Dual Hydraulic Tank Layout for Compact Loader Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current loaders are often too large to maneuver and access confined spaces due to their large footprint, and their single hydraulic tank configuration complicates fluid distribution and maintenance access.
Innovation Solution
A compact work machine with a frame that houses various components, featuring a dual hydraulic tank system where a primary tank is centrally positioned and a secondary tank is positioned rearward and above, allowing for efficient hydraulic fluid distribution and improved maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single hydraulic tank is used, then the hydraulic system structure is simple, but it is difficult to position the tank to simultaneously supply hydraulic fluid efficiently and provide access for maintenance
Solution Approach 1:
The hydraulic tank system is segmented into a primary tank and a secondary tank. The primary tank is positioned centrally to supply hydraulic fluid efficiently to the hydraulic pump, while the secondary tank is positioned rearward and above to provide accessible fluid storage and refilling. This segmentation resolves the contradiction by separating the functional requirements of hydraulic supply and maintenance accessibility into different spatial locations.
2Length of moving object
If the loader size is reduced for better maneuverability, then the footprint is smaller, but the hydraulic system may not have sufficient space for proper tank positioning and fluid distribution
Solution Approach 1:
The secondary tank is positioned in the vertical dimension (above the primary tank) rather than only in the horizontal plane. This three-dimensional arrangement allows the compact loader to accommodate both tanks within a reduced footprint while maintaining efficient hydraulic fluid distribution. The vertical positioning of the secondary tank utilizes unused vertical space, resolving the contradiction between compact size and hydraulic system functionality.

Function Achieved in This Case
The compact design enhances maneuverability and accessibility in confined spaces, while the dual hydraulic tank system optimizes hydraulic fluid supply and maintenance accessibility, improving overall operational efficiency.
Implementation Method 1
The secondary tank is spaced apart from, rearwardly and above, the primary tank

AI summary
A work machine comprising a frame configured to house a plurality of components of the work machine. The frame extends longitudinally from a rear end to a front end. The work machine further comprises a hydraulic system configured to provide hydraulic power to one or more hydraulically-powered components of the work machine. The hydraulic system includes a primary tank configured to hold hydraulic fluid, a hydraulic pump or a hydrostatic transmission configured to provide hydraulic fluid from the primary tank to the one or more hydraulically-powered components, and a secondary tank configured to hold hydraulic fluid and in fluid communication with the primary tank. The secondary tank is spaced apart from, rearwardly and above, the primary tank.
