What is the maximum rated speed for Type C safeties?

The maximum rated speed for Type C safeties is 50 feet per minute (FPM). Type C safeties are designed for slower-speed elevators, typically found in applications such as low-rise buildings or service elevators. The specification of 50 FPM serves to ensure that these safeties will activate effectively in the event of an overspeed situation, allowing the elevator to stop safely and avoid accidents.

This maximum speed limit is established by industry standards to ensure that the safety systems can function properly under specified operational conditions. As elevators approach speeds above this limit, different types of safety devices may be required to accommodate the increased dynamics and forces involved.
