The hydraulic truck crane is a specialized mobile crane which utilizes hydraulic power to lift and transport thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing in opposite directions on the boom's pistons so as to lift thousands of pounds. Hydraulic truck cranes are very important in constructing major projects like for example bridges, airports, roads and buildings. A crane could complete in minutes tasks which would normally take hundreds of men and lots of hours to accomplish.
These remarkable machinery have played a vital part in building cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably constructed with the help of basic cranes to allow the heaviest materials in one of the most awesome construction projects ever.
The very first cranes were established during 3000 B.C. Egypt during King Ramses' reign. This lifting device was initially used to collect water. The very first official "cranes" appeared during Ancient Greece. These devices were utilized to build a whole country during the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes began to change when dockyards began to need stronger and larger machines. Hick & Rothwell developed the very first cast iron cranes during the year 1834, in Bolton, England. This machinery 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 more durable and stronger. This addition enabled cranes to have a bigger capacity for lifting 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 started to make cast iron cranes 4 years later. The very first cast iron crane built by Germany was made in Neuburg.
