Loader Bucket Skid Device With Adjustable Slot Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skid devices for loader buckets, like the EDGE TAMER, face challenges in large applications due to tension securing methods, which are not practical and costly for wheel loaders, necessitating a simpler and more economical solution that preserves underlying surfaces during material displacement.
Innovation Solution
A skid device with a base plate featuring angled sections and a slot system for secure bolt-on attachment to loader buckets, allowing for adjustable mounting and inclusion of a wear member for improved gliding and longevity, enabling secure attachment without modifying the bucket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If tension securing method is used to attach skid device to loader bucket, then the skid device can be attached without modifying the bucket, but the securing method is not practical and economical for large applications like wheel loaders
Solution Approach 1:
The base plate is divided into multiple sections (first section with slot, second section angled upward, third section angled upward) that can be independently positioned and secured. This segmentation allows the skid device to be mounted securely to loader buckets of various sizes without requiring modification to the bucket, resolving the contradiction between easy manufacture and reliable attachment.
Solution Approach 2:
The slot in the first section provides adjustable positioning along the fore and aft direction, allowing the skid device to be dynamically positioned to achieve proper alignment and secure attachment. This dynamic adjustment capability enables reliable mounting across different loader bucket configurations without complex manufacturing.
2Ease of manufacture
If a skid device is designed with fixed dimensions, then manufacturing is simplified, but the device cannot accommodate loader buckets with or without accessories mounted
Solution Approach 1:
The slot extending in the fore and aft direction of the base plate enables adjustable positioning of the skid device along the loader bucket. This allows the same standardized base plate design to accommodate different mounting scenarios (with or without accessories) by simply repositioning the device along the slot, maintaining manufacturing simplicity while achieving versatility.
Solution Approach 2:
The base plate design with angled sections and slot positioning creates a universal mounting system that can attach to various loader bucket configurations. The same device structure serves multiple functions: mounting to buckets with accessories, mounting to buckets without accessories, and adjusting position fore and aft, all while maintaining a standardized manufacturing approach.
3Productivity
If the loader bucket has a long flat leading edge, then material can be easily lifted, but the leading edge cuts into the underlying ground and damages the surface
Solution Approach 1:
The skid device acts as an intermediary element between the loader bucket's leading edge and the ground surface. It provides a protective interface that prevents the bucket's flat edge from directly contacting and damaging the ground, while still allowing the bucket to perform its material lifting function effectively.
Solution Approach 2:
The skid device modifies only the local quality of the bucket's leading edge by adding a protective element, while leaving the rest of the bucket structure unchanged. This localized modification prevents ground damage at the contact point without affecting the overall material lifting capability of the bucket.

AI summary
A skid device and a loader bucket assembly includes the skid device, which include a ski-shaped base plate. The skid device is attachable to a front end of a loader bucket including a plurality of mounting holes for securing an accessory, such as an edge plate and a toothbar, to a bottom side of the loader bucket at a front side thereof, with a portion of the accessory extending forwardly of a front edge of the loader bucket when the accessory is mounted to the loader bucket. The skid device is also attachable to the loader bucket without the accessory mounted thereto. Two or more skid devices can be attached to the front end of the loader bucket to enable it to move materials on the ground.
