Work Machine Elevating Cab Position Detection for Travel Shaking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work machines with elevating cabs experience shaking during traveling, which affects the fatigue life of the structural components and operator comfort.
Innovation Solution
A work machine equipped with an elevating cab that includes a detection system to determine the cab's position and controls the travel speed to low speed when the cab is elevated above a predetermined height, using a control system to stabilize the cab and reduce shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the work machine travels at high speed with the elevating cab raised, then productivity is improved, but shaking increases which reduces structural reliability and operator comfort
Solution Approach 1:
The system dynamically adjusts travel speed based on the elevating cab's position. When the cab is raised above a predetermined height, the control part automatically limits travel speed to low speed to reduce shaking and protect structural components. This dynamic speed adjustment resolves the contradiction by adapting the travel conditions to the current structural state.
2Productivity
If the work machine travels at high speed with the elevating cab raised, then productivity is improved, but shaking increases which reduces operator comfort
Solution Approach 1:
The detection part continuously monitors the position of the elevating cab, and the control part uses this feedback information to automatically adjust travel speed. When the cab position exceeds the predetermined height, the system responds by limiting speed to reduce shaking, thereby protecting operator comfort while maintaining productivity when conditions allow.
3Ease of operation
If the elevating cab is raised to high position, then operational visibility and workspace access are improved, but the structure becomes more susceptible to shaking damage during traveling
Solution Approach 1:
The system provides dynamic protection by automatically adjusting travel speed based on real-time detection of cab position. This allows the cab to be raised to high positions for improved visibility and workspace access, while the control system simultaneously protects structural components by limiting travel speed during moving, preventing excessive shaking damage.

AI summary
A work machine includes an elevating cab, a detection part configured to detect the position of the elevating cab, and a control part configured to maintain a travel speed at low speed when a traveling operation is performed while the position of the elevating cab detected by the detection part is higher than a predetermined height.
