Elevators of
Lifts as they are popularly known are used to transport people up and down
in tall buildings. The lift cage or elevator car is lifted up and down by a spool that is turned by an electric motor. The elevator car is attached to the spindle by a strong steel cable. Tracks attached to the sides of the elevator shaft ensure that the elevator car moves in a straight line. A counter weight balances the weight of the elevator car so that it becomes easy to pull it up. To move the elevator car up the motor rotates in a direction so that the cable gets wound around the spindle. To move the elevator down, the motor moves in such a direction that the cable gets unwound. Let us now try to make our own model elevator.
