Hydraulic truck cranes are a particular type of mobile crane. These cranes make use of hydraulics and can lift thousands of pounds. Hydraulics uses 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 important in constructing major projects like for example bridges, airports, buildings and roads. A crane could complete in minutes tasks that would normally take many hours and hundreds of men to complete.
The great machinery are normally used in the building of cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were probably built with the help of basic cranes to enable the heaviest supplies in one of the most amazing construction projects ever.
The first cranes were established during 3000 B.C. Egypt in the reign of King Ramses. This lifting mechanism was originally used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were used to build a whole country during the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they needed something stronger and larger did these machines develop. Hick & Rothwell developed the very first cast iron cranes in Bolton, England, in 1834. This equipment was capable of lifting as much as 2 tons. That very same year, the addition of wire rope was 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 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. Germany started to make cast iron cranes 4 years later. The very first cast iron crane built by Germany was built within Neuburg.
