Hydraulic truck cranes are a particular kind of mobile crane. These cranes utilize hydraulics and could lift thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing in opposite directions on the pistons of the boom in order to lift thousands of pounds. Hydraulic truck cranes are really essential in building major projects like bridges, airports, buildings and roads. A crane can complete in minutes tasks that will normally take a lot of hours and hundreds of men to complete.
These impressive machines have played a very important role in constructing cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely built using basic cranes to enable the heaviest supplies in one of the most remarkable 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 that was utilized to collect water. The very first official "cranes" appeared during Ancient Greece. These devices were utilized to build a whole 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 machines evolve. Hick & Rothwell developed the very first cast iron cranes in Bolton, England, during 1834. This machine was capable of lifting up to 2 tons. That same year, wire ropes were added to the crane by Herr Albert Sr. who was an Official of the German Superior Board. 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. Germany began to make cast iron cranes 4 years later. The very first cast iron crane built by Germany was built in Neuburg.
