  • Patent number: 8333155
    Abstract: A trolley for traveling along a cable may include a frame having a first end, a second end, and a rail extending therebetween. A user may suspend from the frame in a harness, leveraging the user's weight about a fulcrum suspended by a sheave rolling along the cable. Opposite the user, across the fulcrum, a brake shoe or pad pivotably connected to the frame may be controlled by a user shifting weight, a trim brake adjustable by the user, or both to control a braking force generated by the trolley between the brake pad and the cable. Trim braking may be set to stop the trolley on any incline, roll with a constant braking bias, or roll freely. User-weight leveraging may be dynamically adjusted by a user likewise by selectively weighting a harness, weighting a handle and tether to draw the user's weight toward the fulcrum, or both.

  • Patent number: 8240254
    Abstract: A system comprising a cable held in suspension and a trolley traveling along the cable. The trolley may include a brake pad positioned to contact the cable. The brake pad may include a plurality of segments contacting the cable. A first such segment may be formed from a first material. A second such segment may be formed from a second material, distinct from the first material. The sequence, composition, gaps, and the like of the plurality of segments may be selected to provide a desired resistance to wear, frictional coefficient, all-weather braking, and the like.
