The hydraulic truck crane is a specialized mobile crane which uses hydraulic power to raise and transport thousands of pounds. Hydraulics uses 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 vital in constructing major projects like bridges, airports, buildings and roadways. A crane can accomplish in minutes jobs which will normally take hundreds of men and many hours to complete.
These remarkable machinery have played a vital role in building cities, houses, individual buildings and entire nations throughout the ages. Even the Great Pyramids in Egypt were likely built utilizing basic cranes to enable the heaviest materials in one of the most remarkable construction projects ever.
The first cranes were established in 3000 B.C. Egypt in the reign of King Ramses. This lifting mechanism was initially utilized to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized 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These cranes were originally made out of wood.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 need stronger and larger machines. Hick & Rothwell developed the first cast iron cranes within Bolton, England, in the year 1834. This machinery could lift as much as 2 tons. That very same year, the addition of wire rope was 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 larger capacity to lift heavy weights.
Eventually, 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 started to make cast iron cranes. The very first cast iron crane made by Germany was built in Neuburg.
