Escalators
An escalator is an electrically powered staircase, the steps of which are placed on a continuously rotating mechanism. They serve to carry people up or down. They can carry more people than elevators. The heart of an escalator is a pair of chains wrapped around two pairs of gears. The electric motor turns the upper gear, which turns the sleeve gear. A typical escalator uses a 100 horsepower motor to turn the gears. The motor and chain system are housed inside a truss, a metal structure that runs between the two floors. Instead of moving a flat surface on a belt, the chain system moves a series of steps. The most important detail about escalators is the way these steps move. The steps are always on the same level as the chain moves. At the top and bottom of the escalator, the steps fold over each other to create a flat platform. This makes it easier to get up and down the escalator. Each step on the escalator has two sets of wheels that rotate along two separate paths.
The upper assembly is connected to a rotating chain and is therefore pulled by a gear at the top of the escalator. The other set of wheels simply slides along their tracks, following the first set. Escalator systems are not as good at lifting dozens of floors as elevators, but they are much better at transporting people short distances. This is due to the high loading speed of escalators. When the elevator is full, you must wait for it to reach the floor and come back before others can enter.
