Per code, what is the maximum speed at which the safety mechanism must be set when activated by a governor?

The maximum speed at which the safety mechanism must be set when activated by a governor is properly set at 75 feet per minute (fpm). This figure is based on safety regulations outlined in elevator codes, which ensure that elevators have adequate protective measures in place to prevent accidents during unexpected conditions, such as over-speed situations.

The governor is a critical safety device in elevators, as it is responsible for monitoring the speed of the elevator car. If the car exceeds the set speed, the governor activates the safety mechanism to engage the elevator's braking system, thereby halting the car's movement. The stipulation of 75 fpm serves as a threshold to balance safety and operational effectiveness, ensuring that the elevator can safely stop without risking failure of the system components.

Understanding this set limit is essential for elevator technicians and engineers, as compliance with these standards is crucial for maintaining safe elevator operations in commercial and residential buildings.
