how do tower cranes come down

Tower cranes are an integral part of the construction industry. They are used to lift and move heavy materials like steel, concrete, and other construction materials. Once the construction project is completed, the tower cranes need to be dismantled and removed from the site. In this article, we will take a closer look at how tower cranes come down.

Preparations for Taking Down a Tower Crane

The process of dismantling and removing a tower crane can take several days and requires careful planning and preparation. A professional crane crew will begin by taking down any signage or fencing around the crane site. They will then perform a site survey to determine the best way to access the crane and the surrounding areas.The crew will then set up a rigging plan for disassembling the crane. This plan will include the lifting equipment, the methods for disassembling the structure, and the safety protocols to ensure the protection of everyone involved in the process.

Taking Down the Tower Crane

The disassembly of a tower crane is done in reverse order of how it was constructed. The crew will start with the top of the crane, working their way down to the base. They will begin by removing the machinery and the cab at the top of the crane.Next, the crew will begin disassembling the jib, which is the long horizontal arm that connects to the tower and supports the hook and load. They will remove the jib section by section until it is completely dismantled.The crew will then remove the tower sections one at a time until the entire structure is disassembled. The sections will be carefully lowered to the ground using a combination of rigging and winch systems.

Clean Up and Site Restoration

Once the tower crane is completely disassembled, the site will need to be restored to its original condition. This will include removing any debris left from the dismantling process and repairing any damage to the surrounding area.The assembled tower crane takes up a relatively small footprint, however, the area that is taken up by the disassembled crane components can be significant. Often, the crane company will have to lease a larger area of land for the disassembly process.The final step in the process is to remove any signage around the construction site and restore the site to pre-construction condition.

Conclusion

Taking down a tower crane is a complex process that requires careful preparation, planning, and execution. It is important to work with a professional crane crew that has experience in this type of work to ensure that the process is done safely and efficiently. By following the proper techniques for disassembly and cleaning up the site afterward, the construction project site can be transformed into its final state, with the tower crane no longer in sight.
