What is the function of an overspeed governor?

To increase car speed
To grip the rope and mechanically trip the car safety
To slow down the car's descent
To maintain a constant speed

The correct answer is: To grip the rope and mechanically trip the car safety

The function of an overspeed governor is to ensure safety in elevator systems by monitoring the speed of the car and responding appropriately if it exceeds safe limits. When the governor detects an excessive speed, it activates a mechanism that grips the hoisting rope, which initiates the tripping of the car’s safety system. This action helps to prevent potential failures that could lead to accidents, thereby protecting passengers and the elevator system itself. This mechanism is vital for elevator operation, especially in high-rise buildings where the consequences of overspeed could be severe. It is an essential safety feature that complements other safety devices within an elevator system, ensuring that the elevator operates within specified speed limits and enhancing overall passenger safety.
