1 1 how to do the elevator?

1 1 floor elevators are manufactured as follows:

1. Preparation materials: a big box, rope, pulley, board, battery, motor, switch, screw and screwdriver.

2. Put the big box on the ground as the elevator car.

3. Install pulleys on both sides of the bracket to ensure that they can rotate freely.

4. Pass the rope through the pulley, then fix one end at the top of the carriage and the other end at the bottom of the carriage.

5. Install wooden boards on one side of the bottom of the car as the floor of the elevator.

6. Fix the battery and motor on one side of the frame. Connect the switch to the motor.

7. Establish a mechanical connection between the motor shaft and the pulley. Fasten all parts together with screws and screwdrivers. Connect the switch to the battery.

8. Test whether the elevator can run normally, and ensure that the switch can control the motor to run and make the car lift. Elevator refers to the permanent transportation equipment serving several specific floors in a building, and its car runs on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than15.
