How to Erect a Tower Crane
A tower crane is common on construction sites to transport materials from low to high 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. In order to keep everybody safe, this task should be done by experts. There is a high risk of collapse, that can result in extensive loss and damage if you try to built it yourself with hardly any experience.
When preparing to build the crane, an excavator needs to dig out a pit big enough for the crane's base. After that, 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 should cure for 24 hours.
The first mast section can be bolted to the anchors, when the base has finally set. By utilizing your spirit level, one can make sure that the mast is vertical. Afterward, fix another part of the mast by initially 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 in order to carry out this step.
