Hydraulic truck cranes are a specialized kind of mobile crane. These cranes utilize hydraulics and could lift 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 constructing major projects such as bridges, airports, buildings and roads. A crane could complete in minutes tasks that would normally take hundreds of men and a lot of hours to complete.
These impressive equipments have played a very important role in constructing houses, cities, individual buildings and entire nations throughout the ages. Even Egypt's Great Pyramids were probably built utilizing basic cranes to allow the heaviest supplies in one of the most remarkable construction projects ever.
The very first cranes were established in 3000 B.C. Egypt during the reign of King Ramses. This lifting device was originally used to collect water. The first official "cranes" appeared during Ancient Greece. These devices were utilized to create a whole 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 larger did these machinery evolve. Hick & Rothwell designed the very first cast iron cranes within Bolton, England, during the year 1834. This machinery could lift up to 2 tons. That 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 to lift 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 advantage of flexibility. 4 years later, Germany began to build cast iron cranes. The first cast iron crane made by Germany was made in Neuburg.
