An impact device (15) for an elevator installation (2) comprises an impact part (19) and a free-fall mass (27). In this context, the impact part (19) can be arranged on a rail (6) of the elevator installation (2) such that the impact part (19) is supported on a sliding bracket (8) attached to the rail (6). The free-fall mass (27) is guided so as to be able to move relative to the impact part (19). The guiding of the free-fall mass (27) is configured in this context such that the free-fall mass (27), initially raised to a determined free-fall height, transmits to the sliding bracket (8), at the end of its free-fall path and via the impact part (19) supported on the sliding bracket (8), an impulse which is dependent on the determined free-fall height. Further indicated is a method for post-adjusting rail securing devices (7) for an elevator installation (2). |
