Hydraulic truck cranes are a specific kind of mobile crane. These cranes utilize hydraulics and are able to lift thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing on the pistons of the boom in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are essential in constructing major projects like for instance airports, bridges, buildings and roadways. A crane could accomplish in minutes jobs which will normally take hundreds of men and many hours to accomplish.
These impressive machines have played a very important role in constructing cities, houses, individual buildings and entire nations throughout the ages. Even the Great Pyramids within Egypt were likely built utilizing basic cranes to allow the heaviest materials in one of the most remarkable construction projects of all time.
The first cranes were established during 3000 B.C. Egypt in the reign of King Ramses. This lifting mechanism was first used to collect water. The first official "cranes" appeared during Ancient Greece. These devices were used to build a whole nation throughout the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes began to change when dockyards started to require stronger and bigger machinery. Hick & Rothwell designed the first cast iron cranes within Bolton, England, in the year 1834. This equipment was capable of lifting as much as 2 tons. That very 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 more durable and stronger. This addition enabled cranes to have a bigger capacity to lift 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 began to make cast iron cranes. The first cast iron crane made by Germany was built within Neuburg.
