Telescopic Boom Coupling Region for Direct Guying Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle crane systems require intermediate storage of bracing apparatuses on the ground, which can be challenging on uneven surfaces and occupies valuable installation space, complicating the rigging and de-rigging process.
Innovation Solution
A vehicle crane with a coupling region on one of the inner boxes of the telescoping jib allows direct connection and transfer of the bracing apparatus without intermediate storage, enabling easier and safer rigging and de-rigging by eliminating the need for ground-based storage through the telescoping jib's own mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bracing apparatus is stored on the ground during rigging and de-rigging, then the assembly process can be performed, but the process becomes complicated and requires additional space which is problematic on uneven surfaces
Solution Approach 1:
The patent combines the storage function and the rigging/de-rigging function into a single integrated process. The telescoping jib serves both as the lifting mechanism and as the storage location for the bracing apparatus, eliminating the need for separate ground-based storage and simplifying the overall assembly process.
Solution Approach 2:
The telescoping jib is given multiple functions: it serves as the primary lifting mechanism, as the structural component being assembled, and as the storage location for the bracing apparatus during assembly. This multi-functionality eliminates the need for separate dedicated storage structures.
2Productivity
If the bracing apparatus is stored on the ground, then the assembly can proceed, but valuable installation space is occupied and ground stability is required
Solution Approach 1:
The bracing apparatus is stored within the telescoping jib structure itself, specifically in the space between the telescoping sections. This nesting approach allows storage without occupying additional ground space, as the storage location is integrated within the existing structural components.
3Ease of operation
If intermediate storage region is added to the vehicle crane, then bracing apparatus can be stored during assembly, but the installation space is reduced and cannot be used for other purposes
Solution Approach 1:
The telescoping jib provides a dynamic storage solution where the storage space is created by the extended configuration of the jib sections. When the jib is telescoped out, space is created between sections for storing the bracing apparatus, and this space disappears when the jib is retracted, making the space available for other purposes.

AI summary
A mobile crane comprising a telescopic boom which has a main casing with linearly moveable inner casings. Guying equipment can be added to the telescopic boom, where at least one securing region arranged on the main casing is provided for the fixing of the guying equipment. In order for the adding and removal of the guying equipment to and from from mobile crane to be carried out more easily and safely, at least one coupling region is arranged on one of the inner casings for adding and/or removing the guying equipment and which can be connected to the same. In this way, the guying equipment can be received directly from a transport unit by the at least partially extended telescopic boom, the guying equipment can be moved onto the main casing by retracting the telescopic boom and coupled to the same.
