The hydraulic truck crane is a specific mobile crane that uses hydraulic power to lift and transport thousands of pounds. Hydraulics makes use of 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 really important in constructing major projects like for instance airports, bridges, roads and buildings. A crane can accomplish in minutes jobs which would normally take a lot of hours and hundreds of men to complete.
The vast equipments are commonly used in the building of cities, homes, whole nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely constructed using basic cranes to allow the heaviest supplies in one of the most amazing construction projects ever.
The very first representation of a crane was featured during the reign of King Ramses within Egypt during 3000 B.C. This was a portrayal of a lifting mechanism which was used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized to build an entire country 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 larger machines. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, during 1834. This machine was capable of lifting as much as 2 tons. That same year, the addition of wire rope was 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 to lift 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. 4 years later, Germany started to build cast iron cranes. The very first cast iron crane built by Germany was made in Neuburg.
