Hydraulic truck cranes are a specific kind of mobile crane. These cranes make use of hydraulics and could lift thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing on the boom's pistons in opposite directions in order to lift thousands of pounds. Hydraulic truck cranes are very vital in building major projects like bridges, airports, buildings and roads. A crane can complete in minutes tasks which will normally take many hours and hundreds of men to complete.
The great machines are usually used in the construction of cities, homes, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed with the help of basic cranes to enable the heaviest materials in one of the most amazing construction projects ever.
The very first representation of a crane was showcased during King Ramses' reign within Egypt in 3000 B.C. This was a portrayal of a lifting device which was used to collect water. The first official "cranes" appeared during Ancient Greece. These mechanism were used to build an entire country in the 5th century B.C.
Initially, cranes were first made out of wood. It wasn't until the designers building dockyards decided they required something stronger and bigger did these machines evolve. Hick & Rothwell designed the first cast iron cranes within Bolton, England, in 1834. This machine was capable of lifting up to 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 allowed cranes to have a larger capacity to lift heavy weights.
Ultimately, the wire ropes were weaved together in order to form an even more powerful strength. This wire formation also brought the added advantage of flexibility. 4 years later, Germany started to make cast iron cranes. The very first cast iron crane made by Germany was made in Neuburg.
