A transportation unit for a cable transportation system has a chair with a bench; a safety frame movable between an open position and a closed position and having a front bar; and at least one safety barrier, which is fixed to the front bar, extends predominantly between the front bar and the bench when the safety frame is in the closed position, and has a support with an anchoring portion fixed to the front bar, and a projecting portion, which projects from the anchoring portion, is elastically flexible under stress oriented in given or designated directions, and is substantially rigid under stress oriented in other directions.

A cable transportation system for transporting people or goods defines an advancing path extending between two end stations and having a designated length L, and has a hauling cable looped into a closed ring and having a forward branch and a return branch, which extend between the end stations; at least one vehicle configured to be alternately advanced between the two end stations, and selectively and alternately clamped to the forward branch and the return branch of the hauling cable at the end stations; and a drive member for advancing the hauling cable along the advancing path and selectively stopping the hauling cable when the vehicle clamped to the hauling cable is at one end station.

Device for coupling a vehicle to a traction cable, comprising a fastening configured to couple the vehicle to the traction cable, the fastening including at least two rotatable elements configured to occupy a coupling position in which said at least two rotatable elements are in contact with the traction cable and the vehicle is coupled to the traction cable, the device including a variable speed drive configured to modify a speed of rotation of said at least two rotatable elements when said at least two rotatable elements are in the coupling position, so that the vehicle moves relative to the traction cable.

Cableway installation, including at least one carrying cable supported by support blocks provided in the terminals, and actuating device for repositioning the carrying cable to periodically renew the surface directly in contact with the support blocks, wherein the actuating device is configured so as to make said carrying cable rotate on itself by angularly modifying the contact area according to the profile of the housing groove of the support blocks.

A portable line ascending device to enable users to ascend an incline on sliding or rolling sporting by travelling up an anchored line with the line ascending device. The device includes a mount, a plurality of sheaves connected to the mount, a motor driving the plurality of sheaves, and a power supply to supply electricity to the motor. The plurality of sheaves are configured to enable a line to be wound around at least a portion of each sheave of the plurality of sheaves and operable to engage the line to pull the line through the plurality of sheaves such that the line ascending device travels along the line.
