The hydraulic truck crane is a particular mobile crane that uses hydraulic power to lift and move thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing in opposite directions on the pistons of the boom so as to lift thousands of pounds. Hydraulic truck cranes are vital in constructing major projects like for example airports, bridges, buildings and streets. A crane can complete in minutes jobs that will normally take hundreds of men and a lot of hours to complete.
These remarkable machines have played a vital part in constructing cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably built using basic cranes to enable the heaviest supplies in one of the most awesome construction projects of all time.
The very first cranes were established in 3000 B.C. Egypt in King Ramses' reign. This lifting mechanism was initially utilized to collect water. The first official "cranes" appeared during Ancient Greece. These devices were used to build a whole country throughout the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they required something stronger and larger did these equipments develop. Hick & Rothwell designed the very first cast iron cranes within Bolton, England, in 1834. This equipment was capable of lifting 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 enabled cranes to have a bigger capacity for lifting heavy weights.
Eventually, 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. 4 years later, Germany started to make cast iron cranes. The very first cast iron crane built by Germany was made within Neuburg.
