These lattice-woven structures are available for special applications. Some popular types consist of bottom-slewing, top-slewing and self-erecting units. Slewing means turning around a fixed point. The main kind of top-slewing tower crane which is utilized in construction nowadays is the horizontal boom. These eye-catching structures are seen throughout the globe.
How to Erect a Tower Crane
Tower cranes are commonly utilized on construction sites to move materials from low to high places and vice versa. They are utilized for high-rise structures in areas where a wheel-mounted crane is not big enough to carry out the work. Just skilled professionals should be the ones to erect a tower crane. To be able to keep everybody safe, this task must be performed by experts. There is a high risk of collapse, which could result in extensive damage and loss if you try to raise it yourself with hardly any experience.
In preparation of erecting the crane, an excavator is utilized to dig out a large pit that is used for the base of the crane. The hole is then filled with concrete. Steel anchors are set into the concrete, and afterward, the first section of the crane's mast is connected. The concrete should cure for 24 hours.
After the base has set, attach the first mast part securely to the anchors utilizing the right bolts. Make certain that the mast is vertical by utilizing your spirit level. Next, fix another part of the mast by first using bolts and keep repeating this method 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.
