Abstract
The vibrations of an elevator are attenuated between the elevator and a cab by providing an elevator frame disposed in a first plane and a platform in a second plane, the platform being suspended from the frame by a plurality of side braces extending therefrom. A vibration attenuator is disposed directly between each side brace and the platform to attenuate vibrations that may pass between the frame and the platform.
