The hydraulic truck crane is a particular mobile crane which utilizes hydraulic power to raise and move thousands of pounds. Hydraulics makes use of forces being transmitted through oil pushing on the pistons of the boom in opposite directions in order to lift thousands of pounds. Hydraulic truck cranes are really important in constructing major projects like for instance bridges, airports, buildings and streets. A crane could accomplish in minutes jobs that would normally take a lot of hours and hundreds of men to accomplish.
These remarkable machines have played a very important part in building houses, cities, individual buildings and entire nations throughout the ages. Even Egypt's Great Pyramids were likely constructed utilizing basic cranes to enable the heaviest supplies in one of the most awesome construction projects of all time.
The first representation of a crane was showcased during the reign of King Ramses in Egypt during 3000 B.C. This was a portrayal of a lifting device that was used to collect water. The very first official "cranes" appeared during Ancient Greece. These mechanism were utilized to build an entire country during the 5th century B.C.
These cranes were originally made out of wood. The designs of cranes started to change when dockyards began to require stronger and bigger equipments. Hick & Rothwell designed the very first cast iron cranes in Bolton, England, during 1834. This machinery could lift as much as 2 tons. That same year, the addition of wire rope was 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 to lift 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 first cast iron crane made by Germany was made in Neuburg.
