The hydraulic truck crane is a specific mobile crane which utilizes hydraulic power to raise and move thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing in opposite directions on the boom's pistons so as to lift thousands of pounds. Hydraulic truck cranes are very essential in building major projects like airports, bridges, buildings and roadways. A crane could complete in minutes jobs which will normally take hundreds of men and many hours to accomplish.
These remarkable machinery have played a very important role in building cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were probably constructed using basic cranes to allow the heaviest supplies in one of the most awesome construction projects ever.
The very first representation of a crane was showcased during the reign of King Ramses in Egypt in 3000 B.C. This was a portrayal of a lifting device which was utilized to collect water. The first official "cranes" appeared in Ancient Greece. These devices were used to build an entire 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 bigger did these machines develop. Hick & Rothwell designed the very first cast iron cranes in Bolton, England, in the year 1834. This equipment was capable of lifting up to 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 stronger and more durable. This addition enabled cranes to have a larger capacity to lift 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 benefit of flexibility. Germany began to make cast iron cranes 4 years later. The very first cast iron crane made by Germany was made in Neuburg.
