The hydraulic truck crane is a specific mobile crane which utilizes hydraulic power to raise and move thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing on the pistons of the boom in opposite directions so as to lift thousands of pounds. Hydraulic truck cranes are essential in building major projects like for example bridges, airports, buildings and roads. A crane could complete in minutes jobs which would normally take many hours and hundreds of men to complete.
These impressive machinery have played a vital role in building cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were probably built using basic cranes to allow the heaviest supplies in one of the most awesome construction projects of all time.
The very first cranes were established in 3000 B.C. Egypt in the reign of King Ramses. This lifting device was initially utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These mechanism were utilized to build a whole nation throughout the 5th century B.C.
Originally, 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 evolve. Hick & Rothwell designed the first cast iron cranes within Bolton, England, in 1834. This machine was capable of lifting as much as 2 tons. That 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 enabled 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 make cast iron cranes 4 years later. The first cast iron crane built by Germany was made within Neuburg.
