Self-Assembling Guy Supports for Mobile Crane Telescopic Boom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling and disassembling telescopic boom guy supports on mobile cranes are complex and time-consuming, requiring multiple steps and external assistance for larger cranes with longer booms, which complicates transport and deployment.
Innovation Solution
A guying system with individually mountable guy supports and an integrated assembly device that allows for self-assembly and storage, featuring adjustable frame parts that can change width for transport and assembly, enabling the crane to position and secure the supports without external help, thus simplifying the process and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If guy wires are mounted as a single unit on the telescopic boom, then assembly is simplified, but weight increases and lifting capacity is reduced
Solution Approach 1:
The bracing system is divided into separate guy wire units that can be mounted individually on the telescopic boom, rather than as a single integrated assembly. This segmentation reduces the weight that must be lifted and mounted, while each unit can be independently positioned and secured to the boom.
2Ease of operation
If the mounting device width is increased to accommodate telescopic boom assembly, then assembly is enabled, but transport width is exceeded
Solution Approach 1:
The mounting device incorporates adjustable frame parts that can change their relative position to alter the overall width. During transport, the frame parts are positioned to minimize width and comply with road transport regulations. During assembly, the frame parts are adjusted to provide sufficient width for the telescopic boom to be lowered between the guy wires.
3Manufacturing precision
If multiple individual lifts are used to position guy wires, then precise positioning is achieved, but time and complexity increase
Solution Approach 1:
The mounting device integrates the positioning and support functions into a single unit that can be lifted and positioned in one operation. The adjustable frame parts allow the device to accommodate the telescopic boom while maintaining precise positioning of the guy wires, eliminating the need for multiple separate lifting operations.
4Ease of operation
If the mounting device remains attached to the mobile crane, then storage is simplified, but weight and complexity increase
Solution Approach 1:
The mounting device is designed to serve multiple functions: it acts as a transport platform for the guy wires, a positioning device during assembly, and a storage structure during operation. The adjustable frame parts can be configured for different operations, and the device can be detached when not in use, reducing overall complexity while maintaining versatility.
