The hydraulic truck crane is a specific mobile crane which utilizes hydraulic power to lift and move thousands of pounds. Hydraulics uses 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 vital in constructing major projects such as airports, bridges, buildings and roadways. A crane could complete in minutes jobs which would normally take a lot of hours and hundreds of men to accomplish.
The vast machines are commonly used in the building of cities, homes, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely constructed using basic cranes to enable the heaviest supplies in one of the most awesome construction projects of all time.
The very first cranes were established during 3000 B.C. Egypt during King Ramses' reign. This lifting device was initially utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These mechanism were utilized to create an entire nation in 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 machines develop. Hick & Rothwell designed the very first cast iron cranes in Bolton, England, during 1834. This machine can lift up to 2 tons. That very 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 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. Germany began to build cast iron cranes 4 years later. The first cast iron crane built by Germany was built in Neuburg.
