Boom Lift Leveling Assemblies for Slope Traction and Stability
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 lift machine with a leveling system that includes pivotally coupled front and rear assemblies with actuators, allowing for semi-independent suspension and active control to maintain the chassis level relative to gravity, enhancing traction and operational capabilities on varied 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 limited, but stability and traction are insufficient
Solution Approach 1:
The leveling system divides the chassis into multiple independently controllable segments through front and rear assemblies that can adjust separately. Each assembly includes individual actuators that independently control the position of tractive elements, allowing localized adaptation to terrain variations while maintaining overall chassis stability.
Solution Approach 2:
The system employs dynamic actuators (hydraulic or electric) that continuously adjust the position of tractive elements in real-time based on terrain conditions. The semi-independent suspension allows the chassis to dynamically adapt to changing ground conditions, maintaining stability during operation on sloped or uneven surfaces.
2Reliability
If a leveling system with multiple actuators is added to maintain chassis level, then stability on sloped terrain is improved, but device complexity increases
Solution Approach 1:
The actuators serve multiple functions: they level the chassis, adjust tractive element position for terrain adaptation, and maintain operational stability. This multi-functionality reduces the need for separate systems and minimizes overall complexity despite the advanced capabilities provided.
3Adaptability or versatility
If tractive elements are positioned forward of the base, then traction on sloped terrain is enhanced, but structural complexity increases
Solution Approach 1:
The tractive elements are integrated within the assembly structure that is nested to the chassis. The assemblies contain the tractive elements and positioning mechanisms in a compact, space-efficient arrangement that minimizes structural complexity while achieving the forward positioning needed for enhanced traction.

AI summary
A boom lift includes a base having a first end and an opposing second end, a turntable coupled to the base, a boom coupled to the turntable, an assembly pivotably coupled to the first end of the base, and a first actuator coupled to the first end of the base and the assembly. The assembly includes a tractive element. The assembly extends from the base such that the tractive element is longitudinally offset from and spaced forward of the first end and the opposing second end of the base.
