The great machines are usually used in the construction of cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were probably constructed using basic cranes to enable the heaviest supplies in one of the most awesome construction projects ever.
The very first cranes were established in 3000 B.C. Egypt during King Ramses' reign. This lifting device was first used to collect water. The first official "cranes" appeared during Ancient Greece. These devices were used to create an entire nation during the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers building dockyards decided they needed something stronger and bigger did these equipments develop. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, during 1834. This machine was capable of lifting up to 2 tons. That very same year, wire ropes were added to the crane by an Official of the German Superior Board, Herr Albert Sr. The wire rope made the crane more durable and stronger. This addition allowed cranes to have a larger capacity to lift heavy weights.
Eventually, the wire ropes were weaved together to be able to form an even more powerful strength. This wire formation also brought the added benefit of flexibility. Germany started to build cast iron cranes 4 years later. The very first cast iron crane built by Germany was made in Neuburg.
