Hydraulic truck cranes are a specific type of mobile crane. These cranes utilize hydraulics and could lift 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 vital in constructing major projects like bridges, airports, streets and buildings. A crane can accomplish in minutes jobs which would normally take hundreds of men and many hours to complete.
These remarkable machinery have played a very important part in constructing cities, houses, 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 amazing construction projects of all time.
The first representation of a crane was showcased during King Ramses' reign within Egypt in 3000 B.C. This was a portrayal of a lifting device that was utilized to collect water. The first official "cranes" appeared in Ancient Greece. These mechanism were used to build a whole country in the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes started to change when dockyards began to need stronger and larger machines. Hick & Rothwell developed the first cast iron cranes in the year 1834, within Bolton, England. 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 stronger and more durable. This addition allowed cranes to have a larger 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. Germany started to build cast iron cranes 4 years later. The first cast iron crane built by Germany was built within Neuburg.
