ELEVATOR DEVICE AND ROPE SHAKING SUPPRESS METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To suppress rope lateral shaking more efficiently.SOLUTION: An arithmetic control device 14 controls a drive device 11 according to detection signals output from rope lateral shaking sensors 12, 13. The arithmetic control device 14 further selectively outputs plural pieces of drive commands including first drive command and second drive command to the drive device 11. The first drive command is command for applying tensile force to a rope regardless of phase information of lateral shaking of the rope (main rope 6 or compensation rope 9). The second drive command is command for applying tensile force fluctuation to the rope for reducing lateral shaking based on the phase information of the lateral shaking.
