Crane Payload Simulation via Graphical Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current crane monitoring systems do not provide operators with clear information on maximum permitted payloads at positions other than the current discrete radius steps, making it difficult to plan and execute crane movements efficiently.
Innovation Solution
A monitoring and simulation system for cranes that includes input and output means to display the current and possible payloads graphically, allowing operators to visualize payload development and movements intuitively, using a calculation unit and model generation to simulate and calculate state developments, and display them as graphs or curves for easy understanding.

Engineering Contradiction Analysis
1Measurement precision
If discrete radius steps with stored payload values are used, then the payload information is complete and accurate, but the operator cannot obtain payload information for intermediate positions and must perform time-consuming calculations
Solution Approach 1:
The system pre-calculates and stores payload values for discrete radius steps in advance. This allows the operator to quickly access pre-computed data without performing real-time calculations, while still providing accurate payload information for planned positions.
Solution Approach 2:
A graphical display unit serves as an intermediary between the discrete payload data and the operator. It visually presents payload information for both current and intermediate positions, allowing operators to estimate payloads at any position without manual calculation.
2Reliability
If payload tables with discrete radius steps are displayed, then the payload data is structured and complete, but the operator must perform time-consuming evaluation to understand current and possible states
Solution Approach 1:
The system replaces manual table evaluation with an automated graphical display system. The calculation unit continuously computes and the display unit visually presents payload information, substituting the operator's manual analysis with automated computational and visual presentation systems.
Solution Approach 2:
The system transforms tabular payload data into a graphical dimension. By displaying payload information as visual curves and graphs showing payload development across different positions, the operator can immediately comprehend current and possible states without evaluating discrete table entries.
3Productivity
If maximum permitted payload is calculated only for current position, then the calculation is simple and fast, but the operator receives no information for other positions differing from current position
Solution Approach 1:
The system dynamically calculates and displays payload information for multiple positions simultaneously. Instead of a static single-position calculation, the calculation unit computes payload values for current and intermediate positions, and the graphical display updates in real-time as the crane moves or the operator plans movements.
Solution Approach 2:
The monitoring and simulation system serves multiple functions: it displays current payload, shows payload for intermediate positions, enables movement planning, and provides visual feedback for different crane states. This multi-functional approach replaces multiple separate tools with a single comprehensive system.
