摘要:
Elevator safety brake and/or safety actuator health monitoring systems and methods including an elevator car moveable within an elevator shaft along a guide rail, and a first safety brake assembly arranged on the elevator car and configured to engage with the guide rail to provide emergency braking to the elevator car. The first brake assembly includes a first safety brake and an electronic safety actuator operably connected to the first safety brake. A health monitoring element is in communication with the electronic safety actuator. The health monitoring element is configured to record information associated with operation of the first safety brake assembly, compare the recorded information against at least one predetermined threshold, and when the recorded information exceeds the at least one predetermined threshold, generate a notification that maintenance is required.
