Treadmill Crane is a technology in Age of Empires II that can be researched at the University. Once researched, the construction speed for all buildings is increased by +20%. Treadmill Crane helps players to establish forward bases more quickly or build structures close to enemy territory, especially Castles or Town Centers, which can otherwise take a while to complete.

Despite not having access to Treadmill Crane, the Spanish have the fastest builders in the game due to their civilization bonus that gives them +30% working speed. However, they do not benefit from their bonus in Wonder Race games because Wonders are built at a fixed time for all civilizations.

Trivia[edit | edit source]

  • The treadmill crane depicted in-game is also a counterweight crane. It uses the same counterweight model from the Trebuchet albeit smaller.
  • The Western European, Central European, Mediterranean, and East Asian Lumber Camps have a Treadmill Crane. The Eastern European and Native American ones also have one but without the treadmill. However, a European style treadmill crane would have been unknown to the Mesoamericans and East Asians in reality.
  • Serjeants are not affected by Treadmill Crane.

History[edit | edit source]

The construction of castles, cathedrals, and other major building projects required the invention of new techniques, as well as the re-discovery of ancient technologies. A critical tool known to the ancients but lost to the Europeans of the Dark Ages was the crane. The simple crane was a long pole with block and tackle gear that was used to pull loads to a height. The treadmill crane was an improvement over the simple version. It used a large circular treadmill upon which men walked. Gears converted the horizontal circular motion into vertical turning, providing power to wind ropes around a drum and pull up heavy loads. A variation of the treadmill crane employed a capstan that men could push against, like those used on sailing ships to raise anchors.
