Looking into the skyline of a larger city, one will 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 used to balance the crane's load. There are numerous models of tower crane types. These lattice-woven structures are available for particular applications. Several popular types comprise 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 found throughout the globe.
How to Erect a Tower Crane
Tower cranes are commonly used on construction sites to move materials from high to low areas and vice versa. They are utilized for high-rise structures in places where a wheel-mounted crane is not big enough to carry out the work. Just trained professionals must be the ones to erect a tower crane. To be able to keep everyone safe, this job needs to be performed by experts. There is a high chance of collapse, which could result in extensive loss and damage if you try to raise it yourself with hardly any experience.
In preparation of erecting the crane, an excavator is utilized to dig out a big pit that is utilized for the cranes base. The hole is then filled with concrete. Steel anchors are set into the concrete, and next, the first section of the crane's mast is attached. The concrete must cure for 24 hours.
When the base has set, attach the first mast part securely to the anchors using the proper bolts. Make certain that the mast is vertical by utilizing your spirit level. After that, 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.
