The chairs or the cabins of an overhead cable transport installation are driven on a transfer rail in a station by means of friction sheaves staggered along the travel circuit and interconnected by a belt drive arrangement. The rotational movement of the friction sheaves is derived from a cable support sheave by means of a movement take up module, having a girder like box secured adjacent to the girder which supports the friction sheaves. This module has a belt pulley interconnected to a belt pulley of the cable support sheave and a cog-wheel transmission between this belt pulley and the friction sheave,

Aerial cableway having a movement take up module

A single-cable aerial cableway including guide rails forming a lead-in guide, secured to a stationary cable support structure. The lead-in guide cooperates with a wheel secured to the grip so as to stabilize and position the grip and the load before they pass along the structure. The position of the lead-in guide is automatically adjusted when the position in height of the cable changes so that the weel always enter the lead-in guide.

Grip guiding device for aerial cableways

An overhead cable transport installation (e.g., a gondola lift or a chairlift) possesses a transfer rail in an end station on which grips of carriages are detached from the cable. At the exit of this transfer rail a coupling rail section extends parallel to the cable so that the cable is inserted between the jaws of the grip before the closing of the grip for clamping the cable. The coupling rail section comprises a safety device in the form of a sleeve partially surrounding the cable which allows the free passage of the grip when the cable is inserted between the jaws. Conversely, when the cable is outside the jaws, the grip is wedged and held back to prevent the chair from reaching the end of the transfer rail and falling down.
