When looking out over any bigger city skyline, you are likely to find tower cranes erected beside skyscrapers and tall buildings. These huge, interesting structures are usually described as a central shaft which has counterweights and a long boom used 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 units. Slewing means turning around a fixed point. The main kind of top-slewing tower crane that is used in construction nowadays is the horizontal boom. These eye-catching structures are found throughout the globe.
How to Erect a Tower Crane
Tower cranes are normally utilized on construction sites to move supplies from high to low areas and vice versa. They are used for high-rise structures in places where a wheel-mounted crane is not large enough to finish out the work. Only trained professionals should be the ones to erect a tower crane. To be able to keep everyone safe, this task should be carried out by experts. There is a high chance of collapse, which can result in extensive loss and damage if you try to raise it yourself with hardly any experience.
In preparation of building the crane, an excavator is used to dig out a large pit which is used for the cranes base. 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 part could be bolted to the anchors, when the base has finally set. By using your spirit level, one could ensure that the mast is vertical. Next, fix another section of the mast by initially utilizing bolts and keep repeating this method until your desired height has been attained. It would be vital to utilize a telescopic boom or a scissor lift to be able to do this step.
