A brake DZT - L

Brake is one of the frequently moving elevator safety components, it can make the elevator motor in the case of no power supply to stop rotation, and make the car effectively stop, whether the elevator can safely run is closely related to the working condition of the brake. A large number of accident cases, the elevator is one of the main causes of life or personal injury accident brake failure or own existence design flaws, resulting in the elevator have header, Dun bottom, slide, and even the phenomenon such as sheared. Therefore, strengthening the safety inspection of elevator brake is particularly important.

Elevator brake mechanical part of the common problems are as follows.

(1) stroke indicators collide with movable indicators, and designers of some manufacturers are not thoughtful about the uniqueness of the installation of stroke indicators.

(2) long-term use causes the brake shoe to fall off and glue (some brakes are glued rather than riveted).

(3) aging and cracking of the sealing rubber, falling into a foreign body causes the brake to get stuck.

(4) the electromagnetic iron core rusts, causing the brake jam.

(5) the design of the elevator iron core guiding mechanism is unreasonable, and the connection between the copper bar and the iron core breaks in many places, causing the brake to get stuck.

(6) elevator maintenance personnel on the brake inspection, maintenance methods improper.
