The invention relates to an elevator (1), comprising a first and a second cab (2, 3) that can be moved along a common track. In addition, the elevator (1) comprises a safety device (22, 23) by means of which the two cabs (2, 3) can be monitored and a shaft information system, which is connected to the safety device (22, 32) and by means of which the speed and the position of the two cabs (2, 3) can be determined. If the two cabs (2, 3) fall below a safety distance (D, D'), a first braking action can be taken for at least one first cab (2, 3) by means of the safety device (22, 32). The elevator (1) is characterized in that a deceleration curve (b, b') can be specified for the at least one first cab (3) by means of the safety device (22, 32) when the first braking action is taken. A second braking action can be taken for the at least one first cab (3) by means of the safety device (22, 32) if the deceleration curve (b, b') is exceeded. |
