Hydraulic truck cranes are a particular type of mobile crane. These cranes utilize hydraulics and are able to lift thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing in opposite directions on the pistons of the boom in order to lift thousands of pounds. Hydraulic truck cranes are very vital in building major projects like bridges, airports, buildings and streets. A crane could accomplish in minutes tasks which would normally take hundreds of men and lots of hours to complete.
The great machinery are commonly utilized in the building of cities, homes, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were probably constructed using 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 during 3000 B.C. This was a portrayal of a lifting device that was utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These devices were utilized to build an entire country in the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes started to change when dockyards began to need stronger and bigger machinery. Hick & Rothwell designed the first cast iron cranes during 1834, in Bolton, England. 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 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 bigger capacity for lifting 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. Germany began to build cast iron cranes 4 years later. The first cast iron crane made by Germany was built in Neuburg.
