The hydraulic truck crane is a specific mobile crane that uses hydraulic power to raise and move thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing in opposite directions on the pistons of the boom so as to lift thousands of pounds. Hydraulic truck cranes are very important in constructing major projects like for example bridges, airports, streets and buildings. A crane could complete in minutes jobs that would normally take hundreds of men and a lot of hours to complete.
The great machinery are usually used in the building of cities, homes, whole nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably constructed using basic cranes to allow the heaviest materials in one of the most remarkable construction projects of all time.
The very first cranes were established in 3000 B.C. Egypt in the reign of King Ramses. This lifting mechanism was initially used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were used to create an entire country during the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes began to change when dockyards began to require stronger and bigger equipments. Hick & Rothwell developed the first cast iron cranes in the year 1834, within Bolton, England. This machine was capable of lifting as much as 2 tons. That same year, wire ropes were 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 allowed cranes to have a larger capacity to lift heavy weights.
Eventually, 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. Germany started to make cast iron cranes 4 years later. The first cast iron crane made by Germany was made in Neuburg.
