Embodiment Construction
[0042] The elevator installation 1 is formed from at least one elevator car 2 and an elevator drive 10 . Such as figure 1 The elevator installation 1 shown as an example additionally requires a carrier mechanism 11 and a counterweight 12, wherein the elevator drive 10 drives the carrier mechanism 11 and thereby drives the elevator car 2 and the counterweight 12 in opposite directions. to move. The elevator installation 1 requires at least one braking device 13 . The braking device 13 holds the stopped elevator car 2, for example during loading on the floor 6, or in an emergency situation the braking device 13 brakes the elevator car 2, for example, on an unexpected opening of a floor passage, Or for the elevator car 2 running too fast, for example, safety braking is performed when the bearing mechanism 11 fails. Different load situations require different braking or holding forces F B .
[0043] FIG. 2 shows a further braking device 13, which consists of a brake control u...
