Hydraulic truck cranes are a specific kind of mobile crane. These cranes utilize 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 vital in constructing major projects like airports, bridges, buildings and roadways. A crane can accomplish in minutes tasks that will normally take hundreds of men and many hours to complete.
The vast machines are usually utilized in the construction of cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were likely built utilizing basic cranes to allow the heaviest materials in one of the most remarkable construction projects ever.
The first representation of a crane was featured during the reign of King Ramses within Egypt in 3000 B.C. This was a portrayal of a lifting device which was used to collect water. The very first official "cranes" appeared during Ancient Greece. These devices were used to build an entire nation during 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 bigger did these equipments develop. Hick & Rothwell developed the very first cast iron cranes in 1834, in Bolton, England. This equipment 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 enabled cranes to have a bigger capacity for lifting 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 within Neuburg.
