Forklift Display Integrating Truck and Rack Load Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for informing operating personnel about the maximum permissible load capacity of industrial trucks, particularly forklifts, often lead to confusion due to multiple stickers and incorrect readings, which can result in personal injury and material damage, as they fail to account for both the truck's load capacity and the shelf's load capacity simultaneously.
Innovation Solution
An industrial truck equipped with a display and a control unit that determines and displays the minimum of the truck's maximum permissible load capacity and the shelf's maximum permissible load capacity, ensuring accurate and safe loading and unloading by integrating with load handling devices and shelf transponders to provide precise information on lifting heights and load center distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple information signs are attached to the industrial truck to indicate different load capacities, then the information completeness is improved, but the confusion and incorrect reading among operating personnel increases
Solution Approach 1:
The patent combines multiple information signs into a single integrated display device that shows both the truck's maximum permissible load capacity and the shelf's maximum permissible load capacity together. This merging eliminates the confusion caused by multiple separate stickers while maintaining complete information about both load limits.
Solution Approach 2:
The display device acts as an intermediary between the control unit and the operating personnel. It receives data from the control unit about both truck and shelf load capacities and presents this information in a clear, unified format that is easy to understand and prevents misinterpretation.
2Device complexity
If the control unit is integrated into the industrial truck, then the system complexity is reduced, but the flexibility and adaptability to different trucks decreases
Solution Approach 1:
The control unit is designed with universal functionality to work with different types of industrial trucks and various load handling devices. It can identify different truck types, retrieve appropriate load capacity data, and communicate with different shelf systems, making it adaptable across multiple applications without requiring separate units for each truck type.

AI summary
The invention relates to a forklift truck with a display, a drive unit and a load handling device, wherein the display is in contact with a control unit, wherein the control unit is configured to identify a rack to be loaded or unloaded and to determine its maximum permissible rack load capacity mRT and to determine the maximum permissible load capacity mFT of the forklift truck and to determine the minimum from the determined values and to transmit the minimum as the maximum permissible load capacity of the forklift truck as a function of the maximum permissible rack load capacity to the display, which is arranged in the field of vision of the operating personnel, for visualization purposes.
