Swing bridge on boats

Swing bridge on boats

Inv. 401
Interpretation by Ermenegildo Menighetti, 1952 - 1953

In his presentation letter to Ludovico il Moro, Leonardo describes many revolving, joint and gantry bridges, often with a military purpose. These bridges are designed to be built with readily available and easily transportable materials. This bridge can be built using boats or barrels. It can be moved by a hoist operated on land and it can be placed in a niche created in the river embankment. The system is devised for rivers with calm waters.

The model is based on the drawing:
