How to Erect a Tower Crane
Tower cranes are normally used on construction locations to transport 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 experts should be the ones to erect a tower crane. To be able to keep everyone safe, this job must be performed by professionals. There is a high risk of collapse, that could cause extensive damage and loss if you try to built it yourself with hardly any experience.
In preparation of building the crane, an excavator is utilized to dig out a big pit which is utilized for the base of the crane. The hole is then filled with concrete. Steel anchors are set into the concrete, and then, the first section of the crane's mast is attached. The concrete should cure for 24 hours.
The first mast section could be bolted to the anchors, once the base has finally set. By utilizing your spirit level, one could make sure that the mast is vertical. Afterwards, fix another part of the mast by initially utilizing bolts and keep repeating this method until your desired height has been attained. It would be necessary to utilize a telescopic boom or a scissor lift in order to perform this step.
