Concrete Pump Boom Control Under Restricted Outrigger Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing truck-mounted concrete pumps face challenges in flexibility and complexity when operating on construction sites with limited space, as they require complex and unintuitive maneuvers to adjust the articulated boom's working area due to restricted outrigger extension, limiting their use on smaller sites.
Innovation Solution
A control device that identifies and simultaneously releases multiple working areas for the articulated boom based on detected outrigger positions, allowing intuitive movement between these areas without risking stability, and adjusts the boom's swivel angle according to the outrigger configuration, enabling the pump to operate on smaller sites by emulating a smaller reach category.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the outriggers are not fully extended due to confined site conditions, then the setup flexibility is improved, but the working area of the articulated boom must be restricted to prevent tipping
Solution Approach 1:
The control device dynamically adjusts the permitted working area of the articulated boom based on the actual extension positions of the outriggers detected by the sensor system. The control device calculates and releases appropriate working areas that adapt to the current support configuration, allowing the system to optimize between stability and working area coverage in real-time
2Reliability
If the working area is restricted to maintain stability, then the risk of tipping is reduced, but the operator cannot determine if the concreting area can be fully covered
Solution Approach 1:
The sensor system continuously detects the extension positions of the outriggers and provides feedback to the control device. The control device uses this feedback information to calculate and release the appropriate working area, ensuring the operator has complete information about the permitted operating zone while maintaining stability based on actual support conditions
3Device complexity
If a single working area is released based on outrigger positions, then the control is simplified, but complex maneuvers are required to reach the working area from the folded position
Solution Approach 1:
The control device divides the permitted working area into multiple segments or zones based on the outrigger configuration. This segmentation allows the articulated boom to be guided through a sequence of intermediate positions, breaking down complex maneuvers into simpler, more intuitive steps while maintaining stability throughout the movement

AI summary
A truck-mounted concrete pump includes a chassis, outriggers, a sensor system for detecting position of the outriggers, an articulated boom, and a control device. The articulated boom includes boom segments. The control device is configured to: control the articulated boom during execution of boom movements, identify and release a restricted working area of the articulated boom dependent on a detected support configuration of the outriggers, and simultaneously release at least one further working area of the articulated boom depending on the detected support configuration.
