The hydraulic truck crane is a particular mobile crane that uses hydraulic power to raise and move thousands of pounds. Hydraulics uses 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 important in building major projects like for instance bridges, airports, buildings and roads. A crane could complete in minutes jobs which will normally take hundreds of men and lots of hours to accomplish.
The great equipments are commonly utilized in the construction of cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed using basic cranes to allow the heaviest materials in one of the most remarkable construction projects ever.
The very first cranes were established during 3000 B.C. Egypt in the reign of King Ramses. This lifting mechanism was first used to collect water. The first official "cranes" appeared in Ancient Greece. These devices were utilized to create a whole country in the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes started to change when dockyards started to need stronger and larger equipments. Hick & Rothwell designed the very first cast iron cranes during 1834, in Bolton, England. This machinery can lift up to 2 tons. That same year, the addition of wire rope was added to the crane by Herr Albert Sr. who was an Official of the German Superior Board. The wire rope made the crane more durable and stronger. This addition enabled 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 began to build cast iron cranes. The first cast iron crane made by Germany was built within Neuburg.
