The hydraulic truck crane is a particular mobile crane which utilizes hydraulic power to lift and move 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 vital in constructing major projects like bridges, airports, roadways and buildings. A crane can complete in minutes tasks which would normally take hundreds of men and many hours to accomplish.
These impressive machinery have played a vital part in building houses, cities, entire nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were probably constructed using basic cranes to enable the heaviest supplies in one of the most awesome construction projects ever.
The first cranes were established during 3000 B.C. Egypt in the reign of King Ramses. This lifting mechanism was initially utilized to collect water. The very first official "cranes" appeared during Ancient Greece. These devices were utilized to build a whole nation during 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 evolve. Hick & Rothwell developed the first cast iron cranes during the year 1834, in Bolton, England. This machinery was capable of lifting as much as 2 tons. That very same year, wire ropes were 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 larger capacity for lifting heavy weights.
Eventually, 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. Germany began to make cast iron cranes 4 years later. The first cast iron crane made by Germany was built in Neuburg.
