Procedure for verifying a brake lift, a method of commissioning an elevator system and a device for performing a commissioning

摘要

Method for checking a brake system of elevator installation elevator brake (11) brakes and stops an elevator car (2) and installing elevator brake (11) is constituted by at least two brake units (12), which engage if necessary with vias brake (6), wherein the brake unit (12) presses for this purpose at least one brake plate (14) on the track brake (6) and generates a braking force (FB) and a coefficient of effective friction (μe) generated during the pressure of the brake plate (14) on the track brake (6) of the brake unit (12) is calculated wherein the coefficient of effective friction (μe) of the brake unit (12) is calculated by means of a measuring of the braking force (20) for measuring a braking force (FB) and through of a measuring normal force (21) for measuring a brake adjusting force (FNW ).
