Hydraulic truck cranes are a particular kind of mobile crane. These cranes utilize hydraulics and could lift thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing in opposite directions on the boom's pistons in order to lift thousands of pounds. Hydraulic truck cranes are very vital in constructing major projects like airports, bridges, buildings and roadways. A crane could complete in minutes jobs which would normally take hundreds of men and lots of hours to complete.
These impressive equipments have played a vital part in building cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed utilizing basic cranes to enable the heaviest supplies in one of the most awesome construction projects ever.
The very first representation of a crane was featured during King Ramses' reign within Egypt during 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 used to create a whole nation throughout the 5th century B.C.
Initially, cranes were first made out of wood. It wasn't until the designers building dockyards decided they required something stronger and bigger did these machinery develop. Hick & Rothwell developed the first cast iron cranes within Bolton, England, in 1834. This machine can lift up to 2 tons. That very 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 stronger and more durable. 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. 4 years later, Germany began to make cast iron cranes. The first cast iron crane made by Germany was made within Neuburg.
