The hydraulic truck crane is a specialized mobile crane that utilizes hydraulic power to raise and transport thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing in opposite directions on the boom's pistons in order to lift thousands of pounds. Hydraulic truck cranes are important in constructing major projects such as bridges, airports, buildings and roadways. A crane could accomplish in minutes jobs that will normally take hundreds of men and a lot of hours to complete.
The vast machinery are commonly utilized in the construction of cities, homes, whole nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were probably constructed using basic cranes to enable the heaviest materials in one of the most awesome construction projects of all time.
The very first representation of a crane was showcased during King Ramses' reign in Egypt during 3000 B.C. This was a portrayal of a lifting mechanism that was used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized to create an entire country throughout the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes started to change when dockyards started to need stronger and bigger equipments. Hick & Rothwell designed the very first cast iron cranes during the year 1834, within Bolton, England. This machinery could lift up to 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 allowed cranes to have a bigger capacity for lifting heavy weights.
Eventually, 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. Germany started to make cast iron cranes 4 years later. The very first cast iron crane built by Germany was made in Neuburg.
