  1. Mechanisingvegetationoperations Jonathan Callis & Dr Neil Strong UAG Conference 12.07.2011

  2. Presentation outline • Safety and regulation • Mechanisation of operations - Inspection - Clearance - Processing - Maintenance • Questions 2

  3. Safety 3

  4. Regulator funding, required efficiencies CP5 4

  5. Benchmarking, watching, learning • We have been busy! • Other railways • Other linear asset owners • Other allied land based industries 5

  6. What we are trying to achieve http://www.bafu.admin.ch/publikationen/publikation/00612/index.html?lang=en 6

Strategy Summary - Extensive Zone Baled / Compacted Biomass Mechanical Whole Tree Clearance Processing Manual Timber Stump Treatment Motor Manual Manual Feed Clearance Processing Chipped Biomass Mechanised Remote Control Herbicide Application Heavy Maintenance LiDAR Inspection Data Manual Driven Machinery Herbicide Application Heavy Maintenance Visual Asset Database Inspection Data VideoInspection Data 8

  9. Inspections - Aerial 9

  10. Inspections - LiDAR Asset Surveying Diagram depicts classification of ‘woody vegetation’ encroaching within an infinite vertical space 5m fromthe outer ‘running rail’ 5m Classified points of encroachment Outer runningrail Ground returns 10

  11. LiDAR outputs 11

  12. Mechanising / Modularising Tree Work 12

  13. Tree Clearance - Road Rail Mounted C16a • Forest industry moved to mechanisation over two decades ago • Worldwide search comparing felling /harvesting shear, bar, and disc heads • Bracke C16a feller buncher selectedas optimum combination of safety,speed, cost, weight and noise • Clearance of trees and bushes fromthe outer running rail to a horizontaldistance of 6.0 metres. That is a bigenough task alone! • This activity is key to NR safety /performance KPIs and NR/L2/TRK/5201 compliance 13

  14. Standard C16a Risk Zone 70m Exclusion Zone Boundary Boundary Fence Fence 14

  15. Revised C16a Risk Zone: With safety kit 15

  16. Tree Clearance - Traditional Harvester 16

  17. What about…. Walking Excavators? 17

  18. Tree Processing - Hand Fed Chippers 18

  19. Tree Processing - Mechanical Feed 19

  20. Tree Extraction - Traditional Systems 20

  21. Tree Extraction - Rail Systems 21

  22. What about… Extracting Biomass as Chip? 22

  23. What about… Seasoned Biomass Bales? 23

  24. What about… A Tree Clearance Train?

  25. Heavy Mechanical Maintenance 25

  26. Road Rail Vehicle with Mulching Head 26

  27. Issues with Arm Mounted Mulching Heads 27

  28. Machine Mounted Mulching Heads Kyoeisha HMB1560 GreenMech Multi-Task 120 LUF BushFighter Posi-Track PT-100 28

  29. LUF BushFighter • 100hp diesel engine • Remote control • 2.8 tonnes • Multi tool carrier • D Bahn operate a fleet of 14 units • 4th generation model 29

  30. BushFighter Performance • Woody stems to ~ 10cm ↔ / 3m ↕ • Stump removal to ~ 60cm ↔ • Approved to operate to 45° - all planes / directions 30 • Oil pan tested to 60°

  31. BushFighter Operational Controls 31

  32. ‘Light’ Mechanical Maintenance 32

  33. Mechanical Maintenance - ‘Light’ RC • Light scrub and non-woody vegetation - NikoRobo Flail - IrusDeltrak - EnerGreenRoboGreen 33

  34. Initial Trial: RoboGreen - Wessex Route 34

  35. Chemical Maintenance - Trains / RRVs 3

  36. What about… Infrared Spray Control? 36

  37. Chemical Maintenance - Slopes & Walls 37

  38. Chemical Maintenance - Slopes & Walls 38

  39. BUT… Mechanisation has it limits! • NR are trialling a number of ideas • But… - no one tool or piece of kit suits every job - manual teams are very versatile - nothing has to date ‘replaced’ chainsaws • Selection of what to use is site and task specific • Some ideas may not become NR approved • Mechanisation fits into a wider strategy 39
