Hydraulic truck cranes are a particular kind of mobile crane. These cranes utilize hydraulics and are able to lift thousands of pounds. Hydraulics uses forces being transmitted through oil pushing in opposite directions on the boom's pistons so as to lift thousands of pounds. Hydraulic truck cranes are important in building major projects such as bridges, airports, buildings and streets. A crane can accomplish in minutes tasks that will normally take lots of hours and hundreds of men to accomplish.
These impressive equipments have played a very important role in building houses, cities, individual buildings and entire nations throughout the ages. Even the Great Pyramids in Egypt were likely built utilizing basic cranes to allow the heaviest materials in one of the most awesome construction projects of all time.
The first cranes were established in 3000 B.C. Egypt in King Ramses' reign. This lifting mechanism was originally utilized to collect water. The first official "cranes" appeared during Ancient Greece. These devices were used to build a whole nation throughout the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers building dockyards decided they required something stronger and bigger did these machinery develop. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, during the year 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 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.
The wire ropes were weaved together forming a more powerful rope with even more strength. The newly formed wire also added more flexibility. Germany began to build cast iron cranes 4 years later. The very first cast iron crane made by Germany was built in Neuburg.
