Hydraulic truck cranes are a specific type of mobile crane. These cranes make use of hydraulics and can lift thousands of pounds. Hydraulics utilizes 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 very essential in constructing major projects such as bridges, airports, buildings and streets. A crane can accomplish in minutes jobs that will normally take lots of hours and hundreds of men to complete.
The great machines are usually utilized in the construction of cities, homes, whole nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely built using basic cranes to enable the heaviest materials in one of the most awesome construction projects of all time.
The first representation of a crane was showcased during King Ramses' reign within Egypt in 3000 B.C. This was a portrayal of a lifting device that was used to collect water. The very first official "cranes" appeared during Ancient Greece. These devices were used to build an entire country during the 5th century B.C.
Initially, cranes were first made out of wood. It wasn't until the designers building dockyards decided they required something stronger and bigger did these machinery develop. Hick & Rothwell designed the very first cast iron cranes during 1834, in Bolton, England. This machine was capable of lifting up to 2 tons. That very same year, wire ropes were 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 allowed cranes to have a bigger capacity to lift 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 very first cast iron crane made by Germany was built within Neuburg.
