Telescopic Loading Arm for ISO and Hooked Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loading arm assemblies for load-handling vehicles face difficulties in efficiently loading and unloading both ISO containers and roll-on/roll-off containers with hooks, especially on uneven terrain, requiring adapters and posing safety risks to operators due to the need for precise alignment and manual intervention.
Innovation Solution
A loading arm assembly with a crossbeam having corner grippers and a telescopic gripping hook on an auxiliary arm, allowing for pivoting about multiple axes to securely grip containers at various angles and positions, eliminating the need for adapters and enabling remote operation through sensor systems and automated control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a loading arm assembly uses corner grippers for ISO containers, then it can grip containers at upper corners, but it cannot effectively reach lower corners when containers sink into soft ground
Solution Approach 1:
The loading arm assembly incorporates a telescopic function that adds vertical dimensionality to the gripping mechanism. The telescopic arm can extend downward to reach lower corners of containers that have sunk into soft ground, transforming a two-dimensional horizontal gripping system into a three-dimensional system with vertical adjustment capability.
2Measurement precision
If a loading arm assembly requires precise alignment with containers, then it achieves accurate gripping, but it becomes difficult to operate on uneven terrain and poses safety risks to operators
Solution Approach 1:
The loading arm assembly features multiple telescopic sections that can dynamically adjust their length and position. This dynamic capability allows the system to compensate for misalignment on uneven terrain by extending or retracting arm sections, maintaining gripping accuracy without requiring precise initial alignment between the vehicle and container.
3Adaptability or versatility
If a loading arm assembly uses separate adapters for different container types, then it can specialize in gripping each type, but it increases device complexity and requires time-consuming attachment/detachment
Solution Approach 1:
The loading arm assembly integrates multiple gripping functions into a single universal system. The telescopic arm can configure itself to reach both upper and lower corners, eliminating the need for separate adapters for different container types. This multi-functional design allows the same arm structure to handle various container configurations without additional components.
Solution Approach 2:
The invention merges the functions of multiple specialized gripping mechanisms into one integrated telescopic arm system. By combining the capabilities of what would otherwise require separate adapters into a single unified structure with variable geometry, the system achieves container type compatibility while reducing overall device complexity.
4Adaptability or versatility
If a loading arm assembly requires manual intervention for adapter attachment, then it allows flexibility in configuration, but it exposes operators to danger and reduces productivity
Solution Approach 1:
The telescopic loading arm assembly is designed to automatically configure and adjust itself without requiring manual intervention. The system can self-adjust its arm extensions and gripping positions to accommodate different container types and terrain conditions, eliminating the need for operators to manually attach or configure adapters.

AI summary
A loading arm assembly for a load-handling vehicle has a main arm and an auxiliary arm. The loading arm assembly is configured for unloading and loading ISO containers and for unloading and loading transportation containers having a hook. The loading arm assembly is improved in that a crossbeam having two corner grippers and furthermore, separately therefrom, a telescopic gripping hook is disposed on the auxiliary arm.
