Elevator Fail-Safes Need Regular Maintenance Too

Elevators are a safe and convenient way to get to any floor of your residential or office building. Each unit is outfitted with several fail-safe mechanisms that ensure the safety of passengers in case of an accident.

Elevators typically make use of several high-tension steel cables. In truth, each elevator only needs one cable to operate properly. However, several cables are used as a fail-safe to keep the elevator suspended in the event one cable snaps (this is very unlikely to happen if the unit is well-maintained).
