Hydraulic truck cranes are a particular type of mobile crane. These cranes utilize hydraulics and are able to lift thousands of pounds. Hydraulics uses forces being transmitted through oil pushing on the pistons of the boom in opposite directions in order to lift thousands of pounds. Hydraulic truck cranes are very important in building major projects like for example bridges, airports, buildings and roads. A crane can accomplish in minutes jobs which would normally take lots of hours and hundreds of men to accomplish.
The vast equipments are usually utilized in the building of cities, houses, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were probably constructed with the help of basic cranes to allow the heaviest supplies in one of the most awesome construction projects ever.
The very first cranes were established in 3000 B.C. Egypt in the reign of King Ramses. This lifting device was originally utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These devices were used 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 needed something stronger and larger did these equipments evolve. Hick & Rothwell designed the very first cast iron cranes in Bolton, England, in the year 1834. This machine can lift as much as 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 stronger and more durable. This addition enabled cranes to have a bigger capacity for lifting heavy weights.
Eventually, the wire ropes were weaved together in order to form an even more powerful strength. This wire formation also brought the added benefit of flexibility. Germany started to build cast iron cranes 4 years later. The very first cast iron crane made by Germany was built within Neuburg.
