Compact Loader Track and Hinged Cab for Narrow Entry Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current work machines, such as loaders, are often too large to maneuver through narrow entryways, necessitating a compact design with reduced footprint for improved accessibility and maneuverability in confined spaces while maintaining functionality.
Innovation Solution
A compact loader design featuring a tracked drive assembly with endless tracks, torsion axles, and a hingedly connected operator cab, allowing for up-and-down movement of the track runs and cab positioning to facilitate navigation and maintenance, and utilizing electrical control lines to eliminate the need for hydraulic or mechanical linkages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the loader is designed with large size, then it can carry and operate heavy attachments, but it becomes difficult to maneuver and cannot pass through narrow entryways
Solution Approach 1:
The patent applies dynamics by making the operator cab hingedly connected to the frame, allowing it to swing between a horizontal operating position and a vertical stowed position. This dynamic configuration enables the loader to maintain full attachment carrying capability when the cab is in the horizontal position, while achieving improved maneuverability and reduced width profile when the cab is swung vertical to pass through narrow entryways
2Stability of the object's composition
If the loader is designed with large size, then it can provide stable operation, but it increases the footprint and reduces accessibility to confined spaces
Solution Approach 1:
The patent utilizes dynamics by implementing a hinged cab connection that allows the operator cab to swing between operating and stowed positions. When the cab is in the horizontal operating position, the loader maintains stable operation for work tasks. When the cab is swung vertical, the footprint is reduced, enabling access to confined spaces while preserving operational stability during actual work
3Strength
If traditional hydraulic linkages are used for cab control, then mechanical strength is sufficient, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent applies mechanics substitution by replacing traditional hydraulic linkages with an electrical control system. Electrical control lines are routed through conduits to actuate the cab swing mechanism, eliminating the need for complex hydraulic systems while maintaining sufficient mechanical strength for cab movement and reducing overall device complexity and maintenance requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compact loader achieves enhanced maneuverability and accessibility in confined spaces while maintaining operational efficiency and ease of maintenance through its innovative tracked drive and cab design.
Implementation Method 1
a torsion axle, with the track being entrained on the idler wheels and the one or more roller wheels. The idler wheels are supported relative to the loader frame and support the track adjacent the forward and aft track margins. The torsion axle shiftably supports a single one of the one or more roller wheels relative to the idler wheels and urges the single roller wheel into rolling engagement with the lower run, with the torsion axle permitting up-and-down movement of at least part of the lower run relative to the idler wheels.
