Hydraulic truck cranes are a specialized type of mobile crane. These cranes use hydraulics and can lift thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing on the boom's pistons in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are vital in building major projects like bridges, airports, buildings and roads. A crane can complete in minutes jobs that would normally take hundreds of men and a lot of hours to accomplish.
The great machinery are commonly used in the construction of cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably constructed using basic cranes to allow the heaviest materials in one of the most amazing construction projects of all time.
The first cranes were established during 3000 B.C. Egypt during King Ramses' reign. This lifting mechanism was originally used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized to create a whole nation 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 larger machines. Hick & Rothwell designed the first cast iron cranes in the year 1834, within Bolton, England. This machinery can lift up to 2 tons. That same year, wire ropes were added to the crane by an Official of the German Superior Board, Herr Albert Sr. The wire rope made the crane stronger and more durable. 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 started to make cast iron cranes. The very first cast iron crane built by Germany was made in Neuburg.
