The hydraulic truck crane is a particular mobile crane which uses hydraulic power to lift and transport thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing on the pistons of the boom in opposite directions in order to lift thousands of pounds. Hydraulic truck cranes are really vital in constructing major projects such as bridges, airports, buildings and roadways. A crane can complete in minutes jobs which will normally take many hours and hundreds of men to accomplish.
These impressive equipments have played a very important part in constructing houses, cities, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably constructed with the help of basic cranes to allow the heaviest supplies in one of the most awesome construction projects of all time.
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 utilized to collect water. The very first official "cranes" appeared during Ancient Greece. These devices were utilized to build an entire country throughout the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes began to change when dockyards started to need stronger and bigger equipments. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, during the year 1834. This machinery can lift as much as 2 tons. That very 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 bigger capacity for lifting 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 benefit of flexibility. 4 years later, Germany began to build cast iron cranes. The very first cast iron crane made by Germany was made in Neuburg.
