The hydraulic truck crane is a specific mobile crane that uses hydraulic power to raise and transport thousands of pounds. Hydraulics makes use of 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 very vital in constructing major projects like for example bridges, airports, buildings and roads. A crane could complete in minutes jobs which would normally take a lot of hours and hundreds of men to complete.
These impressive equipments have played a vital part in building cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were probably constructed utilizing basic cranes to enable the heaviest materials in one of the most remarkable construction projects ever.
The first cranes were established during 3000 B.C. Egypt in the reign of King Ramses. This lifting device was initially used to collect water. The very first official "cranes" appeared in Ancient Greece. These mechanism were used to create an entire nation during the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes began to change when dockyards began to need stronger and larger machines. Hick & Rothwell developed the very first cast iron cranes during the year 1834, in Bolton, England. 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 enabled cranes to have a bigger 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 started to make cast iron cranes 4 years later. The very first cast iron crane built by Germany was built within Neuburg.
