PROBLEM TO BE SOLVED: To provide an elevator device capable of determining occurrence of abnormality of a hoisting machine with high reliability by simultaneously detecting noise and vibration of the hoisting machine. SOLUTION: In the rope type elevator device, a car 3 is lifted by driving the hoisting machine 1. The elevator device is provided with an elevator control board 8 for driving/controlling the hoisting machine 1; a noise sensor 6 for detecting noise level Dn of the hoisting machine 1; a vibration sensor 7 for detecting vibration level Dv of the hoisting machine 1; and a hoisting machine abnormality determination means 9 for inputting a failure signal E of the hoisting machine 1 to the elevator control panel 8 based on the noise level Dn and the vibration level Dv. The elevator control panel 8 has a monitoring informing unit 8a and drives the monitoring informing unit 8 in response to the failure signal E. COPYRIGHT: (C)2005,JPO&NCIPI
