The hydraulic truck crane is a specific mobile crane which uses hydraulic power to raise and move thousands of pounds. Hydraulics uses 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 essential in building major projects like bridges, airports, streets and buildings. A crane can accomplish in minutes jobs which will normally take a lot of hours and hundreds of men to complete.
The vast machinery are commonly utilized in the construction of cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably constructed with the help of basic cranes to enable the heaviest materials in one of the most remarkable construction projects of all time.
The first cranes were established during 3000 B.C. Egypt during the reign of King Ramses. This lifting mechanism was originally utilized to collect water. The first official "cranes" appeared during Ancient Greece. These devices were utilized to build a whole nation during the 5th century B.C.
Initially, cranes were first made out of wood. It wasn't until the designers building dockyards decided they needed something stronger and larger did these equipments develop. Hick & Rothwell developed the 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 stronger and more durable. This addition enabled cranes to have a larger 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. Germany started to build cast iron cranes 4 years later. The first cast iron crane built by Germany was made in Neuburg.
