Zielsetzung:
Wie es verwendet wird:
- Ergonomic guidelines, often presented in tables (like the Snook tables), that define the maximum forces that are acceptable for pushing and pulling tasks for different percentages of the population.
Vorteile
- Provides clear, evidence-based limits for pushing and pulling; Helps to design safer manual handling tasks.
Nachteile
- The values are for specific, controlled conditions and may not apply to all real-world scenarios.
Kategorien:
- Ergonomie, Risikomanagement
Am besten geeignet für:
- Designing manual material handling tasks, such as using carts or pallet jacks, to be safe for the majority of the workforce.
The application of Maximum Acceptable Pushing and Pulling Forces methodology is particularly valuable in settings like warehousing, manufacturing, and healthcare, where manual material handling is prevalent. Industries involved in logistics benefit significantly from these ergonomic guidelines, which offer a systematic approach to evaluating and improving workspace designs to accommodate a wide range of body types and strengths. For instance, when designing tasks that involve the use of trolleys or pallet jacks, embracing these ergonomic limits can reduce the risk of musculoskeletal injuries among workers. Participants in this methodology’s implementation typically include ergonomists, industrial engineers, safety personnel, and Humanressourcen staff who collaborate during the design phase of new processes or equipment. In practice, these guidelines can be used to develop training programs that educate employees on safe handling techniques, ensuring a lower incidence of work-related injuries. Companies may also use simulations or field tests to quantify how changes in equipment design or workplace layout affect the pushing and pulling forces experienced by workers, allowing for adjustments that enhance performance and safety. Engaging employees in feedback loops can further refine operational strategies, leading to innovations that prioritize human factors in design and elevate overall workplace health standards while also adhering to established regulatory requirements for safety.
Die wichtigsten Schritte dieser Methodik
- Identify the specific types of pushing and pulling tasks involved in the manual material handling.
- Determine the population percentile for which the design is intended (e.g., 5th, 50th, 95th percentile).
- Refer to established ergonomic guidelines, such as the Snook tables, for maximum force limits.
- Assess environmental conditions affecting force requirements (e.g., surface, slope, load stability).
- Evaluate the task biomechanics, focusing on posture and body mechanics during pushing and pulling.
- Implement design modifications based on identified forces and ergonomic principles.
- Test designs under realistic conditions with representative users to validate ergonomic compliance.
- Iterate on design adjustments based on feedback and performance metrics.
Profi-Tipps
- Utilize force measurement tools during the design phase to gather real-time data on pushing and pulling forces specific to your target user population.
- Incorporate adjustable handles or grips on equipment to accommodate a broader range of user heights and hand sizes, enhancing comfort and reducing strain.
- Implement iterative user testing with varying weights and conditions to assess the practicality and ergonomics of manual handling designs, using the Snook tables as a benchmark.
