First Construction Crane:
The first construction cranes known by the ancient Greeks were invented and the power of the cranes was provided by people, or at the four ends of the loader, such as donkeys.
Cranes were used to build high-rise buildings. Over time, larger cranes were built and developed.
Using a treadwheel (a large cylinder that went through the movement of workers inside it) and hiring more workers, heavier loads were available.
In the Middle Ages, cranes were introduced for loading and unloading ships and assisting in their construction. Some of the cranes were built for stability and stability above the stone towers. The first cranes were made of wood, but with The coming of the Industrial Revolution was replaced by wood, iron and steel.
