Objective:
To demonstrate how an escalator works mechanically using a manual crank system, without electricity or a motor – highlighting sustainability and energy conservation.
Model Design Overview:
This escalator works by manually turning a crank that rotates a roller, which moves a belt with cardboard steps attached, just like a real escalator – but powered by hand.
Video Step-by-Step Instructions:
Step 1: Build the Base
- Cut a rectangular base (approx. 40cm x 20cm).
- Cut two triangular or slanted side walls and fix them upright on the base.
- The slope should resemble a real escalator (around 45° angle).
Step 2: Create Rollers
- Use skewers or wooden sticks for top and bottom rollers.
- Insert them through straws fixed at both ends of the escalator walls.
- Make sure they can rotate freely.
Step 3: Attach the Belt
- Create a belt loop using a rubber band, long strip of paper, or thread.
- Attach small cardboard step pieces evenly spaced on the belt.
- Wrap the belt around the two rollers – steps should appear only on the upward-facing part.
Step 4: Add a Manual Crank
- On one side of the lower roller, attach a bottle cap or gear as a crank.
- When you rotate the crank manually, the belt with steps will move.
Step 5: Finishing Touch
- Cover side walls and base with color paper.
- Add tiny cutouts of people on steps.
- Optional: Add dummy LEDs for a tech look (no wiring).
How It Works:
- As you rotate the crank, it turns the roller.
- The step-attached belt moves up, mimicking escalator movement.
- Demonstrates manual motion mechanics and how escalators can work without electricity.
