The hydraulic truck crane is a specialized mobile crane that uses hydraulic power to lift and transport thousands of pounds. Hydraulics utilizes 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 vital in constructing major projects like bridges, airports, buildings and roads. A crane can complete in minutes jobs that will normally take hundreds of men and many hours to accomplish.
The great equipments are usually utilized in the construction of cities, houses, whole nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were likely constructed using basic cranes to enable the heaviest materials in one of the most awesome 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 mechanism which was utilized to collect water. The first official "cranes" appeared during Ancient Greece. These mechanism were used to create 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These cranes were originally made out of wood.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 need stronger and bigger equipments. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, in 1834. This machine could lift as much as 2 tons. That very same year, the addition of wire rope was added to the crane by Herr Albert Sr. who was an Official of the German Superior Board. The wire rope made the crane more durable and stronger. This addition allowed cranes to have a larger capacity for lifting 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 build cast iron cranes. The very first cast iron crane made by Germany was made in Neuburg.
