Foldable Tree-Cutting Boom Arm for Compact Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting and handling machines for trees require extensive space due to their expansive design, making them difficult to store and transport, and necessitate dedicated working machines for operation.
Innovation Solution
The apparatus features a pivotable boom arm with a rotatable crane pillar, a first boom, and a second boom, allowing for expansive movements while also being compactly configured for storage and transport. The gripping or cutting head is pivotable about a third axis, enabling it to be folded into a storage position, allowing the booms to be arranged in a space-saving manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the boom arm is designed to perform expansive movements for cutting and handling trees, then the radius of action is improved, but the space required for storage and transport increases
Solution Approach 1:
The boom arm is divided into multiple segments (first boom, second boom, third boom) that can be independently articulated and folded relative to each other. This segmentation allows the structure to maintain its full extended length for work operations while being able to collapse into a compact configuration for transport and storage, effectively resolving the contradiction between operational reach and storage footprint.
Solution Approach 2:
The booms are designed to nest within each other when folded, with the second boom able to position under the first boom and the third boom able to position under the second boom. This nesting arrangement maximizes space efficiency during storage and transport while preserving the full extended length for cutting and handling operations, directly addressing the space contradiction.
2Ease of operation
If the gripping or cutting head is positioned in front of the second end region for cutting operations, then the working capability is improved, but the space required for storage increases
Solution Approach 1:
The gripping or cutting head is mounted on a pivoting mechanism that allows it to dynamically change its position between a forward working position for cutting operations and a folded-back storage position. This dynamic positioning capability enables the system to optimize for working capability during operations and minimize storage space when not in use, resolving the contradiction between operational ease and storage requirements.
Solution Approach 2:
The gripping or cutting head can pivot not only forward and backward but also laterally to the side of the boom structure. This multi-dimensional movement capability allows the head to be positioned out of the way during storage while maintaining full access to cutting positions during operation, effectively resolving the space versus operability contradiction through spatial reconfiguration.

AI summary
An apparatus for cutting and/or handling material to be cut, in particular trees, having a pivotable boom arm to which a gripping or cutting head is attached. The boom arm includes a rotatable crane pillar, a first boom pivotably mounted on the rotatable crane pillar about a first pivot axis, a second boom pivotably mounted on the first boom about a second pivot axis. The gripping or cutting head is pivotably mounted on the second boom about a third pivot axis, and a controllable pivoting device is provided, by which the gripping or cutting head can be pivoted about the third pivot axis from a folded-out working position, in which the gripping or cutting head is mounted in front of the second boom, into a folded-in storage position, in which the gripping or cutting head is arranged to the side of the second boom.
