Title: ELEVATOR SYSTEM
Abstract:
A roller guide shoe (40) for guiding an elevator car (2) includes pulleys (41, 42) that are provided with a non-oriented fiber layer (33) for low-noise, smooth operation. Damper units (4) can be used to reduce vertical vibrations of a stopped elevator car (2) of the elevator system (1). The damper unit (4) includes at least one roller (5, 6, 7) that is provided with a non-oriented fiber layer (33). In an active position, the roller (5, 6, 7) of the damper unit (4) is in contact with the guide rail (3). The damper unit (4) further includes a rotational damper (8, 9, 10) which is or can be connected to the roller (5, 6, 7) in order to dampen the rotational movements of the roller (5, 6, 7) during rotational vibrations of the stopped car (2).
