Abstract: 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.

Abstract: A lanyard for attaching a user's harness to a moveable member of a challenge course. The lanyard may comprise an upper section, a lower section, and a midsection arranged therebetween. The upper section may comprise an upper outer loop and an upper inner loop arranged within the upper outer loop, which form an opening configured to attach to the moveable member, and one or more structural connections. The lower section may comprise a lower outer loop and a plurality of lower inner loops configured to receive a coupling device for the harness. The plurality of lower inner loops may be sequentially arranged within the lower outer loop and attached to the lower outer loop via double shear connections.

Abstract: A carabiner gate for a carabiner having an outer cylinder and an inner cylinder, that can only be opened with the use of a properly located magnet to move a sliding pin and allow rotation of the outer cylinder to open the carabiner.

Abstract: An in-line brake having a displaceable carriage for slowing and stopping a zip track trolley, that allows the trolley to continue in its direction of travel after it stops. The carriage is then repositioned automatically to stop the next trolley.

Abstract: A system involving a machine designed to travel along a suspended track. An electronic safety system working in conjunction with mechanical components allows for multiple machines to operate simultaneously on the same track. A specific configuration of mechanical components provides for several capabilities, high speed turns, track switching, and the use of an external power source.
