Loader Roller Apparatus for Detached Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving apparatus for loaders on work vehicles do not efficiently facilitate the repositioning or relocation of the loader when detached from the vehicle, lacking effective ground engagement and support mechanisms.
Innovation Solution
The apparatus includes roller apparatus that can be fixedly, removably, or rotatably attached to the loader, with a use position closer to the ground and a storage position farther away, and a connector for attaching to another vehicle to reposition the loader, enhancing mobility and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the loader is detached from the work vehicle, then the loader can be relocated for different tasks, but the loader lacks effective ground engagement and support mechanisms for efficient repositioning
Solution Approach 1:
The roller apparatus is designed to be movable between a retracted position (when the loader is attached to the vehicle) and an extended position (when the loader is detached and needs to be moved). This dynamic configuration allows the system to adapt to different operational states, providing ground engagement only when needed for relocation, thus resolving the contradiction between relocation capability and repositioning efficiency.
2Ease of operation
If the roller apparatus is positioned near the ground surface, then ground engagement and support are provided for moving the loader, but the roller apparatus occupies space and may interfere with loader operations when not in use
Solution Approach 1:
The roller apparatus transitions between extended and retracted positions based on operational needs. When extended, it provides ground engagement for moving the loader; when retracted, it minimizes space occupation and interference with loader operations. This dynamic positioning resolves the contradiction between ground engagement capability and space occupation.
Solution Approach 2:
The roller apparatus is positioned in a third dimension (vertically above or below the loader) rather than occupying horizontal space alongside the loader. This vertical positioning allows the rollers to engage the ground when needed while minimizing interference with the loader's horizontal operating space, resolving the spatial contradiction.
3Reliability
If the roller apparatus is fixedly attached to the loader, then reliable ground engagement is achieved, but the roller apparatus cannot be adjusted or removed when not needed
Solution Approach 1:
The attachment mechanism allows the roller apparatus to be dynamically configured between fixedly attached (for reliable ground engagement during moving operations) and removable/retracted (when not needed). This dynamic attachment capability resolves the contradiction between reliability of ground engagement and adaptability for different operational states.

Function Achieved in This Case
Enables efficient repositioning and relocation of the loader by providing ground engagement and support through the roller apparatus and facilitating attachment to other vehicles for relocation tasks.
Implementation Method 1
The first roller apparatus is in contact with the ground surface in the use position

AI summary
A loader for a work vehicle includes a loader arm, a mast section rotatably connected to the loader arm, an implement removably attached to the loader arm, a first actuator connected between the loader arm and the mast, a second actuator connected between the loader arm and the implement, and a first roller apparatus having a use position and a storage position. The first roller apparatus is positioned nearer a ground surface in the use position than in the storage position. The first roller apparatus is in contact with the ground surface in the use position and spaced apart from the ground surface in the storage position.
