Hydraulic truck cranes are a specialized type of mobile crane. These cranes utilize hydraulics and could lift thousands of pounds. Hydraulics utilizes 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 very vital in constructing major projects like airports, bridges, streets and buildings. A crane could complete in minutes tasks that will normally take hundreds of men and a lot of hours to accomplish.
These impressive machinery 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 utilizing basic cranes to allow the heaviest materials in one of the most amazing construction projects of all time.
The very first representation of a crane was showcased during the reign of King Ramses in Egypt during 3000 B.C. This was a portrayal of a lifting mechanism which was utilized to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized to create an entire country throughout the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes started to change when dockyards began to require stronger and larger equipments. Hick & Rothwell designed the very first cast iron cranes within Bolton, England, in 1834. This machine can lift as much as 2 tons. That 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 larger capacity for lifting heavy weights.
Ultimately, the wire ropes were weaved together in order to form an even more powerful strength. This wire formation also brought the added advantage of flexibility. 4 years later, Germany began to build cast iron cranes. The very first cast iron crane made by Germany was made within Neuburg.
