Patent attributes
For A zip line trolley brake system includes a cable suspended between upper and lower support platforms which, together, function with rider harnessing, loading, and take-off with a passive braking trolley allowing a controlled descent and barrel spring system providing addition braking near the end of a cable termination. The zip line trolley positioned atop a cable includes a frame assembled from a pair of parallel side plates, a four-sided rotational brake pad, and a parabolic groove wheel which is sandwiched between side plates, and a lever. A lever from which a rider is suspended, can be pinned anywhere within the trolley's circular toothed slot instilling a brake force for the cable slope. A trolley brake generally square sides are grooved for cables and fabricated from a durable polymeric material is rotatably within affixed side plates. A spring system includes a football-shape springs, spring spacers, bump spring spacer receiver, and a locking inserts designed to fasten the springs and allow the springs to collapse within themselves reducing the compression length. A bump spring spacer receiver makes contact with the zipline trolley further decelerating the suspended rider as contact is made with the springs.
