Hydraulic truck cranes are a specific kind of mobile crane. These cranes utilize hydraulics and can lift thousands of pounds. Hydraulics uses forces being transmitted through oil pushing in opposite directions on the boom's pistons so as to lift thousands of pounds. Hydraulic truck cranes are essential in constructing major projects like bridges, airports, buildings and roadways. A crane can accomplish in minutes tasks which would normally take lots of hours and hundreds of men to accomplish.
The great machines are normally used in the building of cities, houses, whole nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely built using basic cranes to enable the heaviest materials in one of the most remarkable construction projects ever.
The very first representation of a crane was showcased during King Ramses' reign within Egypt in 3000 B.C. This was a portrayal of a lifting device which was used to collect water. The first official "cranes" appeared during Ancient Greece. These devices were utilized to create a whole country throughout the 5th century B.C.
Initially, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they needed something stronger and bigger did these machinery evolve. Hick & Rothwell developed the first cast iron cranes in Bolton, England, during the year 1834. This equipment was capable of lifting up to 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 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 build cast iron cranes. The very first cast iron crane built by Germany was made in Neuburg.
