These lattice-woven structures are available for particular uses. Several popular kinds include bottom-slewing, top-slewing and self-erecting models. Slewing means turning around a fixed point. The main kind of top-slewing tower crane which is used in construction nowadays is the horizontal boom. These eye-catching structures are seen all around the world.
How to Erect a Tower Crane
A tower crane is common on construction sites to move supplies from low to high places and vice versa. These equipments are used in environments where a wheel-mounted crane is not large enough to finish out the work, like on high-rise structures. Just trained experts should be the ones to erect a tower crane. In order to keep everybody safe, this job should be done by professionals. There is a high risk of collapse, that could cause extensive loss and damage if you try to built it on your own with hardly any experience.
In preparation of erecting 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 next, the first part of the crane's mast is attached. The concrete is required to 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 could ensure that the mast is vertical. Next, fix another part of the mast by initially utilizing bolts and keep repeating this process until your desired height has been attained. It would be necessary to use a telescopic boom or a scissor lift to be able to do this step.
