Looking into the skyline of a larger 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 utilized to balance the crane's load. There are numerous models of tower crane types. These lattice-woven structures are available for special applications. Some common types comprise top-slewing, self-erecting and bottom-slewing models. Slewing means turning around a fixed point. The main type of top-slewing tower crane that is used in construction these days is the horizontal boom. These eye-catching structures are seen throughout the globe.
How to Erect a Tower Crane
A tower crane is common on construction locations to move materials from low to high areas and vice versa. These machinery are utilized in settings where a wheel-mounted crane is not large enough to carry out the work, like on high-rise structures. Only skilled experts must be the ones to erect a tower crane. To be able to keep everyone safe, this job must be done by experts. There is a high chance of collapse, that could result in extensive damage and loss if you try to built it yourself with hardly any experience.
In preparation of erecting the crane, an excavator is utilized to dig out a big pit that is used 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 attached. The concrete should cure for 24 hours.
The first mast section can be bolted to the anchors, once the base has finally set. By using your spirit level, one can make sure 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 vital to utilize a scissor lift or a telescoping boom in order to carry out this step.
