Research on the Risk Points of Elevator Braking System

Elevator failures and accidents have always been a hot spot for urban residents and the media. Elevator accidents caused by brake failures are particularly serious. System evaluation of braking systems is the basis and prerequisite for scientific decision-making in urban management. This article analyzes and categorizes elevator braking accident cases, common problems in inspection and testing, common failures and problems found in safety assessment, and derives the risk distribution of elevator braking systems. The article pointed out that the failure causes of elevator braking system can be divided into braking system failure and braking system braking performance failure. A mathematical model of the elevator braking system health status was established, and the evaluation parameters of elevator braking system health characteristics were obtained.
