Hydraulic truck cranes are a particular kind of mobile crane. These cranes make use of hydraulics and are able to 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 building major projects such as bridges, airports, roadways and buildings. A crane can complete in minutes jobs that would normally take many hours and hundreds of men to complete.
These remarkable machines have played a very important role in building houses, cities, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely built utilizing basic cranes to enable the heaviest supplies in one of the most awesome construction projects of all time.
The first cranes were established during 3000 B.C. Egypt in King Ramses' reign. This lifting mechanism was initially used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were used to build an entire country throughout the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes started to change when dockyards started to require stronger and larger machines. Hick & Rothwell developed the first cast iron cranes within Bolton, England, during the year 1834. This equipment was capable of lifting as much as 2 tons. That very same year, the addition of wire rope was 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 allowed cranes to have a larger capacity for lifting 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 benefit of flexibility. Germany started to make cast iron cranes 4 years later. The very first cast iron crane made by Germany was built in Neuburg.
