METHOD FOR DETERMINING THE OPERATION AND CONDITION OF THE HOLDING BRAKE OF AN ELEVATOR AND HOLDING BRAKE

摘要

The invention relates to a method for determining the operation and/or condition of the holding brake (1) of a traction sheave elevator and to a holding brake (1). The holding brake (1) comprises a brake body (2); a brake pad (3); a brake shoe (4) with the brake pad (3) attached to it, said brake shoe being mounted on the brake body so that it can move between a braking position (I) and a released position (II); a spring (6) arranged to apply to the brake shoe a load tending to move it to the braking position (I); and an electromagnetic actuator (7) arranged to keep the brake shoe in the released position when activated. Using a displacement sensor (8), the displacement between the braking position (I) and the releasing position (II) is measured, and the operational state and/or condition of the brake is indicated by a monitoring device (9) on the basis of the measured displacement.
