<p>An elevator utilizes actuators to eliminate the vibration of a lift car, operates a controller simply, utilizes fewer actuators to improve the vibration restraining effect, and enables the installation and adjustment to become easy. The present invention provides the elevator which comprises the lift car (1) lifting along guide rails (2), an acceleration sensor (20) for detecting the acceleration of the life car, and the actuators (21) driven in a manner of eliminating the vibration of the lift car (1) according to the signal detected by the acceleration sensor. In addition, the elevator also comprises guiding devices arranged at the lower and upper parts of the lift car. Guide roller are pressed to the guide rails by utilizing pressing springs (6, 8, 10, 12), and the rigidity of the guiding devices at at least one side of the upper and lower parts of the lift car is set to be 2-5 times of the rigidity of the guiding devices at the other side.</p> |
