Hydraulic truck cranes are a specific type of mobile crane. These cranes utilize hydraulics and are able to lift thousands of pounds. Hydraulics makes use of 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 building major projects like for instance airports, bridges, buildings and roadways. A crane can complete in minutes jobs which would normally take many hours and hundreds of men to accomplish.
The great equipments are commonly utilized in the construction of cities, homes, whole nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely built with the help of basic cranes to allow the heaviest materials in one of the most amazing construction projects of all time.
The first representation of a crane was featured during King Ramses' reign within Egypt in 3000 B.C. This was a portrayal of a lifting mechanism which was used to collect water. The very first official "cranes" appeared in Ancient Greece. These mechanism were used to build a whole nation during the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes started to change when dockyards began to require stronger and bigger machinery. Hick & Rothwell designed the first cast iron cranes in 1834, within Bolton, England. This machine can lift up to 2 tons. That 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 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. 4 years later, Germany began to make cast iron cranes. The first cast iron crane made by Germany was made within Neuburg.
