Hydraulic truck cranes are a particular type of mobile crane. These cranes make use of hydraulics and are able to lift thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing on the boom's pistons in opposite directions in order to lift thousands of pounds. Hydraulic truck cranes are very vital in building major projects like bridges, airports, buildings and roadways. A crane can accomplish in minutes tasks which will normally take many hours and hundreds of men to accomplish.
The great equipments are normally utilized in the building of cities, houses, whole nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were probably built utilizing basic cranes to allow the heaviest materials in one of the most amazing construction projects of all time.
The first representation of a crane was showcased during King Ramses' reign in Egypt in 3000 B.C. This was a portrayal of a lifting mechanism which was utilized to collect water. The first official "cranes" appeared in Ancient Greece. These mechanism were utilized to build an entire nation during 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 equipments develop. Hick & Rothwell developed the first cast iron cranes in Bolton, England, during the year 1834. This equipment was capable of lifting 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 stronger and more durable. This addition enabled 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. 4 years later, Germany began to build cast iron cranes. The first cast iron crane made by Germany was built in Neuburg.
