The hydraulic truck crane is a particular mobile crane that utilizes hydraulic power to lift and move thousands of pounds. Hydraulics uses forces being transmitted through oil pushing on the pistons of the boom in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are really important in building major projects like bridges, airports, buildings and streets. A crane can complete in minutes jobs which would normally take hundreds of men and many hours to accomplish.
These remarkable equipments have played a vital part in constructing cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably constructed using basic cranes to allow the heaviest supplies in one of the most remarkable construction projects of all time.
The first cranes were established during 3000 B.C. Egypt in the reign of King Ramses. This lifting mechanism was first used to collect water. The first official "cranes" appeared in Ancient Greece. These devices were utilized to build a whole nation in the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes began to change when dockyards started to require stronger and larger machines. Hick & Rothwell developed the first cast iron cranes in 1834, within Bolton, England. This machine was capable of lifting as much as 2 tons. That very 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 larger capacity to lift heavy weights.
Ultimately, the wire ropes were weaved together in order to form an even more powerful strength. This wire formation also brought the added benefit of flexibility. 4 years later, Germany began to build cast iron cranes. The very first cast iron crane made by Germany was made within Neuburg.
