Looking into the skyline of a larger city, one would see tower cranes constructed near tall buildings and skyscrapers. These large structures are described as a central shaft which is counterweighted with a long boom used to balance the crane's load. There are many models of tower crane types. These lattice-woven structures are available for special applications. Several popular types consist of bottom-slewing, top-slewing and self-erecting models. Slewing means turning around a fixed point. The main type of top-slewing tower crane that is used in construction nowadays is the horizontal boom. These eye-catching structures are seen all over the world.
How to Erect a Tower Crane
Tower cranes are usually used on construction sites to move materials from low to high places and vice versa. They are utilized for high-rise structures in areas where a wheel-mounted crane is not big enough to carry out the work. Only trained experts should be the ones to build a tower crane. In order to keep everybody safe, this job must be carried out by experts. There is a high risk of collapse, that could cause extensive damage and loss if you try to built it yourself 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. Next, this hole is filled with concrete. Steel anchors are set into the concrete, and then, the first part of the crane's mast is connected. The concrete is required to cure for 24 hours.
When the base has set, attach the first mast part securely to the anchors using the right bolts. Ensure that the mast is vertical by using your spirit level. After that, fix another section of the mast by initially utilizing bolts and keep repeating this process until your desired height has been attained. It would be necessary to utilize a telescopic boom or a scissor lift in order to perform this step.
