Vehicle Crane Jib Transfer Rocker for Automatic Bracing Rigging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle crane systems require complex and labor-intensive processes for rigging and de-rigging of bracing apparatuses, often necessitating precise orientation and additional structural configurations, which increases production costs and operational complexity, especially on uneven or unstable ground.
Innovation Solution
A jib system with integrated transfer rockers that allow the bracing apparatus to be automatically coupled and decoupled from the jib, enabling easy orientation and positioning without the need for extensive structural preparations, using transfer rockers and tensile elements to facilitate movement and attachment, allowing for self-rigging and de-rigging with minimal personnel and reduced material requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bracing apparatus is supported on the ground or on a storage region of the vehicle crane, then the rigging process can be performed, but the process becomes complex and labor-intensive requiring precise orientation and additional structural configurations
Solution Approach 1:
A transfer rocker is introduced as an intermediary component between the bracing apparatus and the jib. The transfer rocker includes a support element that can be supported on the ground or on a storage region of the vehicle crane, and a coupling element that couples the bracing apparatus to the jib. This intermediary simplifies the rigging process by eliminating the need for complex structural configurations while maintaining operational capability.
2Adaptability or versatility
If an additional storage region is formed on the vehicle crane, then the bracing apparatus can be stored, but the installation space required increases and cannot be used for other purposes
Solution Approach 1:
The storage region on the vehicle crane is designed to serve multiple functions. It can store the bracing apparatus when needed, but can also be used for other purposes when the bracing apparatus is not required. The transfer rocker enables the bracing apparatus to be positioned over the storage region without requiring dedicated space, allowing the storage region to maintain its versatility and not be permanently occupied by bracing apparatus storage infrastructure.
3Stability of the object's composition
If the bracing apparatus is oriented precisely opposite the direction of travel and in parallel with the longitudinal direction, then it can be stored on the storage region, but the ground support becomes difficult on uneven or unstable ground
Solution Approach 1:
The transfer rocker is designed with a support element that can adapt its orientation and position dynamically. Rather than requiring fixed precise orientation, the support element can adjust to uneven or unstable ground conditions while maintaining the coupling between the bracing apparatus and the jib. This dynamic capability allows the system to maintain stability without requiring precise initial orientation or stable ground conditions.

AI summary
A jib system for a vehicle crane having a telescopic jib and a bracing apparatus that can be coupled to the jib by its base frame, where the jib has a roller head and a lifting cable that is deflected via the roller head. Only minor structural measures and preparations are required for automatically rigging and de-rigging the vehicle crane, including by providing at least one transfer rocker that can be integrated in an articulated manner between the jib and the bracing apparatus. By the pivotable support of the transfer rocker on the jib, the base frame configured for coupling to the lifting cable can be displaced by a change in the length of the lifting cable that is effected in the coupled state on a circular path around its roller head from a set-down position of the bracing apparatus to a set-up position of the bracing apparatus and back.
