Abstract: An elevator buffering device and an elevator system. The elevator buffering device includes a multi-stage buffer including: a body bracket; and a plurality of buffering elements mounted on the body bracket; wherein each of the buffering elements is at different heights when they are driven to operating positions in a vertical direction; a drive mechanism including: a power source for powering the drive mechanism; and a telescopic push rod pivotally connected to the body bracket; and a control element for controlling a telescopic length of the telescopic push rod of the drive mechanism so that one of the plurality of buffering elements on the body bracket is driven to the operating position.

Abstract: An elevator system and an elevator car. The elevator system includes one or more elevator cars traveling in an elevator hoistway along a guide rail, a shock absorbing device and a buffering device, the shock absorbing device is installed on at least one outside surface of the elevator car, and the buffering device is installed on an inside wall and/or a bottom of the elevator hoistway and configured to contact the shock absorbing device when the elevator car travels to lowest position along the guide rail.
