Automatic Passenger Lift

An elevator or lift is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive ...a hydraulic machine by which automobiles are hoisted above the floor to give access to the underparts.A passenger elevator is any elevator intended for the transport of people through a building. These elevators can vary drastically in terms of size, speed and interior options depending on the use of the elevator.Sometimes called vertical platform lifts, are best suited to smaller passenger numbers (up to 5 people) travelling shorter distances. These access lifts can range in size from one person/wheelchair user to up to five people.A motor at the top of the shaft turns a sheave—essentially a pulley—that raises and lowers cables attached to the cab and a counterweight. Gears connect the motor and sheave in slower systems. Faster elevators are gearless; the sheave is coupled directly.
