Hydraulic truck cranes are a particular kind of mobile crane. These cranes utilize hydraulics and are able to lift 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 essential in building major projects like for instance bridges, airports, roads and buildings. A crane could complete in minutes jobs that would normally take hundreds of men and many hours to accomplish.
These remarkable machines have played a vital part in constructing cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were probably built with the help of 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 the reign of King Ramses within Egypt in 3000 B.C. This was a portrayal of a lifting mechanism which was used to collect water. The very first official "cranes" appeared during Ancient Greece. These devices 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 develop. Hick & Rothwell developed the very first cast iron cranes in 1834, in Bolton, England. This equipment was capable of lifting up to 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 enabled cranes to have a bigger capacity to lift heavy weights.
Eventually, the wire ropes were weaved together to be able to form an even more powerful strength. This wire formation also brought the added advantage of flexibility. Germany began to make cast iron cranes 4 years later. The first cast iron crane made by Germany was built within Neuburg.
