Hydraulic truck cranes are a particular type of mobile crane. These cranes use hydraulics and can lift thousands of pounds. Hydraulics utilizes forces being transmitted through oil pushing in opposite directions on the pistons of the boom so as to lift thousands of pounds. Hydraulic truck cranes are really essential in constructing major projects like bridges, airports, roads and buildings. A crane can accomplish in minutes tasks that would normally take lots of hours and hundreds of men to complete.
These impressive machines have played a vital part in constructing houses, cities, individual buildings and entire nations throughout the ages. Even the Great Pyramids within Egypt were likely built utilizing basic cranes to allow the heaviest supplies in one of the most amazing construction projects of all time.
The very first representation of a crane was featured during King Ramses' reign in Egypt during 3000 B.C. This was a portrayal of a lifting device that was used to collect water. The first official "cranes" appeared in Ancient Greece. These devices were utilized to create an entire nation during 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 bigger did these equipments evolve. Hick & Rothwell designed the very first cast iron cranes in 1834, in Bolton, England. This machine was capable of lifting as much as 2 tons. That 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 larger capacity for lifting heavy weights.
Ultimately, the wire ropes were weaved together to be able to form an even more powerful strength. This wire formation also brought the added advantage of flexibility. 4 years later, Germany began to make cast iron cranes. The first cast iron crane built by Germany was made in Neuburg.
