Parabolic swing bridge

Parabolic swing bridge

Inv. 400
Interpretation by Ermenegildo Menighetti, 1952 - 1953

This one span bridge has a parabolic profile and is secured to one of the two banks with a large vertical hinge. It is moved with ropes and hoists, aided by wheels or metal rollers that facilitate the sliding motion. It is also equipped with a counterweight tank, which balances the structure and helps manoeuvres when the bridge is suspended before being laid down on the opposite bank.

The model is based on the drawing:
