The hydraulic truck crane is a specific mobile crane which utilizes hydraulic power to lift and transport thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing on the boom's pistons in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are essential in constructing major projects like for instance airports, bridges, streets and buildings. A crane could complete in minutes tasks that would normally take lots of hours and hundreds of men to accomplish.
These remarkable machinery have played a very important role in building houses, cities, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely built with the help of basic cranes to allow the heaviest materials in one of the most amazing construction projects ever.
The first cranes were established during 3000 B.C. Egypt during the reign of King Ramses. This lifting device was initially used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were used 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 needed something stronger and larger did these machinery evolve. Hick & Rothwell developed the very first cast iron cranes during 1834, in Bolton, England. This equipment could lift up to 2 tons. That very same year, wire ropes were 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 enabled 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. Germany began to make cast iron cranes 4 years later. The first cast iron crane built by Germany was made in Neuburg.
