The hydraulic truck crane is a particular mobile crane that utilizes hydraulic power to lift and transport thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing in opposite directions on the pistons of the boom in order to lift thousands of pounds. Hydraulic truck cranes are vital in constructing major projects such as bridges, airports, buildings and streets. A crane can accomplish in minutes tasks which would normally take lots of hours and hundreds of men to accomplish.
The vast machinery are usually used in the construction of cities, homes, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely constructed utilizing basic cranes to enable the heaviest supplies in one of the most amazing construction projects of all time.
The first representation of a crane was showcased during the reign of King Ramses in Egypt during 3000 B.C. This was a portrayal of a lifting device which was used to collect water. The very first official "cranes" appeared in Ancient Greece. These mechanism were utilized to create an entire nation during the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes began to change when dockyards began to require stronger and bigger equipments. Hick & Rothwell developed the very first cast iron cranes in Bolton, England, during 1834. This machinery was capable of lifting up to 2 tons. That very 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 more durable and stronger. This addition allowed cranes to have a larger capacity for lifting 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 built in Neuburg.
