Hydraulic truck cranes are a specialized kind of mobile crane. These cranes use hydraulics and are able to lift thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing in opposite directions on the boom's pistons in order to lift thousands of pounds. Hydraulic truck cranes are essential in constructing major projects like bridges, airports, roadways and buildings. A crane could complete in minutes jobs which will normally take a lot of hours and hundreds of men to complete.
The great equipments are commonly utilized in the building of cities, homes, entire nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were probably constructed with the help of basic cranes to allow the heaviest materials in one of the most remarkable construction projects of all time.
The first cranes were established during 3000 B.C. Egypt in the reign of King Ramses. This lifting device was initially used to collect water. The first official "cranes" appeared in Ancient Greece. These mechanism were used to build an entire country during the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes started to change when dockyards began to require stronger and larger machinery. Hick & Rothwell designed the first cast iron cranes during the year 1834, within Bolton, England. This equipment was capable of lifting up to 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 stronger and more durable. This addition enabled cranes to have a larger capacity to lift 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 advantage of flexibility. 4 years later, Germany started to build cast iron cranes. The first cast iron crane made by Germany was made within Neuburg.
