Hydraulic truck cranes are a specific kind of mobile crane. These cranes use hydraulics and are able to lift thousands of pounds. Hydraulics uses forces being transmitted through oil pushing in opposite directions on the pistons of the boom so as to lift thousands of pounds. Hydraulic truck cranes are vital in constructing major projects such as bridges, airports, buildings and roadways. A crane could accomplish in minutes tasks which will normally take hundreds of men and a lot of hours to accomplish.
The great equipments are commonly used in the building of cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed using basic cranes to allow the heaviest supplies in one of the most remarkable construction projects of all time.
The first representation of a crane was featured during the reign of King Ramses in Egypt in 3000 B.C. This was a portrayal of a lifting device that was used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were used to create 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 began to require stronger and larger machinery. Hick & Rothwell designed the very first cast iron cranes during the year 1834, within Bolton, England. This machine was capable of lifting as much as 2 tons. That same year, wire ropes were added to the crane by Herr Albert Sr. who was an Official of the German Superior Board. The wire rope made the crane stronger and more durable. 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 began to make cast iron cranes 4 years later. The first cast iron crane built by Germany was made within Neuburg.
