Integrated Guy Rod Fastening for Tower Crane Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of tower cranes with structural guying is complex and time-consuming due to the need for a separately mounted frame that encloses the tower element, which increases construction time and costs, especially in projects with rapid height growth like wind power plants.
Innovation Solution
The tower crane integrates guy rods directly to a fastening point within the tower element, eliminating the need for a separate enclosing frame, allowing for faster assembly and reducing the number of guy rods required, which minimizes assembly effort and slewing moments transferred to the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separately mounted frame is used to enclose the tower element for structure bracing, then the tower crane can be horizontally anchored to the structure, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent integrates the fastening points directly into the tower element structure itself, merging the previously separate frame and tower element into a unified system. The guy rods are fastened directly to the tower element at integrated fastening points, eliminating the need for a separate enclosing frame and reducing assembly complexity while maintaining anchoring stability
Solution Approach 2:
The patent extracts and eliminates the separate enclosing frame from the system by integrating its anchoring function directly into the tower element. The fastening points are built into the tower element structure, allowing the guy rods to be connected directly without requiring an additional frame structure
2Reliability
If a separately mounted frame is used for structure bracing, then the tower crane can be anchored to the structure, but the assembly time increases significantly
Solution Approach 1:
By merging the fastening points into the tower element structure itself, the patent eliminates the time-consuming process of assembling and attaching a separate frame. The integrated fastening points allow for direct connection of guy rods to the tower element, significantly reducing assembly time while maintaining structural anchoring reliability
Solution Approach 2:
The fastening points are pre-integrated into the tower element structure during manufacturing, rather than being assembled on-site. This preliminary action eliminates the need for complex on-site frame assembly and reduces the time required for structure bracing installation
3Reliability
If multiple guy rods are used to connect the tower element to the structure, then the anchoring stability is improved, but the assembly effort increases
Solution Approach 1:
The patent combines multiple guy rods into a single integrated bracing system that connects to a unified fastening point structure on the tower element. This merging approach maintains the stability benefits of multiple anchoring points while simplifying the assembly process through standardized, pre-integrated connection geometry
