Hydraulic truck cranes are a particular kind of mobile crane. These cranes use hydraulics and could lift thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing in opposite directions on the pistons of the boom in order to lift thousands of pounds. Hydraulic truck cranes are vital in constructing major projects such as bridges, airports, streets and buildings. A crane could accomplish in minutes tasks that would normally take hundreds of men and many hours to complete.
These remarkable machines have played a very important part in constructing cities, houses, individual buildings and entire nations throughout the ages. Even the Great Pyramids in Egypt were likely constructed using basic cranes to allow the heaviest materials in one of the most awesome construction projects ever.
The very first representation of a crane was featured during King Ramses' reign within Egypt in 3000 B.C. This was a portrayal of a lifting mechanism which was utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These mechanism were utilized to build a whole country 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 machinery evolve. Hick & Rothwell developed the very first cast iron cranes during the year 1834, in Bolton, England. This equipment was capable of lifting as much as 2 tons. That very 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 to lift 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. 4 years later, Germany began to make cast iron cranes. The very first cast iron crane built by Germany was built within Neuburg.
