Safe shaft areas are thus such shaft areas in which the cabins 2, 2 'can be moved without initiating further safety measures such as emergency braking, ie engagement of the holding brake or engagement of a safety gear. For this purpose, at least one travel curve is stored in the safety program, according to which the cars 2, 2 'are accelerated, braked or held by the drives 6, 6' .
- the travel curve has three areas, an acceleration area, where the cars 2, 2 ' are accelerated with predetermined normal acceleration, a speed area where the cars 2, 2' are moved at a predetermined normal speed and a braking area, where the cars 2, 2 ' be decelerated with a given normal deceleration.

- the safety program advantageously determines a safe manhole area in real time for each car 2, 2 ' .
- those skilled in the art may use other definitions of a safety margin. So he can, for example, use a stronger delay than the normal delay, he can also emergency braking, ie initiate a collapse of the holding brake.
