The hydraulic truck crane is a particular mobile crane that utilizes hydraulic power to lift and transport thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing on the pistons of the boom in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are really vital in constructing major projects like for instance bridges, airports, buildings and roadways. A crane can accomplish in minutes tasks that would normally take hundreds of men and lots of hours to complete.
These impressive machinery have played a vital role in building cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely built utilizing basic cranes to enable the heaviest supplies in one of the most awesome construction projects of all time.
The first representation of a crane was featured during the reign of King Ramses 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 during Ancient Greece. These devices were used to build an entire nation in the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers building dockyards decided they needed something stronger and larger did these machinery evolve. Hick & Rothwell developed the very first cast iron cranes during the year 1834, in Bolton, England. This equipment was capable of lifting up to 2 tons. That very same year, the addition of wire rope was 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 enabled cranes to have a bigger 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. Germany began to build cast iron cranes 4 years later. The very first cast iron crane built by Germany was built within Neuburg.
