The hydraulic truck crane is a particular mobile crane that uses hydraulic power to lift 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 building major projects like for example airports, bridges, roadways and buildings. A crane could accomplish in minutes tasks which would normally take many hours and hundreds of men to accomplish.
These impressive machines have played a very important role in building cities, houses, individual buildings and entire nations throughout the ages. Even the Great Pyramids within Egypt were probably built using basic cranes to enable the heaviest materials in one of the most amazing construction projects of all time.
The very first representation of a crane was featured during the reign of King Ramses within Egypt during 3000 B.C. This was a portrayal of a lifting device which was utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These devices were used to build a whole nation during 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 machinery evolve. Hick & Rothwell designed the very first cast iron cranes within Bolton, England, in 1834. This machinery was capable of lifting up to 2 tons. That 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 more durable and stronger. This addition allowed cranes to have a larger capacity for lifting heavy weights.
Ultimately, 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 began to make cast iron cranes 4 years later. The first cast iron crane made by Germany was built within Neuburg.
