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 in order to lift thousands of pounds. Hydraulic truck cranes are vital in constructing major projects such as bridges, airports, roads and buildings. A crane can accomplish in minutes jobs which would normally take hundreds of men and a lot of hours to accomplish.
These remarkable equipments have played a very important role in constructing houses, cities, individual buildings and entire nations throughout the ages. Even the Great Pyramids in Egypt were likely built with the help of basic cranes to allow the heaviest supplies in one of the most awesome construction projects ever.
The first cranes were established during 3000 B.C. Egypt in King Ramses' reign. This lifting device was initially utilized to collect water. The very first official "cranes" appeared during Ancient Greece. These devices were used to build an entire country in the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes began to change when dockyards started to require stronger and bigger machinery. Hick & Rothwell designed the very first cast iron cranes within Bolton, England, during the year 1834. 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 stronger and more durable. This addition enabled cranes to have a larger capacity for lifting heavy weights.
The wire ropes were weaved together forming a more powerful rope with even more strength. The newly formed wire also added more flexibility. Germany started to make cast iron cranes 4 years later. The first cast iron crane built by Germany was built in Neuburg.
