Industrial Truck Load Carrier with Integrated Tilting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial truck load carriers often have large sizes and unfavorable weight distributions, limiting load capacity and visibility for operators, especially when equipped with tilting and side-shifting mechanisms, which complicates maneuvering in narrow spaces and reduces maximum payload.
Innovation Solution
A compact load carrier design with a rotatable and sliding cylinder housing integrated into the upper receptacle, allowing horizontal displacement and vertical tilting, reduces weight and assembly effort while maximizing driver visibility and payload capacity by minimizing obstruction and weight distribution issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate fork carriage with tilting mechanism is attached to the lifting carriage, then the load handling device can be tilted forward or backward, but the industrial truck has a large extension in front of the mast leading to unfavorable weight distribution and limited load capacity
Solution Approach 1:
The patent combines the tilting mechanism and fork carriage into an integrated load carrier unit that rotates about a vertical axis at the mast location. This merging eliminates the need for a separate extended fork carriage while maintaining the tilting function, thereby improving weight distribution and load capacity without sacrificing operational capability.
Solution Approach 2:
The invention introduces rotation about a vertical axis (adding a rotational degree of freedom in the vertical plane) to achieve tilting functionality. This dimensional change allows the load carrier to tilt forward or backward by rotating in place, eliminating the need for horizontal extension and improving weight distribution.
2Adaptability or versatility
If the fork carriage is extended in front of the mast to enable tilting, then the load handling device can be positioned for low ground clearance loads, but the device has a large size that is disadvantageous in narrow areas
Solution Approach 1:
The patent merges the tilting function into the compact load carrier body by implementing rotation about a vertical axis at the mast. This eliminates the need for an extended fork carriage structure, maintaining adaptability for low ground clearance loads while significantly reducing the overall device volume for maneuvering in narrow spaces.
Solution Approach 2:
The invention achieves tilting capability through rotation about a vertical axis rather than horizontal extension. This dimensional change allows the load carrier to achieve the same positioning capability in a compact form factor, reducing the device volume while maintaining versatility.
3Ease of operation
If traditional fork carriage designs are used with separate tilting mechanisms, then the load carrier can be tilted, but the viewing window for the driver is restricted
Solution Approach 1:
The patent merges the tilting mechanism into the load carrier body itself, with the rotation axis located at the mast. This integration eliminates the need for separate external tilting mechanisms that would obstruct the driver's view, maintaining full load tilting functionality while preserving a clear viewing window.
4Adaptability or versatility
If multiple separate components are used for load carrier, tilting mechanism, and fork carriage, then each function can be optimized, but the assembly effort and number of components increases
Solution Approach 1:
The patent combines the load carrier, tilting mechanism, and fork carriage into a single integrated unit that rotates about a vertical axis at the mast. This merging maintains all necessary functional capabilities while significantly reducing the number of separate components and simplifying assembly procedures.
Solution Approach 2:
The integrated load carrier serves multiple functions simultaneously: it carries loads, provides tilting capability through rotation, and acts as the fork carriage structure. This multi-functionality eliminates the need for separate specialized components, reducing device complexity while maintaining versatility.
