Abstract (en)

[origin: WO2016096764A1] The invention relates to a damper unit (5) for an elevator for reducing vertical vibrations of an elevator cab of the elevator during a standstill comprising a stamp-like acting element (6), which acts on an end-face guide surface (11) of the guide rail (3). The acting element (6) is spaced apart from the guide rail (3) in an idle position and can be connected to the guide rail (3) without slip by means of an eccentric drive (14) in an active position. Force-transmitting elements containing a shock damper (9) for damping the motions of the elevator cab (2) during a standstill of the cab adjoin the acting element (6).
