...invent: A strong cable winch
You know it from the bicycle: when you put a small cogwheel on the front near the crank arm and a bigger one at the rear, you can climb a steeper mountain- but you climb more slowly using gears.
You can do the same with a winch and operate an electric cable car, cog railway, or something else...

 ...invent: From the electric car to a cable winch
|
 |
You can test the strength of the winch using this construction, by varying the number of metal objects being supported. |
 |
You can investigate what happens when you install different sizes of transmission wheels. Perform these types of tests yourself!

In this cog railway the upper cabin is pulled uphill by a cable which is lead through rollers while the other cabin goes downhill. The cable is powered and guided at the station at the top. The weight of the cabin that descends helps to pull the cabin going up. In the picture you see in the middle the place where the tracks separate to let the cabins pass each other. More about this at Lexi-TV. |
