  1. 1. Orchard picking platform standards Keith Batten July 2009 Keith Batten & Assoc 1
  2. 2. Orchard picking platform standards • Horticulture Australian Limited (HAL) sponsored a cross-industry project to negotiate standards for orchard picking platforms starting late 2005 • New Zealand joined with Australia to add more weight to the task Keith Batten & Assoc 2
  3. 3. Orchard picking platform standards Progress to date: The operating standard AS 2550.10 has been published- • Improvements to maintenance requirements • Rules for fall-arrest systems Keith Batten & Assoc 3
  4. 4. Orchard picking platform standards Progress to date: The operating standard AS 2550.10 has been published- • Improvements to maintenance requirements • Rules for fall-arrest systems Design standard AS 1418.10 to be published 2009 • A separate section on Orchard platforms • A commentary section - the only published authority on orchard platforms Keith Batten & Assoc 4
  5. 5. Orchard picking platform standards A new international orchard standard ISO 16353-3 is currently in draft Why an international standard? Keith Batten & Assoc 5
  6. 6. Orchard picking platform standards A new international orchard standard ISO 16353-3 is currently in draft Why an international standard? • The international platform standards do not recognize orchard platforms and could be used to discredit a lone Australian/NZ standard in an OH&S prosecution or civil action. The international standard adds credibility due to the scrutiny by some 20 member nations Keith Batten & Assoc 6
  7. 7. Orchard picking platform standards A new international orchard standard ISO 16353-3 is currently in draft Why an international standard? • The international platform standards do not recognize orchard platforms and could be used to discredit a lone Australian/NZ standard in an OH&S prosecution or civil action. The international standard adds credibility due to the scrutiny by some 20 member nations • In time we expect ISO 16368 to supersede AS 1418.10 which would leave orchard platforms unrepresented Keith Batten & Assoc 7
  8. 8. Orchard picking platform standards A separate Orchard platform standard – We had to convince the Australian and International standards committees that orchard platforms are different. Keith Batten & Assoc 8
  9. 9. Orchard picking platform standards These electricity platforms are relatively sedentary once positioned. Controls are designed to prevent inadvertent movement – crush risk Keith Batten & Assoc 9
  10. 10. Orchard picking platform standards In contrast an avocado picker may pick 14 thousand pieces of fruit in a shift moving the platform some 4 thousand times. These controls are designed hands free so the operator can pick with both hands. The crush risk is less significant Keith Batten & Assoc 10
  11. 11. Keith Batten & Assoc 11
  12. 12. Orchard picking platform standards Other areas where orchard platform priorities differ from those of industrial application are set out in the standards and commentary attached to my paper: • Travel speed – orchard platforms are smaller and need to travel faster • Platform guard rails design to clear plant debris • Simultaneous use of controls • Enhanced stability requirements Keith Batten & Assoc 12
  13. 13. Orchard picking platform standards An issue for Manufacturers New regulations will require the platform stop once the stability limit has been reached. Keith Batten & Assoc 13
  14. 14. Orchard picking platform standards An issue for Manufacturers New regulations require the platform stop once the stability limit has been reached. The only way to improve stability and reset the controls is to lower the platform Keith Batten & Assoc 14
  15. 15. Orchard picking platform standards An issues for Manufacturers New regulations require the platform stop once the stability limit has been reached. The only way to improve stability and reset the controls is to lower the platform Lowering the platform can not reset the simple slope switches currently used A programmable slope switch will need to be developed to increase its switching angle as the platform is lowered. Keith Batten & Assoc 15
  16. 16. Orchard picking platform standards Gates - an issue for manufacturers and growers Keith Batten & Assoc 16
  17. 17. Orchard picking platform standards Gates - an issue for manufacturers and growers Most common accident in Australia - operators falling from platforms through an open gate Keith Batten & Assoc 17
  18. 18. Orchard picking platform standards Gates - an issue for manufacturers and growers Most common accident in Australia - operators falling from platforms through an open gate NZ does not have these accidents because their code of practice prohibits gates through the guard rail No problem for NZ operators Keith Batten & Assoc 18
  19. 19. Orchard picking platform standards Gates - an issue for manufacturers and growers Most common accident in Australia - operators falling from platforms through an open gate NZ does not have these accidents because their code of practice prohibits gates through the guard rail No problem for NZ operators AS 1418.10 draft - no gates through the guard rail Keith Batten & Assoc 19
  20. 20. Orchard picking platform standards Risk of overturning • Orchard platforms have been known to overturn when operating up and down a slope and then turn side on across the slope where they are less stable Keith Batten & Assoc 20
  21. 21. Orchard picking platform standards Risk of overturning • Orchard platforms have been known to overturn when operating up and down a slope and then turn side on across the slope where they are less stable • Fundamental issue – some platforms lack stability Keith Batten & Assoc 21
  22. 22. Orchard picking platform standards Orchards can be planted on serious slopes – 15 degrees here Keith Batten & Assoc 22
  23. 23. Orchard picking platform standards Single castor three wheelers are nimble and efficient for relatively flat areas– rated 5 to 7 degrees maximum Keith Batten & Assoc 23
  24. 24. Orchard picking platform standards Adding a walking beam 4-wheel drive to the single castor improves stability Keith Batten & Assoc 24
  25. 25. Orchard picking platform standards More stable again– dual castors added to the walking beam make a larger footprint Keith Batten & Assoc 25
  26. 26. Keith Batten & Assoc 26
  27. 27. Orchard picking platform standards Add tracks for greater traction and stability Keith Batten & Assoc 27
  28. 28. Orchard picking platform standards Can I leave you with this thought? Keith Batten & Assoc 28
  29. 29. Orchard picking platform standards Can I leave you with this thought? Standards are an agreement between industry and the regulator as to how the legislated requirements of the OH&S regulation can be met. Keith Batten & Assoc 29
  30. 30. Orchard picking platform standards Can I leave you with this thought? Standards are an agreement between industry and the regulator as to how the legislated requirements of the OH&S regulation can be met. Growers can remain part of the agreement by continuing an active involvement in developing standards ? Keith Batten & Assoc 30
