Hydraulic truck cranes are a specialized kind of mobile crane. These cranes make use of hydraulics and could lift thousands of pounds. Hydraulics utilizes 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 really vital in constructing major projects like bridges, airports, buildings and streets. A crane could complete in minutes jobs that will normally take a lot of hours and hundreds of men to complete.
These remarkable equipments have played a very important role in constructing cities, houses, individual buildings and entire nations throughout the ages. Even the Great Pyramids in Egypt were probably constructed using basic cranes to allow the heaviest materials in one of the most amazing construction projects ever.
The first representation of a crane was showcased during King Ramses' reign within Egypt in 3000 B.C. This was a portrayal of a lifting device that was utilized to collect water. The first official "cranes" appeared in Ancient Greece. These devices were used to build a whole country during the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes started to change when dockyards began to need stronger and bigger machinery. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, during 1834. This equipment can lift as much as 2 tons. That 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.
The wire ropes were weaved together forming a more powerful rope with even more strength. The newly formed wire also added more flexibility. 4 years later, Germany began to build cast iron cranes. The first cast iron crane built by Germany was built within Neuburg.
