Hydraulic truck cranes are a specialized type of mobile crane. These cranes utilize hydraulics and are able to lift thousands of pounds. Hydraulics uses 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 essential in constructing major projects like bridges, airports, streets and buildings. A crane can complete in minutes tasks which will normally take many hours and hundreds of men to accomplish.
The great machinery are usually used in the construction of cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely constructed with the help of basic cranes to enable the heaviest supplies in one of the most amazing construction projects ever.
The first cranes were established during 3000 B.C. Egypt in the reign of King Ramses. This lifting mechanism was originally used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized to build a whole country in the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they needed something stronger and larger did these machines develop. Hick & Rothwell developed the first cast iron cranes in the year 1834, in Bolton, England. This machine can lift as much as 2 tons. That 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 bigger 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 benefit of flexibility. 4 years later, Germany began to make cast iron cranes. The very first cast iron crane made by Germany was made in Neuburg.
