Looking into the skyline of a bigger city, one would find tower cranes built beside skyscrapers and tall buildings. These large structures are described as a central shaft which 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 special applications. Some common kinds 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 utilized in construction nowadays is the horizontal boom. These eye-catching structures are found all over the globe.
How to Erect a Tower Crane
A tower crane is common on construction locations to transport supplies from high to low areas and vice versa. These machinery are used in environments where a wheel-mounted crane is not large enough to finish out the work, like on high-rise structures. Only skilled professionals should be the ones to erect a tower crane. In order to keep everybody safe, this task must be done by experts. There is a high possibility of collapse, which could 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 utilized to dig out a big pit which is utilized for the base of the crane. The hole is then 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.
When the base has set, connect the first mast section firmly to the anchors utilizing the right bolts. Make sure that the mast is vertical by using your spirit level. Afterward, fix another section of the mast by initially using bolts and keep repeating this method until your desired height has been attained. It would be necessary to use a scissor lift or a telescoping boom to be able to carry out this step.
