The hydraulic truck crane is a specific mobile crane which uses hydraulic power to raise and move thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing on the boom's pistons in opposite directions in order to lift thousands of pounds. Hydraulic truck cranes are vital in building major projects like bridges, airports, streets and buildings. A crane can complete in minutes tasks that would normally take hundreds of men and a lot of hours to accomplish.
These remarkable machines have played a very important role in building cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids in Egypt were probably constructed utilizing basic cranes to allow the heaviest materials in one of the most awesome construction projects ever.
The first representation of a crane was featured during the reign of King Ramses in Egypt in 3000 B.C. This was a portrayal of a lifting mechanism that was utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These devices were used to build a whole country in 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 equipments develop. Hick & Rothwell designed the very first cast iron cranes within Bolton, England, in the year 1834. This machine was capable of lifting as much as 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 larger 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 began to make cast iron cranes. The first cast iron crane made by Germany was built within Neuburg.
