The hydraulic truck crane is a specific mobile crane that uses hydraulic power to raise and move thousands of pounds. Hydraulics utilizes 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 important in constructing major projects like bridges, airports, streets and buildings. A crane can accomplish in minutes tasks that would normally take hundreds of men and many hours to accomplish.
The vast equipments are commonly utilized in the construction of cities, homes, whole nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed with the help of basic cranes to enable the heaviest supplies in one of the most remarkable construction projects ever.
The first representation of a crane was featured during King Ramses' reign within 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 mechanism were utilized to build a whole country throughout the 5th century B.C.
Initially, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they required something stronger and bigger did these equipments evolve. Hick & Rothwell designed the first cast iron cranes in Bolton, England, during 1834. This machine was capable of lifting as much as 2 tons. That very same year, the addition of wire rope was added to the crane by Herr Albert Sr. who was an Official of the German Superior Board. The wire rope made the crane more durable and stronger. 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. Germany started to build cast iron cranes 4 years later. The first cast iron crane made by Germany was built in Neuburg.
