Looking into the skyline of a bigger city, one would find tower cranes constructed near tall buildings and skyscrapers. These big structures are described as a central shaft that is counterweighted with a long boom used to balance the load of the crane. There are many models of tower crane types. These lattice-woven structures are available for particular applications. Some common types consist of self-erecting, bottom-slewing and top-slewing models. Slewing refers to turning around a fixed point. The main kind of top-slewing tower crane which is utilized in construction nowadays is the horizontal boom. These eye-catching structures are seen all around the globe.
How to Erect a Tower Crane
Tower cranes are normally used on construction sites to move materials from low to high areas and vice versa. They are used for high-rise structures in places where a wheel-mounted crane is not big enough to carry out the work. Just trained experts should be the ones to build a tower crane. In order to keep everybody safe, this job must be carried out by professionals. There is a high possibility of collapse, which could lead to extensive loss and damage if you try to raise it on your own with hardly any experience.
When preparing to erect the crane, an excavator has to dig out a pit big enough for the base of the crane. After that, this hole is filled with concrete. Steel anchors are set into the concrete, and next, the first part of the crane's mast is connected. The concrete must cure for 24 hours.
The first mast part could be bolted to the anchors, once the base has finally set. By utilizing your spirit level, one could make sure that the mast is vertical. Afterward, fix another section of the mast by initially utilizing bolts and keep repeating this process until your desired height has been attained. It will be vital to utilize a telescopic boom or a scissor lift in order to do this step.
