  • Patent number: 10500509
    Abstract: A cable in suspension (clear span) supports a trolley. At the upper end, a launch block fixed to the cable registers the trolley in all directions, including a safety release link holding the trolley near the launch block. After release and descent with a rider, the trolley strikes an attenuator of distributed springs and spacers. The spring stack absorbs momentum from the trolley, but a leash limits recoil “bounce” after reversing the trolley. A second, recoil, leash resists recoil by capturing a subset of the springs between respective ends of itself and the first leash. The doubly leashed trolley will oscillate to a stop in an equilibrium position.

    Abstract: An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable. The trolley comprises front and back wheels conjoined via left and right trolley plates and a handle bar. Front and back hand brake levers are mounted onto the handle bar. When front and back hand brake levers are squeezed by the rider, they create a constricting force which applies friction to the suspended cable via brake pads. This frictional force slows the rider's speed to his or her desired rate and brings the rider to a safe stop at a precise location along the suspended cable. The rider is able to quickly and easily remove the trolley from the suspended cable and transport it to another.

  • Patent number: 8807292
    Abstract: Improvements in a braking system for a zip line are presented. Braking occurs when a zip line rider makes contact with a braking carriage that slides along the zip line. The braking carriage pulls on a rope. The rope pulls on a length of chain in a chain reservoir to slide and lift the claim through the chain reservoir. The chain reservoir is an elongated tube that is mounted at an angle. As the zip liner moves further into the landing platform they lift a continuing greater amount of chain from the chain reservoir. The angle of the chain reservoir, coefficient of friction between the chain and the chain reservoir affects the pull-back. After the zip liner comes to a complete stop they remove the carriage from the zip line and gravity returns the brake mechanism. Minimum pull-back makes removal of the cable trolley easier.

  • 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.

  • Publication number: 20120291658
    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.

  • Publication number: 20120160122
    Abstract: A zip line trolley includes a frame assembled from a pair of spaced-apart parallel side plates and an inner beam, which is partially sandwiched between the side plates. The inner beam has a gallery of block-T-shaped cross section which extends its length. A shackle, from which a rider is suspended, can be pinned anywhere within the gallery. A main pulley, which is installed in an upper middle portion of the frame, rotates on a pair of sealed ball bearing races that are pressed on a hollow keyed shaft which slides into opposed grooves machined into each of the side plates. The keyed shaft is bolted between the side plates with a shoulder bolt passing transversely through both side plates. A water-wiping brake pad is pivotally mounted within the frame in front of the main pulley. A bumper is bolted between front portions of the side plates.
