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 boom's pistons in order to lift thousands of pounds. Hydraulic truck cranes are really vital in building major projects such as bridges, airports, buildings and roadways. A crane can accomplish in minutes jobs that will normally take lots of hours and hundreds of men to accomplish.
The great machinery are commonly utilized in the construction of cities, houses, whole nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed with the help of basic cranes to enable the heaviest materials in one of the most amazing construction projects ever.
The very first representation of a crane was featured during the reign of King Ramses within Egypt in 3000 B.C. This was a portrayal of a lifting mechanism that was used to collect water. The first official "cranes" appeared during Ancient Greece. These mechanism were utilized to build a whole nation in the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they required something stronger and larger did these equipments evolve. Hick & Rothwell developed the first cast iron cranes within Bolton, England, during 1834. This machine 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 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 started to make cast iron cranes. The very first cast iron crane built by Germany was built within Neuburg.
