Sliding Bracket Assembly for Articulated Machine Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Articulated compactor machines face challenges in lifting operations due to the need for a center lifting point, which compromises articulation gap, operator visibility, and operator platform space, leading to reduced comfort and efficiency.
Innovation Solution
A bracket assembly with a sliding mechanism that allows the lifting point to extend when needed and retract for improved visibility and space, featuring a first rigid bracket and a slider bracket with guide rails and stopper plates for robust and reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a center lifting point is used for articulated compactor machines, then the machine can be lifted without excessive tilting, but the articulation gap is compromised and operator visibility is reduced
Solution Approach 1:
The bracket assembly incorporates a telescopic mechanism with movable segments that allow the bracket length to be adjusted dynamically. During lifting operations, the bracket extends to provide a center lifting point for stability. During normal operation, the bracket retracts to minimize obstruction of the articulation gap and improve operator visibility.
2Stability of the object's composition
If a center lifting point is used for articulated compactor machines, then the machine can be lifted without excessive tilting, but operator platform space is reduced
Solution Approach 1:
The telescopic bracket assembly retracts during normal operation to maximize operator platform space and only extends when lifting operations are required, thus maintaining machine stability during lifting without permanently reducing platform space.
3Area of stationary object
If a telescopic bracket assembly is used to improve visibility and space, then the bracket can retract during normal operation, but the complexity of the lifting mechanism increases
Solution Approach 1:
The bracket assembly is divided into multiple segments that can extend and retract relative to each other. This segmentation allows the bracket to change length while maintaining structural integrity and provides a relatively simple mechanism compared to other telescopic solutions.

AI summary
A bracket assembly (1) for lifting of an articulated machine (100) at a centre point (102), the bracket assembly comprising: a first rigid bracket (3) extending along a longitudinal axis (5) and including proximal end portion (7) for attaching the bracket assembly to the articulated machine and a distal end portion (9), and a slider bracket (11) including a through-hole (13) for engagement with a lifting hook (104), the slider bracket (11) is attached to the first rigid bracket (3) at the distal end (9) with a sliding mechanism (15) that is configured to allow for the slider bracket (11) to slide with respect to the first rigid bracket (3) along the longitudinal axis (5) between a default position and a lifting position, wherein in the lifting position the slider bracket (11) reaches further in a distal direction compared to in the default position.
