The hydraulic truck crane is a particular mobile crane which uses hydraulic power to lift and transport thousands of pounds. Hydraulics makes use of 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 essential in building major projects like for instance airports, bridges, buildings and streets. A crane can accomplish in minutes jobs which would normally take hundreds of men and lots of hours to complete.
These remarkable machines have played a vital part in building houses, cities, individual buildings and entire nations throughout the ages. Even the Great Pyramids within Egypt were probably constructed with the help of basic cranes to allow the heaviest materials in one of the most amazing construction projects ever.
The first representation of a crane was showcased during the reign of King Ramses in Egypt during 3000 B.C. This was a portrayal of a lifting device that was used to collect water. The very first official "cranes" appeared in Ancient Greece. These mechanism were utilized to create a whole country throughout the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes started to change when dockyards started to require stronger and bigger machines. Hick & Rothwell developed the very first cast iron cranes in 1834, in Bolton, England. This machinery 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 allowed cranes to have a larger capacity for lifting heavy weights.
Eventually, the wire ropes were weaved together to be able to form an even more powerful strength. This wire formation also brought the added benefit of flexibility. Germany began to make cast iron cranes 4 years later. The very first cast iron crane made by Germany was made within Neuburg.
