Abstract (en)
[origin: WO2012163812A1] The invention relates to a method for controlling an elevator brake having a housing (4) and a brake unit (3), which is movable in the axial direction on a path between a braking position and a starting position and comprises at least one pulling unit (6), which brake unit (3) is moved at least by means of a first spring force (FBF) of at least one brake spring (BF). According to the invention, a lifting unit (5), which produces a lift (H, H1, H2), on the pulling unit (6) of the brake unit (3) produces a movement in the axial direction counter to the spring force (FBF) of the at least one brake spring (BF). By means of a second spring force (FAF) of an equalisation spring (AF) tensioned by the lift (H, H1, H2) of the lifting unit (5), the first spring force (FBF) of the at least one brake spring (BF) is reduced.
