Looking into the skyline of a larger city, one will find tower cranes erected near skyscrapers and tall buildings. These large structures are described as a central shaft which is counterweighted with a long boom utilized to balance the load of the crane. There are numerous kinds of tower crane types. These lattice-woven structures are available for special applications. Some common kinds include bottom-slewing, top-slewing and self-erecting models. Slewing means turning around a fixed point. The main kind of top-slewing tower crane that is used in construction these days is the horizontal boom. These eye-catching structures are found all over the globe.
How to Erect a Tower Crane
Tower cranes are normally utilized on construction sites to transport materials from high to low places and vice versa. They are used for high-rise structures in areas where a wheel-mounted crane is not big enough to finish out the work. Only trained professionals should be the ones to build a tower crane. To be able to keep everybody safe, this job has to be carried out by experts. There is a high possibility of collapse, that could cause extensive damage and loss if you try to raise it on your own with hardly any experience.
In preparation of erecting the crane, an excavator is utilized to dig out a big pit that is utilized for the base of the crane. The hole is then filled with concrete. Steel anchors are set into the concrete, and then, the first part of the crane's mast is connected. The concrete is required to cure for 24 hours.
The first mast section can be bolted to the anchors, when the base has finally set. By using your spirit level, one can make certain that the mast is vertical. Afterward, fix another section of the mast by initially using bolts and keep repeating this process until your desired height has been attained. It would be necessary to utilize a scissor lift or a telescoping boom to be able to carry out this step.
