Skid Steer Loader Attachment for Confined Road Shouldering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road widening and shouldering attachments are large, costly, and require dump trucks, limiting their accessibility and usability in small areas and necessitating a more portable and versatile solution.
Innovation Solution
A compact, lightweight road widening and shouldering attachment for skid steer loaders, featuring a hopper, conveyor system, spreader system, hydraulic system, and universal mounting plate, powered by the skid steer loader's hydraulic system, allowing for easy transportation and operation in small areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a dump truck is used for road widening and shouldering, then material delivery capability is improved, but device size and cost increase
Solution Approach 1:
The attachment is divided into separate functional modules: a hopper for material storage, a conveyor system for material transport, and a spreader system for material distribution. This segmentation allows each component to be optimized independently and enables the attachment to be transported in standard-sized trailers while maintaining effective material delivery capability.
2Quantity of substance
If a dump truck is used for road widening and shouldering, then material delivery capability is improved, but cost increases
Solution Approach 1:
The attachment is designed to be universally compatible with various skid steer loaders through a standardized mounting plate that interfaces with common skid steer loader attachments. This multi-functionality allows the same attachment to be used across different equipment platforms, eliminating the need for expensive custom equipment and reducing overall project costs while maintaining effective material delivery capability.
3Power
If a dump truck is used for road widening and shouldering, then power availability is improved, but accessibility to small areas worsens
Solution Approach 1:
The attachment merges the material handling functions (hopper, conveyor, spreader) with the mobility of the skid steer loader. By combining these functions into a single integrated unit that can be easily attached and detached, the system gains both the power availability needed for material delivery and the compact size required for accessibility to small areas like bike paths, driveways, and cul-de-sacs.
4Area of moving object
If a compact attachment is used for skid steer loader, then accessibility to small areas is improved, but material delivery capability worsens
Solution Approach 1:
The conveyor system and spreader system are powered by the skid steer loader's hydraulic system, which provides sufficient power for material delivery despite the compact size of the attachment. This hydraulic power transmission enables the compact attachment to deliver materials effectively while maintaining accessibility to small working areas.

AI summary
An attachment for a skid steer loader for use in performing road widening and shouldering jobs in small areas such as bike paths, driveways and cul de sacs. The attachment includes a compact frame adapted to support a hopper, a conveyor system, a spreader system, a spreader system angular adjustment, a hydraulic system, at least one wheel, at least one contact roller, and a universal mounting plate. The hydraulic system receives its power from the hydraulic system of, for example, a skid steer.
