Analysis of Brake Material Issues in the Elevator Hoisting Accident

摘要

Brake is the frequent-use safety of elevator parts, also it is the important basis to maintain the safe operation of the elevator. In this paper, combined with an elevator hoisting accident, the elevator brake dismantling, internal structure type, the damage and the failure characteristics of the brake were analyzed. At the same time, the fault brake parts were analyzed in order from the aspects of material, and process of brake failure reasons were analyzed. Finally, the corresponding preventive measures were proposed according to the cause of the brake failure, avoiding similar accidents from happening again.
