There are plenty of ways to keep your building’s elevators safe, from elevator video monitoring to emergency brakes. However, one of the most important components for safe operation is the elevator overspeed governor. What exactly does this device do, and how can you maintain it?
This guide reveals everything you need to know about this vital safety feature.
Comparing Elevator Speed Control Mechanisms
If you ask an expert how elevators work safely, they’ll tell you that the overspeed governor is a crucial mechanism. It prevents the cab from traveling too fast, which could present safety issues for riders. There are two distinct styles: a centrifugal governor and an inertia governor.
The former relies on centrifugal force to slow the cab down. Flyweights will automatically shift outward once the elevator moves at a certain speed. As they change positions, the force will decrease and the system will come to a halt.
With an inertia-based overspeed governor, the same phenomenon occurs, though flyweights move due to inertia rather than centrifugal force.
How Overspeed Governors Protect Elevators and Their Passengers
Think about how dangerous a speeding car can be. If it were to crash, drivers, passengers, and even bystanders could become seriously injured, in addition to the damage the vehicle might sustain.
Although the transportation method is different, a speeding elevator can produce similar consequences. The elevator overspeed governor recognizes when the lift travels beyond its preset speed. Without this device, a free-falling lift could put all riders in danger.
Signs You May Have a Faulty Overspeed Governor
These devices are only triggered in emergency situations, but that doesn’t mean you should ignore them during standard operations. If you fail to notice certain warning signs, your governor could fail when you need it most. Keep an eye out for the following issues:
- Strange noises while the elevator moves
- Unsmooth stops
- Unreliable braking
It may be time to schedule a maintenance service if your system experiences any of these red flags.
Tips for Maintaining Elevator Safety Systems
Modern elevator safety features and governors can last for over a decade before they need to be replaced. To extend the lifespan of your system, invest in routine professional maintenance. Let a technician run through a detailed checklist to test elevator overspeed governor safety and function.
During a typical maintenance service, a technician will:
- Lubricate moving parts
- Inspect cables for damage
- Test pulley systems
- Calibrate governors
