A stop for stopping a trolley on a rail is described. The trolley comprises a set of wheels, including a first wheel and the rail provides, at least in part, a running surface, including a first portion and a second portion thereof, for the first wheel. The stop comprises an actuator providing a third portion of the running surface between the first portion and the second portion and an arm, coupled to the actuator. The stop is arrangeable in a first configuration, wherein the arm is arranged to block the trolley therepast. The stop is arrangeable in a second configuration, wherein the arm is arranged to allow the trolley therepast. The stop is arranged to move from the first configuration to the second configuration by actuation of the actuator, preferably by a movement of the actuator in a direction transverse to the third portion of the running surface.

A line bypass system includes a support structure including a first support portion and a second support portion spaced apart from the first support portion. The support structure includes an attachment portion that attaches the first support portion to the second support portion. The first support portion and the second support portion define a first opening on a first side of the attachment portion and a second opening on a second side of the attachment portion. The first opening movably receives a first guide wire and the second opening movably receives a second guide wire.

For zipline spring segment, the spring segment includes two spring sub-segments, an end cap, and a guide. The two spring sub-segments each include a set of spring coils, each spring coil set including a large diameter end and a small diameter end, wherein each of the spring coils of the spring segment nests completely within a neighboring spring coil and a cable passes through the spring coils. The end cap is disposed on the large diameter end of the spring coils, the end cap including a hole that receives the cable. The guide connects the two sets of spring coils of the spring sub-segments at the small diameter ends. The guide guides the cable through a center of the spring segment, wherein the guide and the end caps are configured to be in contact upon a full compression of the spring coil segment.

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.
