Actuation of an intercepting apparatus

In the case of this lift installation (1), a car (3, 4) contains an intercepting apparatus (11), which is arranged on the car and is intended for braking and securing the car (3, 4) as required on the guide rail (9) or on a braking rail. The intercepting apparatus (11) is connected to an arrangement for actuating the intercepting apparatus (18), it also being possible for this arrangement to actuate the intercepting apparatus (11). The arrangement for actuating the intercepting apparatus (18) contains a driving body (20), which can be pressed, if required, against the lift shaft, preferably against the guide rail or braking rail (9), wherein the intercepting apparatus (11) is actuated by relative movement between the intercepting apparatus (11) and the driving body (20) pressed against the lift shaft. The driving body (20) contains, for this purpose, a curved driving surface (21), which is brought into engagement, if required, with the lift shaft or with the guide rail or braking rail (9).
