Hydraulic truck cranes are a specialized kind of mobile crane. These cranes utilize hydraulics and could lift thousands of pounds. Hydraulics utilizes 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 vital in building major projects like airports, bridges, buildings and roads. A crane could complete in minutes jobs that would normally take many hours and hundreds of men to complete.
The vast machines are commonly used in the construction of cities, houses, whole 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 supplies in one of the most awesome construction projects ever.
The very first cranes were established in 3000 B.C. Egypt in the reign of King Ramses. This lifting mechanism was first utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These devices were utilized to create an entire nation during the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes began to change when dockyards began to need stronger and larger equipments. Hick & Rothwell developed the first cast iron cranes in Bolton, England, in 1834. This equipment can lift 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 more durable and stronger. This addition allowed 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 very first cast iron crane made by Germany was built in Neuburg.
