How to Erect a Tower Crane
A tower crane is common on construction locations to move supplies from high to low places and vice versa. These equipments are used in environments where a wheel-mounted crane is not large enough to carry out the work, like on high-rise structures. Only skilled professionals should be the ones to erect a tower crane. To be able to keep everyone safe, this task has to be performed by professionals. There is a high chance of collapse, that can result in extensive loss and damage if you try to built it on your own with hardly any experience.
When preparing to erect the crane, an excavator needs to dig out a pit big enough for the crane's base. Then, this hole is filled with concrete. Steel anchors are set into the concrete, and next, the first part of the crane's mast is connected. The concrete should cure for 24 hours.
The first mast part can be bolted to the anchors, when the base has finally set. By using your spirit level, one can make sure that the mast is vertical. Afterward, fix another part of the mast by first using bolts and keep repeating this process until your desired height has been attained. It will be necessary to use a telescopic boom or a scissor lift to be able to do this step.
