Swivel Crane

The Rotating Crane is a wooden mechanical puzzle to build from the Leonardo's Ideas collection, a series inspired by the visionary inventions of Leonardo da Vinci . This model pays homage to one of his most ingenious creations, the rotating crane designed for the construction of the dome of Santa Maria del Fiore in Florence , an architectural masterpiece conceived by Filippo Brunelleschi .

When ideas are guided by science, they impress with their rationality and precision. When they are driven by creative genius, they transcend centuries. The Gru Girevole perfectly illustrates this convergence of engineering, intuition, and innovation. By assembling this model, the player rediscovers a machine essential to one of the greatest construction projects of the Renaissance.

In 1436 , the Florence dome was not yet topped with its lantern. The crane designed by Leonardo da Vinci then made it possible to position the last blocks of marble with remarkable precision. Equipped with a 360° rotating arm and a screw system allowing the lateral movement of the load , the crane operated by pushing, demonstrating a surprisingly modern level of mechanical expertise.

The model is composed of various precisely cut birch plywood components . Each construction step invites observation, understanding, and assembly of the mechanisms that made this technical feat possible. The assembly becomes a true immersion in the history of engineering, combining reflection, patience, and the pleasure of building.

Produced in a limited edition to celebrate the 600th anniversary of Brunelleschi's dome , each crane is numbered with a year between 1420 and 2020 , making this model a true collector's item . Once assembled, the Rotating Crane becomes an impressive decorative object, at once elegant, historical, and educational.

At the crossroads of construction game , mechanical puzzle and heritage object , the Gru Girevole is an exceptional gift idea for lovers of history, engineering and wooden creations inspired by the genius of the Renaissance.
