Inv. 394
1952 - 1953

The model represents an automatic winch equipped with a system for raising columns, composed of two endless screws, along which a cart is inserted, moving on two bolts. The endless screws are connected to two toothed wheels that are connected, in turn, to a crank. The crank also actuates, by means of two ratchets, the forward movement of the cart on which the base of the column rests. In this manner, the advancement of the cart bearing the column is synchronized with the gradual raising of the column. Working from the basis of systems already drawn by Francesco di Giorgio Martini and other engineers, Leonardo drew this mobile winch for transporting and raising columns and obelisks

The model is based on the drawing:
