Ancient Motors for Siege Towers

Conference paper
Part of the History of Mechanism and Machine Science book series (HMMS, volume 11)


In the paper are proposed some mechanical systems, all certainly used in the Classic Age, that could be easily adopted to power the siege towers, devices invented by Greek engineers and called Helepolis. These ancient motors are made up by capstans, tread wheels like those used for Greek-Roman cranes and counterweight motors, all installed into the helepolis. The proposed motors are also analyzed from a mechanical point of view in order to examine, at least theoretically, their effectiveness in such applications.
