Pyramid Lifter

Size: 25 x 6 x 12 cm
Crank mechanism with cam control and levers

In Pharaoh's time: If the ancient Egyptians had used levers and cranes, that's a debatable point. In any case it would have been easier, as this model demonstrates.

An Egyptian worker lifts a pyramid with the help of a crank- and lever-mechanism.
The mechanism transforms the small stroke of an eccentric disc into the big stroke of the second lever. The trunk of the worker is an oscillating lever. His arms are the connecting linkage.
