Chairlift or gondola lift with a carriage supporting a gondola or a chair, the carriage including a detachable grip for coupling on a continuously moving cable. In the terminal, the carriage is uncoupled from the cable and it runs on a transfer rail. This transfer rail is equipped with friction drive sheaves for engaging a friction plate rigidly secured to the carriage. The sheaves are driven at a different speed with respect to the direct neighboring sheave so as to decelerate or to accelerate the carriage. The friction plate has a high friction coupling zone and a low friction coupling zone which permits a slip engagement with the friction sheave. The high friction coupling zone of the plate is shorter than the distance betwen two successive sheaves.

Chairlift or gondola-lift having a friction-based driving device for

In the by-pass zone of a car transfer track, in a terminal station of a detachable gondola lift or chairlift, the cars are driven by tired wheels. Transmission between two successive wheels comprises two toothed bevel pinions, wedged onto the wheel spindles, which engage with an inverter bevel pinion inserted between adjacent toothed benel pinions.
