Hydraulic truck cranes are a specialized kind of mobile crane. These cranes utilize hydraulics and can lift thousands of pounds. Hydraulics makes use of 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 very important in constructing major projects such as airports, bridges, streets and buildings. A crane can complete in minutes jobs which will normally take hundreds of men and lots of hours to accomplish.
These remarkable machines have played a very important role in constructing cities, houses, entire nations and individual buildings 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 remarkable construction projects of all time.
The first cranes were established during 3000 B.C. Egypt in King Ramses' reign. This lifting device was initially used to collect water. The very first official "cranes" appeared during 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 needed something stronger and larger did these machines develop. Hick & Rothwell developed the very first cast iron cranes during the year 1834, in Bolton, England. This machinery could lift 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 more durable and stronger. This addition enabled cranes to have a bigger capacity to lift heavy weights.
Ultimately, 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 build cast iron cranes 4 years later. The very first cast iron crane made by Germany was built within Neuburg.
