Summary
This study introduces a computer-driven technique to analyze lifting forces in complex, non-homogeneous load situations. The dynamic algorithm accurately assesses lifting posture and load balance, aligning with established safety guidelines.
Area of Science:
- Biomechanics
- Occupational Safety and Health
- Ergonomics
Background:
- Assessing lifting forces in non-homogeneous load situations presents challenges.
- Existing methods may not fully capture dynamic and unconstrained lifting postures.
- Accurate analysis is crucial for preventing workplace injuries.
Purpose of the Study:
- To develop and test a computer-driven technique for analyzing lifting forces.
- To evaluate unconstrained lifting posture and non-homogeneous load content.
- To provide a tool for industrial and safety analysts.
Main Methods:
- A dynamic algorithm was developed to analyze lifting forces.
- Three-dimensional coordinates of body postures were used as input.
- Data was obtained from pictures taken at a worksite.
Main Results:
- The technique showed a good match with pre-study assumptions for balanced and non-balanced lifting.
- Results correlated well with symmetrical lifting tasks and National Institute for Occupational Health (NIOSH) guidelines.
- The computer-driven analysis demonstrated effectiveness in real-world scenarios.
Conclusions:
- The developed technique accurately analyzes lifting forces in non-homogeneous load situations.
- It offers a reliable method for evaluating lifting postures and load dynamics.
- This approach is suitable for industrial and safety analysts to improve workplace safety.
