Hydraulic truck cranes are a specific type of mobile crane. These cranes make use of hydraulics and could lift thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing on the boom's pistons in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are very vital in constructing major projects like bridges, airports, buildings and roads. A crane can accomplish in minutes tasks which would normally take hundreds of men and lots of hours to complete.
These remarkable machinery have played a very important role in building cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely constructed utilizing basic cranes to allow the heaviest materials in one of the most awesome construction projects of all time.
The first representation of a crane was featured 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 mechanism were utilized to create a whole country during the 5th century B.C.
Initially, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they required something stronger and bigger did these equipments evolve. Hick & Rothwell designed the very first cast iron cranes in Bolton, England, in 1834. This machine was capable of lifting as much as 2 tons. That 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 bigger capacity to lift heavy weights.
The wire ropes were weaved together forming a more powerful rope with even more strength. The newly formed wire also added more flexibility. 4 years later, Germany started to build cast iron cranes. The very first cast iron crane built by Germany was built within Neuburg.
