The hydraulic truck crane is a specialized mobile crane that uses hydraulic power to raise and move 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 essential in constructing major projects like for instance bridges, airports, buildings and streets. A crane could complete in minutes tasks which will normally take hundreds of men and a lot of hours to accomplish.
The great equipments are usually used in the construction of cities, houses, entire nations and individual buildings throughout the ages. Even the Great Pyramids within Egypt were likely built using basic cranes to enable the heaviest materials in one of the most awesome construction projects of all time.
The 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 which was utilized to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized to create an entire country throughout the 5th century B.C.
These cranes were initially made out of wood. The designs of cranes began to change when dockyards started to require stronger and larger machines. Hick & Rothwell designed the first cast iron cranes in Bolton, England, in the year 1834. This machinery was capable of lifting up to 2 tons. That very same year, wire ropes were 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 make cast iron cranes. The very first cast iron crane made by Germany was made within Neuburg.
