The hydraulic truck crane is a particular mobile crane which uses hydraulic power to lift and move thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing in opposite directions on the pistons of the boom in order to lift thousands of pounds. Hydraulic truck cranes are really important in building major projects like airports, bridges, buildings and roadways. A crane could complete in minutes tasks that would normally take a lot of hours and hundreds of men to complete.
These impressive machinery have played a very important role in constructing cities, houses, individual buildings and entire nations throughout the ages. Even Egypt's Great Pyramids were probably built with the help of basic cranes to enable the heaviest supplies in one of the most amazing construction projects of all time.
The very first cranes were established in 3000 B.C. Egypt during the reign of King Ramses. This lifting mechanism was initially utilized to collect water. The first official "cranes" appeared in Ancient Greece. These devices were used to create a whole nation 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These cranes were originally made out of wood.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 require stronger and bigger machines. Hick & Rothwell designed the first cast iron cranes in the year 1834, within Bolton, England. This machine was capable of lifting up to 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 more durable and stronger. 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 benefit of flexibility. Germany began to build cast iron cranes 4 years later. The first cast iron crane made by Germany was made within Neuburg.
