Looking into the skyline of a bigger city, one would see tower cranes constructed near tall buildings and skyscrapers. These big structures are described as a central shaft that is counterweighted with a long boom used to balance the crane's load. There are numerous kinds of tower crane types. These lattice-woven structures are available for special uses. Several popular types consist of self-erecting, bottom-slewing and top-slewing units. 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 seen all over the globe.
How to Erect a Tower Crane
A tower crane is common on construction sites to move supplies from high to low places and vice versa. These machines are utilized in environments where a wheel-mounted crane is not big enough to carry out the work, like on high-rise structures. Just trained experts must be the ones to erect a tower crane. In order to keep everyone safe, this task needs to be done by professionals. There is a high risk of collapse, which could cause extensive loss and damage 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. After that, this hole is filled with concrete. Steel anchors are set into the concrete, and then, the first section of the crane's mast is connected. The concrete must cure for 24 hours.
The first mast part could be bolted to the anchors, when the base has finally set. By utilizing your spirit level, one could make certain that the mast is vertical. 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 to be able to perform this step.
