Dual Knuckleboom Loader Single Operator Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional truck-mounted knuckleboom loaders are inefficient and redundant, requiring multiple operators and machinery, wasting time and resources, and limiting maneuverability in tight spaces due to their design and operational constraints.
Innovation Solution
A loader with two spaced knucklebooms mounted on a platform, allowing a single operator to control both from a centralized cab with 360° rotation, enabling efficient operation and task-specific use through customizable controls and integrated machinery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single truck-mounted knuckleboom loader is used, then the loader can perform cargo handling operations, but multiple operators and machinery are required, causing redundancy and resource waste
Solution Approach 1:
The patent combines two knuckleboom loaders into a single integrated platform, allowing one operator to control both booms simultaneously. This merging eliminates the need for separate operators and machinery, directly resolving the redundancy and resource waste issue while maintaining high productivity
Solution Approach 2:
The integrated platform provides multi-functionality by enabling a single operator to perform tasks that previously required multiple operators and separate loaders. The unified control system allows one person to manage both knucklebooms for various cargo handling operations, reducing the quantity of operators and machinery needed
2Adaptability or versatility
If a truck-mounted loader is relocated to a new location, then the loader can serve different areas, but the operator must leave the loader controls, drive the truck, and return, wasting time
Solution Approach 1:
The patent merges the loader controls with the truck cab by mounting the control station on the truck itself. This allows the operator to remain in the cab and control the knuckleboom loader without leaving, eliminating the time loss associated with relocating to different work areas while maintaining adaptability to serve multiple locations
3Ease of operation
If a truck-mounted loader operates in narrow areas, then cargo handling can be performed, but the long turning radius of the truck limits maneuverability and requires additional space
Solution Approach 1:
The patent segments the loader system from the truck by mounting the knuckleboom on a separate platform that can be positioned independently. This segmentation allows the loader to operate in confined spaces without being constrained by the truck's long turning radius, reducing the space required for maneuvering while maintaining ease of operation
Solution Approach 2:
The patent changes the operational dimension by allowing the knuckleboom to be positioned and operated independently from the truck's movement. The loader can extend and operate in areas that would be inaccessible to the truck itself, enabling operation in narrow areas without requiring the truck to maneuver in tight spaces
4Ease of operation
If the knuckleboom is positioned at one end of the truck, then the loader can be mounted on the platform, but the truck cab prevents full 360° operating range of motion
Solution Approach 1:
The patent segments the control system from the truck cab by providing remote controls that allow the operator to control the knuckleboom from any position around the truck. This segmentation eliminates the operational limitation imposed by the cab's position, enabling full 360° range of motion without increasing device complexity
Solution Approach 2:
The patent introduces remote controls as an intermediary between the operator and the knuckleboom. This intermediary allows the operator to control the loader from any position, including areas that would be blocked by the truck cab, thereby achieving full 360° operating range of motion without adding mechanical complexity

AI summary
The loader with multiple knucklebooms includes a platform, such as that associated with a standard semi trailer or a flatbed truck, as non-limiting examples, and at least a first knuckleboom and a second knuckleboom. The first knuckleboom is rotatably mounted on the platform and the second knuckleboom is mounted on the platform such that it is spaced apart from the first knuckleboom. The first knuckleboom includes a first boom and a first jib pivotally connected to the first boom. Similarly, the second knuckleboom includes a second boom and a second jib pivotally connected to the second boom. A proximal end of the first boom may be mounted on a turntable, and a cab associated with the platform may also be mounted on the turntable.
