Hydraulic truck cranes are a specialized kind of mobile crane. These cranes use hydraulics and can lift thousands of pounds. Hydraulics makes use of 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 constructing major projects such as bridges, airports, buildings and roads. A crane could complete in minutes jobs which will normally take lots of hours and hundreds of men to complete.
These remarkable machines have played a very important role in constructing cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely built with the help of basic cranes to enable the heaviest materials in one of the most amazing construction projects ever.
The very first representation of a crane was featured during King Ramses' reign in Egypt in 3000 B.C. This was a portrayal of a lifting device that was used to collect water. The first official "cranes" appeared in Ancient Greece. These mechanism were utilized to create an entire nation during the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers building dockyards decided they required something stronger and larger did these equipments develop. Hick & Rothwell developed the very first cast iron cranes in Bolton, England, in 1834. This machinery could lift up to 2 tons. That same year, wire ropes were added to the crane by Herr Albert Sr. who was an Official of the German Superior Board. The wire rope made the crane more durable and stronger. This addition allowed cranes to have a bigger capacity for lifting heavy weights.
Ultimately, 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 began to make cast iron cranes 4 years later. The first cast iron crane made by Germany was made in Neuburg.
