The purpose of Tower cranes is to lift up, carry and drop down heavy construction material and substances. Since it is a mechanical device that is normally used in the manufacturing of heavy weight equipment, it is appropriate for individuals related to construction business. Therefore, these cranes are generally used and seen at almost all the sites that are under construction.
According to many experts, Tower cranes are the contemporary kinds of cranes that are made using the most recent and modern technology. It is because of its uplifting ability and height that these cranes are mostly found at sites where tall buildings are being constructed. These cranes feature long post, which is fixed to the land or ground and also two arms, one, which is horizontally positioned, and another, which is diagonally balanced disproportionately at the top of the crane tower. The function of the long extended arm is to hold the lifting gear whereas the function of the short arm is to hold building blocks.
Now the question arises that since Tower cranes have no such support on both sides, how does it actually operate or function? In order to have a clear understanding on how these cranes operate, it is essential to gain knowledge regarding the basic parts of these cranes. The cranes consist of three basic parts, base, mast (commonly known as a tower) and a slewing unit. The Base serves the purpose of providing support to the tower crane and is fastened tightly to a large and solid concrete pad. The mast or the tower provides height to the crane and is directly connected to the base. Last but not the least, the slewing unit is a motor, which enables the crane to revolve or rotate at different directions.
As discussed earlier, Tower cranes are manufactured using the most recent technology, and intelligence when combined with this remarkable technology gave origin to this effective machinery that has made the construction work much easier. The entire crane is not built in one go, but is created in parts a few weeks or months before its actual operation. A Tower crane is a great invention and has amazed people with its incredible attributes and performance.
Though Tower cranes have the capacity to load up to 40,000 pounds, experts suggest that it is not recommendable to load this heavy weight. These cranes have the capacity to rise up to hundreds of feet high. The construction team utilizes these cranes to lift up concrete, steel and other large objects like generators, acetylene torches and various other heavy building substances. If you ever get a chance to look at how these cranes operate you will be amazed of how it can lift such heavy weight and is able to grow up taller as the building increases in height.
