Hydraulic truck cranes are a particular kind of mobile crane. These cranes use hydraulics and could lift thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing on the pistons of the boom in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are important in constructing major projects like for instance airports, bridges, buildings and roadways. A crane could accomplish in minutes jobs which would normally take hundreds of men and many hours to complete.
The vast machinery are usually utilized in the building 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 awesome construction projects of all time.
The very first representation of a crane was featured during the reign of King Ramses 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 create an entire country during 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 machinery evolve. Hick & Rothwell designed the very first cast iron cranes in Bolton, England, in 1834. This equipment was capable of lifting up to 2 tons. That very 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 more durable and stronger. This addition enabled cranes to have a bigger 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. Germany started to build cast iron cranes 4 years later. The very first cast iron crane built by Germany was made in Neuburg.
