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.

In order to simplify the troubleshooting in a cableway during operation of the cableway, a unique car identification is assigned to each car, with the car identification of each car being known by the cableway control system. At least one function monitoring unit transmits malfunctions triggered by cars during the operation of the cableway to the cableway control system in a function status message FSi. The cableway control system assigns a malfunction that was received to the triggering car and the malfunctions together with the car identification of the triggering car are stored and evaluated in the cableway control system.

In order to be able to more reliably assess and react to the potential hazard when a vehicle of a cable car enters a station of the cable car, it is provided that the deflection of the vehicle before the station entrance is measured by the sensor and transmitted to the cable car control unit, that at the same time the occurrence of a wind gust before the station entrance is detected by the cable car control unit and that the cable car control unit controls a cable car drive as a function of the transmitted deflection and of the detected wind gust.

A device for locking a pivotal protective device, such as a safety bracket or a weather protection hood, of a chair for a chairlift. The device has interacting projections, one of which is connected to a frame of the chair and the other of which is connected to the protective device. At least one of the projections is resiliently mounted, and the projections are equipped with sliding surfaces which produce a deformation of the resilient bracket after a defined force has been applied to the safety bracket and allow the projections to slide past one another in both directions.

A device of a roller assembly or a trolley for a cable transportation system, the device comprising: a frame having two facing walls, which are provided with two respective first holes having a first axis in common; a pin that engages the first holes; a body mounted rotatably about the pin between the two facing walls of the frame, the body having a hole, which has a second axis and enables the passage of the pin; and an auxiliary constraining device that is selectively releasable configured to keep the axes of the first holes of the frame and of the hole of the body coincident even in the absence of the pin.

The invention relates to a tire conveyor for a transport device, in particular gondolas, of a cable car installation. The conveyor includes tires, which are arranged along a track, and a drive train for the tires. The drive train has at least one drive pulley, in particular a belt pulley, and at least one drive device, in particular a belt. A guide is arranged along the track, at least in some sections, and at least one measurement device for measuring at least one property of the drive train or a component of the drive train is displaceable on the guide.
