Automatic Passenger Elevator

Automatic elevator means a passenger or freight lift operated by push buttons so that the starting, moving, leveling, holding and opening and closing of the doors is entirely automatic.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.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.
