How to Erect a Tower Crane
Tower cranes are normally used on construction sites to move supplies from high to low places and vice versa. They are utilized for high-rise structures in places where a wheel-mounted crane is not large enough to carry out the work. Just trained professionals must be the ones to erect a tower crane. To be able to keep everybody safe, this job needs to be done by experts. There is a high chance of collapse, that can cause extensive damage and loss if you try to built it on your own with hardly any experience.
When preparing to build the crane, an excavator has to dig out a pit big enough for the crane's base. Next, this hole is filled with concrete. Steel anchors are set into the concrete, and after that, the first part 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 using your spirit level, one could ensure that the mast is vertical. After that, fix another part of the mast by first utilizing bolts and keep repeating this process until your desired height has been attained. It will be necessary to utilize a telescopic boom or a scissor lift in order to carry out this step.
