Embodiment Construction

[0059] FIG. 1 shows an example of an elevator installation 1 . The elevator installation 1 comprises an elevator car 2 connected via a support device 4 to a counterweight 3 . The elevator car 2 is driven via a support device 4 by a drive device 5 . Via guide shoes (or guide shoes) 23 , the elevator car 2 is guided substantially vertically in the elevator shaft 7 by the guide rails 6 . The elevator car 2 and the counterweight 3 move in opposite ways (or in opposite directions) within the elevator shaft 7 . The elevator car 2 is used to transport the load 10 to be transported. The elevator installation 1 is controlled by an elevator controller 8 . In the example shown, the elevator installation 1 is equipped with a braking device 11 which is able to hold the elevator car 2 stationary and, if required, to brake the elevator car 2 from a traveling state to a stationary state. For example, when an elevator car stops at a certain floor for the purpose of receiving or unloading a...

Abstract

In this lift installation, lift braking equipment (11) brakes and holds a lift cage (2). The lift braking equipment (13) consists of a number of brake units (12) which when required are brought into engagement with brake tracks (6), wherein the brake unit (12) for this purpose presses at least one brake plate (14) against the brake track (6) and produces a braking force (FB). According to the invention, for checking the braking equipment (11) an effective coefficient of friction ( [mu]e), which is generated during pressing of the brake plate (14) against the brake track (6), of the brake unit is ascertained. Moreover, a placing in operation with use of this checking method is illustrated and equipment for performing this placing in operation is presented.

Description

technical field [0001] The invention relates to a method of checking an elevator braking installation, a method of operating an elevator installation and a device for performing the operation according to the introduction of the independent patent claims. Background technique [0002] The elevator installation is inserted into the elevator shaft. It generally consists of an elevator car connected to a counterweight by means of support means. The elevator car is moved along a substantially vertical path of travel of the elevator car with drive means acting optionally on the support means, directly on the elevator car or directly on the counterweight. Such elevator installations have a mechanical braking system capable of holding the elevator car in a desired position, of braking the elevator installation or its moving mass during normal operation or of bringing the elevator car to a safe stop in the event of a malfunction down. For example, holding at a desired position is...
