Beskrivning
Leonardo Da Vinci "Leverage Crane", byggsats SNAP-KIT, behövs ej målas eller limmas.
The leverage crane is developed from Leonardo's sketchbook concepts, in this case for a heavy-lift crane system that uses a ratcheting system to rotate in only one direction while providing leverage to raise the load with a fraction of the force needed with a simple pulley.
