ABSTRACT:
A system for the switching of guided vehicles vertically has a main guideway and a secondary guideway each having a pair of spaced guides. The guides of the main and secondary guideways branch at a switching region and diverge vertically. Each guide in the main guideway has a vertically disposed inwardly facing running surface extending upwardly from and outwardly of a horizontally disposed running surface. Each guide in the secondary guideway has a vertically disposed inwardly facing running surface, coextensive in the switching region with the vertical surfaces in the main guideway, extending downwardly from and inwardly of a horizontal running surface. The guided vehicle has a main support arrangement for coacting with or running on the horizontal surfaces of the main guides for supporting the vehicle and a guide apparatus for coacting with or running on the vertically disposed surfaces for providing lateral guidance. Also the guided vehicle has a retractable support arrangement for coacting with or running on the horizontal surfaces of the secondary guides when extended to support the vehicle from the secondary guides. When the retractable support arrangement is extended prior to a switching region the retractable support arrangement will coact with the horizontal surfaces of the secondary guides and conduct the vehicle away from the main guides. When the retractable support arrangement is not extended the vehicle will move along the main guideway through a switching region. The lateral guide apparatus is always able to coact with vertically disposed surfaces whether the vehicle is on the main or secondary guideway to provide at all times lateral guidance and braking or driving force as required.
