A bogie configured to move along a track of an amusement ride includes two first lateral wheels, on each side of a vertical center plane of the bogie, for rolling along a run of the track. A second lateral wheel is mounted on each side of the vertical center plane and is movable perpendicular to the vertical center plane between a first position proximate the vertical plane and a second position spaced-away from the vertical plane. The bogie also includes a mechanism that provides a force to normally bias the second wheel toward the first position. The mechanism is configured such that the magnitude of the provided force increases with increasing separation between the second lateral wheel on one side of the vertical center plane and the second lateral wheel on the other side of the vertical center plane.

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.

For braking a zip line trolley, a wheel rides on the zip line cable. An array of toothed slots is disposed downslope from the wheel. A slope adjustment pin is fixed downward into a first toothed slot. At least one selection tab connects the slope adjustment pin to a rider. A brake pad is disposed downslope from the slope adjustment pin. The weight of the rider rotates the brake pad about the wheel to apply a braking force.

An indoor zip coaster has a zip coaster rail suspended above ground and forming a closed loop. At least one trolley located is on the rail, with a rider tethered to the trolley by a harness. The rail has plural sections, with each section of the rail including an incline portion and a decline portion. The trolley traverses the respective incline portion of one of the sections before traversing the respective decline portion of the one section. Each of the stations contains a respective incline portion of rail, a ramp for the rider to climb. The decline portion of rail of the next section extends from one station to the next station. By including stations with inclined portions of rail along the zip coaster path, a longer ride can be obtained. In addition, sensors and gates can be provided at the stations to allow a single rider on each rail section, with multiple riders on the overall zip coaster spread among the sections.

A trolley 100 for a rail 10 is described. The trolley 100 comprises a frame 110, a set S of wheels 120, including a first wheel 120A and a second wheel 120B, rotatably coupled to the frame 110 and an attachment member 130, coupled to the frame 110, for suspension of a load W therefrom, in use. The first wheel 120A is rotatable in a first plane P1 about a first axis A1 and the second wheel 120B is rotatable in a second plane P2 about a second axis A2. The first plane P1 and the second plane P2 define a line L. The trolley 100 is arrangeable in a first configuration, wherein the attachment member 130 is arranged at a first angular displacement D1 about the line L. The trolley 100 is arrangeable in a second configuration, wherein the attachment member 130 is arranged at a second angular displacement D2 about the line L, wherein the first angular displacement D1 and the second angular displacement D2 are different. A rail assembly 1, including the trolley 100 and the rail 10, is also described.

A safety check apparatus and method for testing a lanyard system prior to entering a challenge course. The apparatus comprises a track arranged at an entrance of the challenge course. The track includes a first position and a second position above a supporting surface. A moveable member is supported by and displaceable relative to the track. The track is connected to a course track that traverses the challenge course such that the moveable member is displaceable therebetween. A lanyard is attached to the moveable member and extends a length from the moveable member. A user harness is coupled to the lanyard. When at least a portion of a user's weight is supported by the harness, the connection point between the harness and the lanyard is positioned higher above the supporting surface at the second position of the track than at the first position of the track.
