The hydraulic truck crane is a specific mobile crane that utilizes hydraulic power to raise and move thousands of pounds. Hydraulics uses forces being transmitted through oil pushing in opposite directions on the boom's pistons in order to lift thousands of pounds. Hydraulic truck cranes are really important in constructing major projects like for example bridges, airports, roadways and buildings. A crane can accomplish in minutes jobs that would normally take hundreds of men and many hours to accomplish.
These remarkable machinery have played a vital part in building houses, cities, individual buildings and entire nations throughout the ages. Even Egypt's Great Pyramids were probably constructed with the help of basic cranes to allow the heaviest supplies in one of the most remarkable construction projects ever.
The very first representation of a crane was featured during the reign of King Ramses in Egypt during 3000 B.C. This was a portrayal of a lifting device that was used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized to build a whole country in the 5th century B.C.
Initially, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they required something stronger and larger did these machines develop. Hick & Rothwell designed the first cast iron cranes within Bolton, England, in 1834. This machine could lift as much as 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 stronger and more durable. 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 began to build cast iron cranes 4 years later. The very first cast iron crane built by Germany was made in Neuburg.
