How Safe Are Residential Elevators?
Written by Jai Gaitonde
- Speed sensing device: This is arguably the most vital safety device as it would prevent the elevator from over-speeding while descending. This device is integral to preventing the cab from crashing to the floor of the elevator shaft in case of a failure of some sort. Now isn’t that reassuring?
- Safe doors: Elevators have doors that open to the doors of each floor in the building. A device in the home elevator prevents each of those doors from performing the opposite action at the same time. The device also prevents the elevator doors from closing when there is an object or person caught in between. Modern elevators have invisible rays of light that are sent back and forth from the elevator doors so that any object or person in between is detected and doors stop closing in. Sometimes, particularly in older elevators, there are safety edges that enable the doors to stop closing when coming into contact with a person or object.
- Interlocks are related devices that are situated in the hoistway. These prevent the elevator from moving from the landing when the doors are open.
- Emergency buttons are offered as well as alarms, phone and intercom buttons. Residential elevators also feature emergency lighting for use in the event of a power cut. Emergency power is provided to ensure the elevator doesn’t stall during power outage.
