Hydraulic truck cranes are a specific type of mobile crane. These cranes use hydraulics and could lift thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing on the pistons of the boom in opposite directions in order to lift thousands of pounds. Hydraulic truck cranes are important in constructing major projects like airports, bridges, roadways and buildings. A crane could complete in minutes jobs that will normally take hundreds of men and lots of hours to complete.
The vast equipments are commonly used in the construction of cities, houses, entire nations and individual buildings 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 of all time.
The first cranes were established during 3000 B.C. Egypt during the reign of King Ramses. This lifting mechanism was first utilized to collect water. The first official "cranes" appeared during Ancient Greece. These mechanism were used to build an entire nation during the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes began to change when dockyards started to need stronger and bigger machines. Hick & Rothwell developed the first cast iron cranes during the year 1834, in Bolton, England. This machinery can 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 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. Germany began to build cast iron cranes 4 years later. The first cast iron crane made by Germany was made in Neuburg.
