The vast machinery are commonly used in the construction of cities, houses, whole nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed utilizing basic cranes to allow the heaviest materials in one of the most awesome construction projects ever.
The very first cranes were established during 3000 B.C. Egypt in King Ramses' reign. This lifting device was originally used to collect water. The very first official "cranes" appeared in Ancient Greece. These devices were utilized to create an entire nation throughout the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes started to change when dockyards started to require stronger and larger machinery. Hick & Rothwell developed the very first cast iron cranes during 1834, within Bolton, England. This machine was capable of lifting up to 2 tons. That same year, wire ropes were added to the crane by Herr Albert Sr. who was an Official of the German Superior Board. The wire rope made the crane stronger and more durable. This addition allowed cranes to have a bigger capacity to lift heavy weights.
The wire ropes were weaved together forming a more powerful rope with even more strength. The newly formed wire also added more flexibility. 4 years later, Germany began to make cast iron cranes. The very first cast iron crane made by Germany was made within Neuburg.
