Hydraulic truck cranes are a specialized kind of mobile crane. These cranes use hydraulics and are able to lift thousands of pounds. Hydraulics makes use of 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, roadways and buildings. A crane could complete in minutes tasks that will normally take hundreds of men and lots of hours to accomplish.
These impressive machines have played a vital role in constructing houses, cities, individual buildings and entire nations throughout the ages. Even the Great Pyramids within Egypt were probably built using basic cranes to allow the heaviest materials in one of the most amazing construction projects ever.
The first cranes were established in 3000 B.C. Egypt during the reign of King Ramses. This lifting mechanism was originally utilized to collect water. The very first official "cranes" appeared during Ancient Greece. These devices were utilized to create 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 required something stronger and bigger did these equipments evolve. Hick & Rothwell designed the very first cast iron cranes within Bolton, England, during 1834. This equipment can lift up to 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 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. Germany started to make cast iron cranes 4 years later. The first cast iron crane built by Germany was made within Neuburg.
