- Prepare the Motor Housing: Attach the motor to the motor housing using the provided screws. Ensure the motor's terminals are accessible.
- Connect Wires: Connect the terminal clips to the motor's terminals. These clips will later connect to the battery compartment.
- Assemble the Pulley System: Mount the medium and large pulley wheels onto their respective spindles. Attach the motor pulley wheel to the motor shaft.
- Integrate Wheel Support: Secure the wheel support to the main cable car frame. This frame will hold the pulleys and the motor housing.
- Install Batteries: Open the battery compartment (battery cover) and insert 2 x 1.5V AAA batteries, observing the correct polarity. Close the battery cover securely.
- Attach Battery Compartment: Secure the battery compartment to the main frame. Connect the wires from the motor to the battery compartment terminals.
- Prepare the Tin Can: Ensure your chosen tin can is clean and dry. Apply the provided can sticker to decorate it, if desired.
- Attach Can Spindle: Insert the can spindle through the top of the tin can. This spindle will connect the can to the cable car mechanism.
- Secure the Tin Can: Attach the tin can, via its spindle, to the main cable car mechanism. Use the side wheel locks and swivel joint lock to secure it firmly.
- Install Cable Stop Valves: Place the cable stop valves at the ends of the cable car's upper structure. These help guide the string.
- Thread the String: Carefully thread the long string through the pulley system and the cable stop valves. Ensure it runs smoothly.
- Final Checks: Before operation, double-check all connections and ensure all screws are tightened. The cable car should move freely when pushed manually.
Operating Instructions
Once assembled, your Tin Can Cable Car is ready for operation.

- Set Up the Cable Line: Securely tie the ends of the long string to two fixed points. These points should be at a suitable distance and height to allow the cable car to travel freely. Ensure the string is taut.
- Position the Cable Car: Place the assembled cable car onto the taut string, ensuring the string is correctly seated in the pulley grooves.
- Activate the Motor: Locate the ON/OFF switch on the cable car's motor housing. Flip the switch to the 'ON' position. The motor will start, and the cable car will begin to move along the string.
- Observe Movement: Watch as the cable car travels back and forth, or up and down, depending on the incline of your string.
- Deactivate: To stop the cable car, flip the switch to the 'OFF' position.
Maintenance
To ensure the longevity and optimal performance of your Tin Can Cable Car, follow these simple maintenance guidelines:
- Cleaning: Wipe down the plastic components with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Battery Care: Remove batteries if the cable car will not be used for an extended period to prevent leakage.
- Storage: Store the kit in a cool, dry place away from direct sunlight and extreme temperatures.
- String Inspection: Periodically check the string for fraying or damage. Replace if necessary to ensure safe operation.
