Boom Lift Leveling Assemblies for Slope Stability and Traction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional boom lifts face challenges in maintaining stability and traction on uneven and sloped terrain, limiting their operational effectiveness and versatility.
Innovation Solution
A leveling system is introduced, comprising a front and rear assembly pivotally coupled to the base, with actuators controlling the pitch and roll of the lift device, allowing for semi-independent suspension and improved load distribution across tractive elements, enabling operation on larger slopes and varying terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional boom lifts operate on uneven and sloped terrain, then operational versatility is improved, but stability and traction deteriorate
Solution Approach 1:
The patent implements a dynamic leveling system with pivotably coupled front and rear assemblies that can independently adjust to terrain variations. The actuators continuously modify the pitch and roll angles of the base, allowing the lift device to adapt to changing terrain conditions while maintaining operational stability. This dynamic adjustment capability resolves the contradiction by enabling both terrain adaptability and stability simultaneously.
Solution Approach 2:
The system changes the operational parameters of the base by actively controlling pitch and roll angles through actuators. By adjusting these parameters in real-time based on terrain conditions, the system maintains optimal stability while operating on uneven and sloped surfaces, thus resolving the contradiction between versatility and stability.
2Adaptability or versatility
If traditional boom lifts operate on uneven and sloped terrain, then operational versatility is improved, but traction deteriorates
Solution Approach 1:
The dynamic leveling system with independently adjustable front and rear assemblies maintains continuous contact between tractive elements and the ground by actively compensating for terrain variations. This dynamic adaptation preserves traction forces while enabling operation on diverse terrains, resolving the contradiction between versatility and traction.
3Stability of the object's composition
If a leveling system with actuators is added to control pitch and roll, then stability is improved, but device complexity increases
Solution Approach 1:
The leveling system is segmented into independent front and rear assemblies, each with its own actuator and control capabilities. This segmentation allows for modular implementation and maintenance while achieving comprehensive stability control, thus resolving the contradiction between stability improvement and complexity increase.
4Force
If assemblies extend forward or rearward of the base, then traction is improved, but device complexity increases
Solution Approach 1:
The front and rear assemblies serve multiple functions: they provide traction enhancement through extended positioning, enable leveling control when pivotably coupled, and can be integrated with the base structure. This multi-functionality justifies the added complexity by delivering multiple benefits from the same structural elements, resolving the contradiction between traction improvement and device complexity.
