Invention of Cranes

Greek Cranes
  • Lets pay homage to the Greeks for their devotion
    and the Romans for their versatile perspectives
    behind inventing cranes.
  • According to a journal article published in The
    Journal of Hellenic Studies, archeologists
    predict the construction of Greek sculptures in
    6th Century B.C. 
  • They noticed some grooves and holes in some of
    stone structures that seemed to be created by
    some kind of lifting device. These lifting
    devices are termed as cranes.

Ancient Greek Crane Model
  • It was a simple winch and pulley hoist machine
    that replaced ramps as the main means of vertical
    motion in 6th Century B.C

Roman Cranes
  • Impressed with the Greek talent, Romans adopted
    their crane technology and developed it further. 
  • Two Roman engineers, Vitruvius and Heron of
    Alexandria in their respective studies (De
    Architectura 10.2, 110) and (Mechanica3.25)
    reveal how Romans used Greco-Roman cranes for
    lifting techniques.
  • These cranes were known as Trispastos (Three-pulle
    y crane) and Pentaspastos (Five-pulley crane).
    Pentaspastos was used to lift the capital blocks
    of Trajans Column weighing 53.3 tons to a height
    of about 34m.

    from ancient periods until the industrial
    revolution.
