ABSTRACT:
Chairlift or gondola lift with a carriage supporting a gondola or a chair and having a detachable grip for coupling on a continuously moving cable. In the terminals the carriage is uncoupled from the cable and it runs on a transfer rail. This transfer rail is equipped with friction drive wheels disposed along the carriage travel path for engaging the friction face of a running plate rigidly secured to the carriage so as to brake, accelerate or drive the carriage on the rail. During the night or bad weather periods a cover plate covers the friction face of the carriages disposed on the line and this cover plate is raised away in the terminals to clear the friction face. For removing the snow or ice which covers the friction face and hinders the correct friction drive of the carriage a brushing or rubbing device may be disposed along the carriage travel path so as to brush the friction face.
