Hydraulic truck cranes are a particular 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 in order to lift thousands of pounds. Hydraulic truck cranes are very vital in constructing major projects like airports, bridges, roads and buildings. A crane could accomplish in minutes tasks which would normally take many hours and hundreds of men to complete.
These remarkable machines have played a very important role in constructing cities, houses, individual buildings and entire nations throughout the ages. Even Egypt's Great Pyramids were probably built utilizing basic cranes to enable the heaviest materials in one of the most amazing construction projects of all time.
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 during 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These cranes were originally made out of wood.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 started to change when dockyards began to require stronger and bigger machinery. Hick & Rothwell designed the very first cast iron cranes within Bolton, England, during the year 1834. This machinery could lift up to 2 tons. That very same year, wire ropes were added to the crane by Herr Albert Sr. who was an Official of the German Superior Board. The wire rope made the crane more durable and stronger. This addition allowed cranes to have a bigger capacity for lifting heavy weights.
Ultimately, the wire ropes were weaved together to be able to form an even more powerful strength. This wire formation also brought the added benefit of flexibility. Germany started to make cast iron cranes 4 years later. The very first cast iron crane made by Germany was built in Neuburg.
