The hydraulic truck crane is a particular mobile crane that uses hydraulic power to raise and transport thousands of pounds. Hydraulics uses 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 vital in constructing major projects like bridges, airports, streets and buildings. A crane can accomplish in minutes tasks which would normally take hundreds of men and lots of hours to complete.
The great machines are commonly utilized in the building of cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed with the help of basic cranes to allow the heaviest materials in one of the most amazing construction projects ever.
The first representation of a crane was featured during King Ramses' reign in Egypt during 3000 B.C. This was a portrayal of a lifting mechanism which was utilized to collect water. The first official "cranes" appeared in Ancient Greece. These mechanism were used to create a whole country during the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes began to change when dockyards started to require stronger and bigger machinery. Hick & Rothwell designed the very first cast iron cranes during the year 1834, within Bolton, England. This equipment was capable of lifting up to 2 tons. That very 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 stronger and more durable. This addition enabled cranes to have a larger capacity to lift heavy weights.
Eventually, the wire ropes were weaved together in order to form an even more powerful strength. This wire formation also brought the added benefit of flexibility. Germany began to make cast iron cranes 4 years later. The first cast iron crane made by Germany was built within Neuburg.
