezed by the rider, they create a constricting force on front left and right calipers (32FL) and (32FR) along with rear left and right calipers (32RL) and (32RR) of FIGS. 2A and 3A. Thus, friction is applied to front and rear pulleys (44F) and (44R) via front left and right brake pads (34FL) and (34FR) along with rear left and right brake pads (34RL) and (34RR).

  • Patent number: 7381137
    Abstract: Braking and motion-arrest apparatus for braking the arrival of a zipline cable rider at a landing platform and arresting the rider's motion to retain the rider at the platform. A frame is mounted on the cable to allow longitudinal rolling movement of the frame along the cable. A self-closing one-way latch is provided at the forward end of the frame. The latch includes a pair of capture plates which are normally inwardly biased toward one another, on opposite sides of the cable. The rider is tethered to a pulley block which rolls along the cable and collides with the latch. The collision force drives the plates laterally away from the cable, allowing the pulley block to roll through the latch. After the pulley block rolls past the latch, the plates' normal biasing closes the latch, preventing the pulley block from rolling back through the latch.

  • Patent number: 5660113
    Abstract: A support system that allows skiers and snow boarders to descend from cliffs and other elevated surfaces while eliminating the high speed impact landing after the descent. Aerial cables (10 and 12), suspended between towers (14 and 16), provide a path for transporting pulleys (18 and 20). Attached to pulleys, support lines (22 and 24) gradually carry the skier in harness (26) towards landing area (32) after the skier experiences a limited free-fall. While skiing down launch area (28), break-away attachments (46 and 48) keep the pulleys in the same plane as the sider and also retain partial slack in the support lines until free-fall begins. After siding from edge of ramp (30), the skier's weight pulls on the support lines causing the break-away attachments to release the partial slack held in each support line. The sider is in free-fall for a distance predetermined by the length of slack in the support lines.
