<p>PURPOSE:To ease the extent of dimensional tolerance and assembly errors required for a member selecting tracks at each time of lifting and traversing of an elevator cage by installing plural units of cages shiftable along both lifting and traversing guide rails, and controlling each travel of these plural cages. CONSTITUTION:A cage 34 is travelable in both up and down directions in plural shafts of lifting passages 14 and also travelable between these lifting passages 14 via a traversing passage 16. In addition, a lifting guide rail 24 with a first groove part 26 installed along the lifting passage 14 and a traversing guide rail 28 with a second groove part 30 interconnected to the first groove part 26 both are installed there, and also there is provided a support means 44 which is made travelable along the first groove part 26 at time of lifting and also travelable along the second groove part 30 at time of traversing. Moreover, each movement of these plural cages 34 is controlled by a control means 50. With this constitution, dimensional tolerance and assembly errors required for a member for selecting tracks at each time of lifting and traversing of the cage 34 can be eased to some extent.</p> |
