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 pistons of the boom in order to lift thousands of pounds. Hydraulic truck cranes are vital in constructing major projects like for example airports, bridges, buildings and roads. A crane could complete in minutes tasks which will normally take lots of hours and hundreds of men to accomplish.
These impressive equipments have played a very important part in building cities, houses, individual buildings and entire nations throughout the ages. Even Egypt's Great Pyramids were probably built utilizing basic cranes to allow the heaviest supplies in one of the most remarkable construction projects ever.
The first cranes were established during 3000 B.C. Egypt during the reign of King Ramses. This lifting mechanism was originally utilized to collect water. The first official "cranes" appeared during Ancient Greece. These mechanism were used to create an entire nation 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These cranes were originally made out of wood.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 need stronger and bigger equipments. Hick & Rothwell developed the first cast iron cranes within Bolton, England, during the year 1834. This equipment could 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 stronger and more durable. This addition allowed cranes to have a bigger capacity for lifting heavy weights.
Ultimately, the wire ropes were weaved together to be able to form an even more powerful strength. This wire formation also brought the added advantage of flexibility. 4 years later, Germany began to make cast iron cranes. The very first cast iron crane made by Germany was built within Neuburg.
