1. Ergonomic Evaluation of Mobile Work Platform Technology in Washington State Orchards Kit Galvin, Peter Johnson, Patrik Renyll, Richard A. Fenske 2011 National Symposium on Agriculture, Forestry and Fishing Health & Safety 29 June 2011 Boise, ID

2.  Cooperating orchards  Agricultural workers  Research team Maria Tchong-French Maria Negrete Pablo Palmández Anna Fretheim Contributers

3. Northwest Tree Fruit Industry  Activities require: high level of manual labor use of ladders  Labor is the greatest production cost

4. Northwest Tree Fruit Industry  Technology Roadmap decrease production costs increase orchard productivity  Major changes in tree fruit production orchard architecture assistive technologies  Minimize the health and safety impact Photo of fruiting wall

5. Goals Evaluate ergonomic stressors  Tasks pruning green fruit thinning  Equipment ladders self-propelled mobile platforms Recommendations for best practices

8. Pruning

9. Green Fruit Thinning

12. Exertion Heart rate Borg RPE

13. Example: pruner HR Time Heart Rate bpm

14. Upper Body Borg Crt10 scale Inclinometer

15. Next Steps  Complete data analysis  Validate Borg RPE and Borg CRT10 for hispanic men and women  Evaluate vacuum harvesting platform
