Hydraulic truck cranes are a specialized kind of mobile crane. These cranes utilize hydraulics and could lift thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing on the boom's pistons in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are important in building major projects like for example bridges, airports, buildings and roadways. A crane could complete in minutes tasks which would normally take lots of hours and hundreds of men to accomplish.
These impressive machines have played a vital part in building houses, cities, individual buildings and entire nations throughout the ages. Even the Great Pyramids in Egypt were probably built utilizing basic cranes to allow the heaviest materials in one of the most remarkable construction projects ever.
The first representation of a crane was showcased during King Ramses' reign within Egypt during 3000 B.C. This was a portrayal of a lifting device that was utilized to collect water. The first official "cranes" appeared in Ancient Greece. These mechanism were used to create an entire country throughout 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 equipments evolve. Hick & Rothwell designed the very first cast iron cranes during 1834, in Bolton, England. This machinery can lift 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 bigger capacity to lift 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 advantage of flexibility. 4 years later, Germany began to build cast iron cranes. The very first cast iron crane built by Germany was made within Neuburg.
