Hydraulic truck cranes are a specific type of mobile crane. These cranes use hydraulics and could lift 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 really vital in constructing major projects such as airports, bridges, roads and buildings. A crane could complete in minutes jobs which will normally take hundreds of men and many hours to accomplish.
The great machines are usually used in the building of cities, houses, whole nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed using basic cranes to allow the heaviest supplies 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 device that was utilized to collect water. The first official "cranes" appeared in Ancient Greece. These devices were used to create a whole nation throughout the 5th century B.C.
Initially, 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 develop. Hick & Rothwell designed the first cast iron cranes in Bolton, England, during 1834. This equipment can lift 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 allowed cranes to have a bigger capacity to lift heavy weights.
Ultimately, the wire ropes were weaved together to be able to form an even more powerful strength. This wire formation also brought the added benefit of flexibility. 4 years later, Germany started to make cast iron cranes. The very first cast iron crane made by Germany was made within Neuburg.
