Title:
ELEVATOR
Document Type and Number:
Japanese Patent JP2010208781
Kind Code:
A
Abstract:

To properly correct the floor landing position of a plurality of cars lifted by the same driving system.

When the car lands on a floor of an object story, the floor landing error detecting part 8a of the main control device 8 detects an error value of the floor landing position in a landing hall of the car 3 based on the input number of pulse signals from a floor landing sensor 7 of the car 3. A driving quantity calculating part 8b of the main control device 8 calculates the movement required distance of driving type deflector sheaves 5a and 5b for correcting the floor landing position of the car 3 so as to eliminate the error based on this detected error value. Deflector sheave driving devices 6a and 6b move the driving type deflector sheaves 5a and 5b in response to the distance calculated by the main control device 8, and corrects the floor landing position of the car 3 connected to the lower end of the main connecting rope 12 by upwardly correcting the height of the lower end of the main connecting rope 12 by curving the main connecting rope 12 of a winding destination.
