What is a "safety gear" in elevators?

A "safety gear" in elevators is a crucial safety device designed to bring the elevator car to a halt in the event of a free fall or excessive downward speed. This component activates when it detects that the elevator is moving faster than its permitted speed, effectively gripping the guide rails to stop the car safely and prevent potential accidents.

This functionality is vital for ensuring passenger safety, as it mitigates the risks associated with power failures or mechanical malfunctions that could lead to an uncontrolled descent. The safety gear is part of the overall safety systems mandated by codes and standards, which require elevators to have multiple fail-safes in place to protect users.

In contrast, devices to increase elevator speed, components for door operation, and signaling systems serve different purposes and do not directly contribute to stopping a free-falling elevator. Understanding the role of safety gear enhances knowledge of elevator safety mechanisms and their importance in design and operation.
