Ups and Downs - The Truth about Elevators

Tags: Elevators, How elevators Work, Elevator Problems, Elevator Solututions
For most of us an elevator is an awesome little device which we use every day. However, there is a lot more going on in that contraption than you might think. Here are some quick facts about the elevator.
| | Elevators are supported by multiple steel cables. Each cable alone can support a fully loaded car. |
| | The only elevator fall due to a complete cable system failure was when the cables were severed by an airplane crashing into the Empire State Building in the 1940's. |
| | An overloaded elevator will usually not move. The doors will stay open and a buzzer may ring until enough people get off the elevator to reduce the weight. |
| | Some people believe they have been in an elevator where the elevator car fell several floors and then "caught itself". This feeling is a mystery. Elevator experts believe people may think this happened because they 1) got on an elevator going in a different direction than expected, or 2) saw the elevator floor indicator lights flash by quickly which gave the visual impression of falling. |
| | If the car is not at the landing, the hall doors can't open because their opening can only be triggered by the arriving car engaging an unlocking device after the elevator has stopped at the landing. |
| | Leaving the car on your own could result in injury. Elevator cars are designed as "safe rooms". The safest place is inside the car. Ring the alarm and wait for help. Leave the car only with the assistance of professional rescuers. |
| | The call is registered just once; movement is in response to the elevator controllers. |
