⚡ Principle The motor rotates gears, which wind the cotton rope around the shaft, raising or lowering the lifting platform.
🔩 Parts
Wooden boards + motor base
Electrical machinery ×1
60mm iron shaft + large gear
Spiral gear ×1
Remote control (battery box) ×1
Screws ×4 + sleeves ×4 + cotton rope
📋 Steps
- Thread the cotton cord through a shaft sleeve and tie a knot. Pass the cord through the large gear and the small wooden board. Insert the iron shaft through the sleeves.
2. Assemble the lifting platform. Pass the other end of the cord through the hole on top, then through a shaft sleeve, and tie a knot to fix it.
3. Assemble the elevator pillars onto the base, then lock the platform between the left and right pillars.
4. Install the top plate. Fix the spiral gear on the motor. Use screws to fix the motor to the top plate and connect the remote control wires.
5. Install the step 1 components to the bottom of the top plate, adjust the position of the gears to just fit into the spiral gear.
6. Assembly complete! Load the remote control with two AA batteries. Press the button and see how the lift goes up and down.
⚡ Fun Fact! The first electric elevator was invented in 1880. Today, elevators move the equivalent of Earth's entire population every 72 hours!
💚 Tip Adjust gears at step 5 to mesh perfectly — otherwise the rope won't wind correctly.
