Loader Lift Link Hydraulic Pipe Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loader work machines have exposed hydraulic pipe arrangements that are prone to damage and detract from the appearance, requiring numerous clamps for fixation.
Innovation Solution
The hydraulic pipe arrangement is routed through a hose accommodation space formed between the link inner and outer walls of the lift links, reducing exposure and allowing secure, clamp-reduced fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hydraulic pipe arrangement is disposed in an exposed manner on the internal side of the lift link, then the hydraulic connection is established, but the hydraulic pipe arrangement is likely to be damaged and the appearance is deteriorated
Solution Approach 1:
The hydraulic pipe arrangement is routed through the hose accommodation space formed between the inner wall and outer wall of the lift link, effectively nesting the pipe within the structural framework. This protects the hydraulic components from external damage while integrating them into the existing machine architecture, eliminating the need for separate protective coverings.
Solution Approach 2:
The lift link structure itself serves as an intermediary protective element between the hydraulic pipe arrangement and the external environment. By utilizing the space between the inner and outer walls of the lift link, the design provides inherent protection without requiring additional protective components.
2Ease of operation
If the hydraulic pipe arrangement is exposed outside, then the hydraulic connection is accessible, but the appearance of the rear portion is deteriorated
Solution Approach 1:
The hydraulic pipe arrangement is nested within the hose accommodation space of the lift link structure, which is positioned on the rear portion of the machine. This integration conceals the hydraulic components from external view while maintaining their functional accessibility, thereby improving the appearance without compromising operational access.
3Adaptability or versatility
If nothing restricts the movement of the hydraulic pipe arrangement, then the pipe can move freely, but numerous clamps are required for fixing the hydraulic pipe arrangement
Solution Approach 1:
By nesting the hydraulic pipe arrangement within the hose accommodation space formed by the lift link's inner and outer walls, the design provides inherent structural restriction on pipe movement. This eliminates the need for numerous separate clamps, as the lift link structure itself serves as the fixation mechanism, reducing overall device complexity.
Solution Approach 2:
The lift link structure performs multiple functions: it provides mechanical support for the arm, contains the hydraulic pipe arrangement within its walls, and serves as the fixation mechanism through its inner and outer wall configuration. This multi-functionality eliminates the need for separate clamp components.

AI summary
A loader work machine is disclosed in which a base portion of each of right/left arms (77) is received by an arm support portion (164) of a first lift link (81) and pivotally supported by a first arm shaft (88), and a hydraulic pipe arrangement (167) connected to a hydraulic actuator (98) extend through an support frame (11) from inside to outside of its inner wall (12), and toward an arm (77). The base portion of the arm (77) is supported to the arm support portion (164) at a position adjacent a link outer wall (157) in a transverse direction so that a hose accommodation space (165) is formed between a link inner wall (156) and an internal side face of the base portion of the arm (77). The hydraulic pipe arrangement (167) runs frontward of the first arm shaft (88) and a first link shaft (85), and is disposed in the hose accommodation space (165).
