Looking into the skyline of a larger city, one will find tower cranes erected 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 load of the crane. There are many kinds of tower crane types. These lattice-woven structures are available for particular applications. Some popular kinds comprise bottom-slewing, top-slewing and self-erecting units. Slewing refers to turning around a fixed point. The main kind of top-slewing tower crane which is used in construction nowadays is the horizontal boom. These eye-catching structures are seen all around the world.
How to Erect a Tower Crane
A tower crane is common on construction sites to move supplies from high to low areas and vice versa. These machinery are used in settings where a wheel-mounted crane is not big enough to finish out the work, like on high-rise structures. Only trained experts should be the ones to erect a tower crane. In order to keep everyone safe, this task has to be performed by professionals. There is a high risk of collapse, that can lead to extensive loss and damage if you try to built it on your own with hardly any experience.
In preparation of erecting the crane, an excavator is used to dig out a large 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 after that, the first section of the crane's mast is connected. The concrete is required to cure for 24 hours.
After the base has set, connect the first mast part firmly to the anchors using the proper bolts. Make certain that the mast is vertical by using your spirit level. After that, fix another section of the mast by first using bolts and keep repeating this process until your desired height has been attained. It would be necessary to employ a telescopic boom or a scissor lift in order to carry out this step.
