ABSTRACT:
A preferred embodiment for a detechable gondola lift is disclosed in which carraiges on a closed circuit are detached from the circuit upon entering an end station and coupled to a semi-circular section before being recoupled onto the circuit upon exiting the end station. The semi-circular section has a drive wheel with a first drive mechanism on its periphery for driving the carriages over the semi-circular section. The first drive mechanism is located at regular intervals and driven at a predetermined first speed to impose a regular flow rate to the carriages leaving the semi-circular section and a regular distribution of carriages on the circuit. The semi-circular section also includes a second drive mechanism for imparting a slightly different speed to the carriages from that imposed by the drive wheel. One of the drive means has priority to impose a predetermined flow rate to the carriages leaving the semi-circular section. In another embodiment, the semi-circular section is divided into two straight rails and a circular rail on the drive wheel. In addition, the invention contemplates using two coaxial wheels: a drive wheel with pins and a support wheel. The pins may be fixed or retractable.
