PROBLEM TO BE SOLVED: To perform accurate floor aligning by locking one end part of a main cable in a main cable locking device capable of delivering/pulling-in the main cable and, if a difference occurs between a floor and a car floor, hoisting a car by delivering/pulling-in the main cable by the main cable locking device and then performing floor aligning. SOLUTION: A main cable locking device 51 locked in a hoistway 1 for locking one end part of a main cable 16 is constructed in such a manner that a screw bar is rotated forward/backward by a driving means so as to move a main cable locking plated threadedly engaged with this screw bar up and down and then the main cable end part is delivered/pulled in. The other end of this main cable 16 is fixed in a car 21, and by moving a guide plate 14 up and down via a hydraulic cylinder 12, a car 21 is hoisted. If a position difference between a floor 4 and a car floor exceeds a specified distance at this time, the driving means of the main cable locking device 51 is drive-controlled, the position difference is set within a specified distance by delivering or pulling in the end part of the main cable 16, and then the end part of the main cable 16 is returned to its middle location before the car lands at another target floor. |
