The two treadwheels whose diameter is estimated to be 4 m or larger had been attached to every side of the axle and rotated together. Their capability was 2–3 tons, which apparently corresponded to the customary dimension of marine cargo.

Construction cranes later appeared in ancient Greece, where they have been powered by males or animals (such as donkeys), and used for the development of buildings.

The Romans adopted the Greek crane and developed it further. We are relatively nicely knowledgeable about their lifting strategies, thanks to rather prolonged accounts by the engineers Vitruvius (De Architectura 10.2, 1–10) and Heron of Alexandria (Mechanica 3.2–5).

Today, according to one survey, fifteen treadwheel harbor cranes from pre-industrial instances are nonetheless extant throughout Europe. Some harbour cranes have been specialised at mounting masts to newly-constructed sailing ships, such as in Gdańsk, Cologne and Bremen. Beside these stationary cranes, floating cranes, which could possibly be flexibly deployed in the entire port basin got here into use by the 14th century.
