Looking into the skyline of a larger city, one would see tower cranes built near tall buildings and skyscrapers. 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 numerous models of tower crane types. These lattice-woven structures are available for particular applications. Some popular types include bottom-slewing, top-slewing and self-erecting units. Slewing means 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 throughout the world.
How to Build a Tower Crane
A tower crane is common on construction locations to move materials from low to high areas and vice versa. These machines are used in environments where a wheel-mounted crane is not big enough to carry out the work, like on high-rise structures. Only trained experts must be the ones to erect a tower crane. To be able to keep everybody safe, this job must be carried out by professionals. There is a high possibility of collapse, that can lead to extensive loss and damage if you try to raise it yourself with hardly any experience.
When preparing to erect the crane, an excavator has to dig out a pit large enough for the base of the crane. Then, this hole is filled with concrete. Steel anchors are set into the concrete, and afterward, the first part of the crane's mast is attached. The concrete should cure for 24 hours.
The first mast part could be bolted to the anchors, once the base has finally set. By using your spirit level, one can ensure that the mast is vertical. Next, 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 necessary to use a telescopic boom or a scissor lift to be able to carry out this step.
