Hydraulic truck cranes are a specialized kind of mobile crane. These cranes make use of hydraulics and could lift thousands of pounds. Hydraulics utilizes 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 very essential in building major projects like bridges, airports, roads and buildings. A crane could accomplish in minutes jobs which would normally take hundreds of men and many hours to complete.
These impressive machines have played a vital role in building cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably built utilizing basic cranes to allow the heaviest materials in one of the most amazing construction projects ever.
The very first cranes were established in 3000 B.C. Egypt during the reign of King Ramses. This lifting device was originally used to collect water. The first official "cranes" appeared in Ancient Greece. These mechanism were utilized to build a whole country throughout the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes began to change when dockyards began to need stronger and bigger equipments. Hick & Rothwell developed the first cast iron cranes in the year 1834, within Bolton, England. This machine 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 more durable and stronger. This addition allowed cranes to have a larger capacity for lifting heavy weights.
Eventually, the wire ropes were weaved together in order to form an even more powerful strength. This wire formation also brought the added benefit of flexibility. 4 years later, Germany started to build cast iron cranes. The very first cast iron crane built by Germany was made within Neuburg.
