Concrete Pump Truck Boom Multi-Plane Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional concrete pump trucks face limitations in extending concrete delivery distance while maintaining compliance with road transportation rules, as the number of boom sections is restricted by the dimensions of the truck, especially when the boom is in a folded state.
Innovation Solution
A unique folding mechanism for the boom sections, where the first to fifth sections are folded in a first direction, and the sixth and seventh sections are folded onto the fifth section in a reversed direction, allowing for maximum extension of the concrete delivery distance without increasing the overall dimensions of the truck when folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If more boom sections are added to extend concrete delivery distance, then the concrete delivery distance is improved, but the overall dimension of the pump truck increases when in folded state
Solution Approach 1:
The boom sections are arranged in two longitudinal planes instead of a single plane, allowing the boom to fold in multiple directions. This spatial arrangement enables more boom sections to be compacted into a smaller overall dimension when folded, while maintaining extended delivery distance when unfolded.
Solution Approach 2:
The boom is divided into multiple sections (first to seventh boom sections) that can independently fold relative to each other. This segmentation allows each section to be compacted separately, reducing the overall folded dimension while maintaining the ability to extend to long distances when needed.
2Length of moving object
If more boom sections are added to extend concrete delivery distance, then the concrete delivery distance is improved, but the device complexity increases
Solution Approach 1:
The sixth and seventh boom sections are combined and folded together onto the fifth boom section in a reversed direction, simplifying the folding pattern. This merging approach reduces the complexity of the folding mechanism while still achieving extended delivery distance through the multi-plane arrangement of boom sections.
Solution Approach 2:
The sixth and seventh boom sections are folded in a direction reversed to the first five sections. This inverted folding pattern creates a more compact folded configuration and simplifies the overall folding mechanism by using alternating fold directions rather than sequential folding in the same direction.

AI summary
The present invention provides a boom of concrete pump truck, which has a folded state and a unfolded state, wherein, the boom comprises at least six boom sections hinged in sequence, in said folded state, the first and second boom sections are in a first longitudinal plane, the fourth to the last boom sections are in a second longitudinal plane, the first longitudinal plane and the second longitudinal plane are parallel to each other and spaced; the third boom section extends between the first longitudinal plane and the second longitudinal plane, the first to the fifth boom sections can be folded in a first direction, and the sixth boom section can be folded onto the fifth boom section in a second direction reversed to the first direction. The present invention further provides a concrete pump truck comprising the above-said boom. With the technical solution described above, the concrete delivery distance can be extended as far as possible when the boom is in said unfolded state, and the overall dimension of the pump truck is not increased substantially when the boom is in said folded state.
