The hydraulic truck crane is a particular mobile crane which uses hydraulic power to raise and move thousands of pounds. Hydraulics makes use of 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 essential in building major projects like bridges, airports, roadways and buildings. A crane could complete in minutes tasks which would normally take a lot of hours and hundreds of men to accomplish.
These remarkable machinery have played a very important role in building houses, cities, individual buildings and entire nations throughout the ages. Even the Great Pyramids within Egypt were probably constructed with the help of basic cranes to enable the heaviest supplies in one of the most remarkable construction projects of all time.
The very first cranes were established during 3000 B.C. Egypt in the reign of King Ramses. This lifting device was originally utilized to collect water. The very first official "cranes" appeared in Ancient Greece. These devices were utilized to create an entire nation in the 5th century B.C.
Originally, cranes were first made out of wood. It wasn't until the designers constructing dockyards decided they needed something stronger and bigger did these equipments develop. Hick & Rothwell designed the first cast iron cranes in Bolton, England, in the year 1834. This machine can lift 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 in order to form an even more powerful strength. This wire formation also brought the added benefit of flexibility. 4 years later, Germany began to make cast iron cranes. The very first cast iron crane made by Germany was made in Neuburg.
