Skid Device for Loader Bucket Ground Protection and Material Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a device that can convert a loader bucket for multiple uses, including moving materials on the ground such as snow and long objects, while preventing ground damage, as existing solutions like bolt-on bucket-glide attachments are limited in versatility and effectiveness.
Innovation Solution
A skid device with a stepped underside and a mount bracket system that includes a wear member, retainer member, and fastener device, allowing the bucket to glide over surfaces without damaging them, and auxiliary members for carrying elongated objects wider than the bucket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a loader bucket is used to move material on the ground, then material handling capability is improved, but ground damage occurs due to the bucket's cutting edge contacting the surface
Solution Approach 1:
The patent introduces a skid device as an intermediary element between the loader bucket and the ground. This skid device has a curved lower surface that contacts the ground instead of the bucket's cutting edge, allowing the bucket to move material while the skid protects the ground from damage. The skid acts as a mediator that enables both material handling and ground protection simultaneously.
2Object-affected harmful factors
If bolt-on bucket-glide attachments are used to prevent ground damage, then ground protection is improved, but versatility is reduced as they are limited to specific uses
Solution Approach 1:
The skid device is designed with a universal mounting system that can be attached to various loader buckets and used for multiple purposes. The curved lower surface can accommodate different ground conditions, and the device can be used whether the bucket is moving material on the ground or carrying elongated objects. This multi-functional design resolves the contradiction between ground protection and versatility.
3Productivity
If the bucket cutting edge contacts the ground to move material, then material movement capability is improved, but the bucket edge wears down rapidly
Solution Approach 1:
The skid device serves as a protective intermediary that bears the contact with the ground, preventing direct interaction between the bucket cutting edge and the ground surface. This allows the bucket to maintain its material movement capability while the skid absorbs the wear and tear, significantly extending the service life of the bucket edge.
4Object-affected harmful factors
If a skid device with complex mounting system is used to protect ground, then ground protection is improved, but device complexity increases
Solution Approach 1:
The mounting system is segmented into distinct components: a mount bracket that attaches to the bucket, a retainer member that secures the skid, and a fastener device. This segmentation allows each component to perform its specific function independently, simplifying the overall design and making the assembly and disassembly processes more manageable despite the multi-functional requirements.

AI summary
A bucket assembly and a skid device and a method of manufacturing thereof has a ski-shaped member and is configured to be attachable to a front end portion of a loading bucket. Two or more skid devices can be attached to the front edge portion of the bucket to enable the bucket to move materials on the ground. Each skid device has a mounting bracket configured to be attached to the front edge portion of the bucket and has a main fastening device for securing it to the bucket and a secondary securing device comprising a retaining member that maintains the skid device on the bucket when the main fastening device becomes loose or fails. The retaining member prevents the skid device from falling off the bucket and acts as an alarm by making rattling noise. Each skid device also allows mounting of an auxiliary member that enables the bucket to carrying items longer than the width of the bucket, such as logs or posts.
