Movable Tool Holder for Crane Base Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing arrangements of crane bases and tool holders face difficulties in coupling and decoupling tools due to spatial constraints, leading to increased user effort, risk of damage, and inefficiency in transporting cranes with loose cargo, as the tool holder is often integrated with the crane base, making it hard to access and position the crane arm for tool exchange.
Innovation Solution
A crane base and tool holder arrangement with a movement device that allows the tool holder to be positioned between transport and coupling positions relative to the crane base, reducing the required crane arm movement for tool coupling and decoupling, and enabling safer and more efficient tool handling and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the tool holder is integrated directly into the crane base to save space, then the space utilization is improved, but the accessibility for tool coupling and decoupling deteriorates
Solution Approach 1:
The tool holder is made movable relative to the crane base through a movement device, allowing it to dynamically change position between a retracted state (for space efficiency) and an extended state (for accessibility during tool coupling). This dynamic positioning resolves the contradiction by enabling both compact storage and easy operation at different times.
2Ease of operation
If the crane arm must be moved into a specific position for tool attachment, then the tool coupling is achieved, but the time consumption and operational complexity increase
Solution Approach 1:
The movement device acts as an intermediary mechanism between the crane base and the tool holder, enabling the tool holder to be positioned in an optimally accessible location independent of the crane arm position. This eliminates the need for complex crane arm positioning maneuvers, reducing time consumption and operational complexity while maintaining tool coupling capability.
3Area of stationary object
If the tool holder is positioned close to the crane base for space reasons, then the space efficiency is improved, but the risk of damage during operation increases
Solution Approach 1:
The system dynamically adjusts the distance between the tool holder and crane base based on operational requirements. During transport, the tool holder is retracted close to the crane base for space efficiency. During tool coupling operations, it is extended to a safer position that reduces the risk of damage to both the crane and the carrier vehicle.
