The hydraulic truck crane is a specific mobile crane that utilizes hydraulic power to raise and move thousands of pounds. Hydraulics uses forces being transmitted through oil pushing in opposite directions on the pistons of the boom in order to lift thousands of pounds. Hydraulic truck cranes are really vital in building major projects like for example bridges, airports, roadways and buildings. A crane can complete in minutes jobs that will normally take lots of hours and hundreds of men to accomplish.
These impressive machines have played a very important role in building houses, cities, entire nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were probably built with the help of basic cranes to allow the heaviest materials in one of the most remarkable construction projects ever.
The first representation of a crane was featured during the reign of King Ramses within Egypt during 3000 B.C. This was a portrayal of a lifting mechanism which was utilized to collect water. The first official "cranes" appeared during Ancient Greece. These devices were utilized to build an entire country 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These cranes were originally made out of wood.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 need stronger and larger equipments. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, during the year 1834. This machinery was capable of lifting as much as 2 tons. That same year, the addition of wire rope was 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 enabled 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 advantage of flexibility. Germany began to make cast iron cranes 4 years later. The first cast iron crane made by Germany was built in Neuburg.
