Hydraulic truck cranes are a particular kind of mobile crane. These cranes use hydraulics and can lift thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing in opposite directions on the boom's pistons in order to lift thousands of pounds. Hydraulic truck cranes are really important in building major projects like for instance airports, bridges, streets and buildings. A crane could accomplish in minutes tasks which will normally take a lot of hours and hundreds of men to complete.
The vast equipments are commonly used in the construction of cities, homes, entire nations and individual buildings throughout the ages. Even Egypt's Great Pyramids were likely constructed utilizing basic cranes to allow the heaviest materials in one of the most amazing construction projects ever.
The first cranes were established in 3000 B.C. Egypt during the reign of King Ramses. This lifting mechanism was first used to collect water. The very first official "cranes" appeared in Ancient Greece. These mechanism were utilized to create 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 larger did these equipments develop. Hick & Rothwell developed the very first cast iron cranes within Bolton, England, in 1834. This machine was capable of lifting up to 2 tons. That very same year, the addition of wire rope was 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 larger 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 started to build cast iron cranes. The very first cast iron crane built by Germany was built in Neuburg.
