Fairground roundabout with wagons moving on rails - has each cab rotating about vertical axis on chassis mounted on bogies

摘要

The fairground roundabout is movable and consists of wagons (4) hooked together and moving on a closed circuit of rails (1). Each wagon has a chassis (3), mounted on bogies (5) and supporting a cabin which rotated round a vertical axis (14) on the chassis. The wagons are moved by an electric motor joined to a tyre in contact with a track between the rails. The cabins rotate on a ring of balls between the chassis and the base of the cabin. They are rotated by a jack (17) fixed to the chassis and connected to a rack and pinion joined to the base of the cabin.
