Elevator Overloads Each elevator has a specific weight and passenger capacity that is posted in the elevator. If an elevator is overloaded it may well shut down between floors and trap you inside.

What happens if an elevator snaps?

Typically, safeties are activated by a mechanical speed governor. If one or more cables did snap, the elevator’s safeties would kick in. The governor is a pulley that rotates when the elevator moves. When the governor spins too fast, the centrifugal force activates the braking system.

How do elevators fail?

Elevators also have a safety brake that is attached to the underside of the car. Friction builds between the wedge and the rail, which brings the car to a stop at a comfortable rate. There is one more fail-safe. On the opposite end of the cables that attach to the elevator car, there is a set of counterweights.

Why do elevators fall up?

Regular elevator inspections are a crucial first step in maintaining the smooth, efficient function of your systems.

Why should I Have my elevator serviced regularly?
