摘要 <p>An elevator system includes a car assembly, a drive assembly, and a vibration-damping device (16) arranged at a connection between the top of the car assembly and the drive assembly. The vibration -damping device (16), which includes springs (32,34,36) that have varying spring stiffnesses and varying heights, is configured to provide a total spring stiffness between the top of the car assembly and the drive assembly. The total spring stiffness varies as a function of a mass of the car assembly.</p>
