5 Everyday Dangers Not to Worry About
5. When the Elevator Stops at Your Floor, It Bounces Disturbingly—And Seems as If It’s About to Plummet
The elevator isn’t really bouncing; it’s adjusting to make sure its bottom is level with the floor outside. That way, you
won’t trip when getting off. The cables supporting an elevator are designed to stretch and contract with its load. So when
a car slows down at a floor, it relevels itself as people walk in and out. Besides, elevators never fall. If one safety feature
malfunctions, there is a host of software, mechanical, and electrical protection devices that prevent a catastrophe from happening.
