The hydraulic truck crane is a specific mobile crane which utilizes hydraulic power to raise and transport thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing on the boom's pistons in opposite directions in order to lift thousands of pounds. Hydraulic truck cranes are really important in building major projects like for example bridges, airports, buildings and roads. A crane can accomplish in minutes tasks which would normally take many hours and hundreds of men to accomplish.
These remarkable machinery have played a vital part in constructing houses, cities, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely built using basic cranes to allow the heaviest supplies in one of the most amazing construction projects of all time.
The first representation of a crane was featured during King Ramses' reign within Egypt in 3000 B.C. This was a portrayal of a lifting device which was used to collect water. The first official "cranes" appeared in Ancient Greece. These mechanism were used to build a whole country during the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers building dockyards decided they needed something stronger and larger did these machinery evolve. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, in the year 1834. This machine was capable of lifting 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 bigger capacity to lift 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 make cast iron cranes. The very first cast iron crane built by Germany was built in Neuburg.
