Abstract: A single pole aerial tramway apparatus carries multiple cycles in an upright position along the path of overhead cables from an aerial tramway. A single, bowed pole supports a multi-cycle support assembly on which multiple cycles are mounted. The bowed pole has a medial region that arcs distally from the cycles, so as to create additional space for loading and carrying the cycles. A bracket forms a junction point that detachably connects a pole cable end of the bowed pole to a cable extension member from the cable. The bracket may be hinged to enable the pole to sway to reduce mechanical stress. A multi-cycle support assembly attaches to the pole cycle end. A primary stabilization bar and a secondary stabilization bar carry and balance the multi-cycle support assembly. Cycle racks set on the stabilization bars receive the cycles in a front tire depression and a rear tire brace.

Abstract: Systems and methods for improved operations of ski lifts increase skier safety at on-boarding and off-boarding locations by providing an always-on, always-alert system that “watches” these locations, identifies developing problem situations, and initiates mitigation actions. One or more video cameras feed live video to a video processing module. The video processing module feeds resulting sequences of images to an artificial intelligence (AI) engine. The AI engine makes an inference regarding existence of a potential problem situation based on the sequence of images. This inference is fed to an inference processing module, which determines if the inference processing module should send an alert or interact with the lift motor controller to slow or stop the lift.

Abstract: A device for testing a cable deroped magnetic proximity detector positioned adjacent a cable sheave or sheave assembly on a cable operated ski lift. A sleeve of non-ferromagnetic material is temporarily secured coaxially over the steel lift cable and the sleeve is dimensioned in length and thickness in amounts sufficient to raise the cable simultaneously away from the detector and the adjacent sheaves whereby the detector indicates a derope condition. When the ski lift is operated to thereby move the sleeve over the detector and adjacent sheaves, a derope condition will be simulated and the alarm tested to determine whether it provides the appropriate signal.
