Looking into the skyline of a bigger city, one will find tower cranes erected beside skyscrapers and tall buildings. These big structures are described as a central shaft that is counterweighted with a long boom utilized to balance the load of the crane. There are many kinds of tower crane types. These lattice-woven structures are available for particular applications. Some popular types include bottom-slewing, top-slewing and self-erecting models. Slewing means turning around a fixed point. The main type of top-slewing tower crane that is used in construction nowadays is the horizontal boom. These eye-catching structures are seen throughout the globe.
How to Erect a Tower Crane
Tower cranes are normally used on construction sites to move supplies from low to high places and vice versa. They are used for high-rise structures in areas where a wheel-mounted crane is not large enough to finish out the work. Just trained professionals must be the ones to build a tower crane. To be able to keep everyone safe, this task must be carried out by professionals. There is a high possibility of collapse, that could cause extensive damage and loss if you try to built it yourself with hardly any experience.
When preparing to build the crane, an excavator needs to dig out a pit big enough for the crane's base. After that, this hole is filled with concrete. Steel anchors are set into the concrete, and afterward, the first part of the crane's mast is connected. The concrete is required to cure for 24 hours.
The first mast part can be bolted to the anchors, when the base has finally set. By utilizing your spirit level, one can ensure that the mast is vertical. Afterwards, fix another part of the mast by first using bolts and keep repeating this method until your desired height has been attained. It would be necessary to utilize a scissor lift or a telescoping boom in order to do this step.
