Technological Developments In Cable Logging 1890’s 1990’s 2016 Hunter Harrill, Rien Visser & Thornton Campbell School of Forestry, University of Canterbury, New Zealand Demo Interna+onal & Conference 2016, Vancouver BC Introducon Cable Logging Systems • Common method of extracLon for steep & difficult terrain for over 100 years • % of harvest area is increasing in many countries (some more rapidly than others) • Inherently expensive compared to ground-based systems (↑capital & operang costs VS ↓ producLon) • Some companies/regions now find it difficult to remain profitable… Demo Interna+onal & Conference 2016, Vancouver BC What’s the Problem? To remain compeLLve in internaonal market requires improved “Operaonal efficiency” And overcome challenges to: • Safety • Environmental performance Samset (1985) A “step change” is required! Demo Interna+onal & Conference 2016, Vancouver BC How do we do it? TradiLonally mechanizaon → improved “operaonal efficiency” • but… It’s not just about new machines! “The only way to decrease the operaonal costs is to introduce new organizaon of the work (planning), methods (techniques) or by introducing new equipment (Samset 1985).” Demo Interna+onal & Conference 2016, Vancouver BC GIS tool for payload analysis • based of Logger PC & SkylineXL • Fully integrated into ArcMap as add-in program/toolbar • Easy as 2 clicks • Automates & opLmize spans • Covers a range of skyline systems & configuraons • Can easily download profiles to Harvest Nav App in felling machine Demo Interna+onal & Conference 2016, Vancouver BC Deflec)on App – A Tool for Measuring Deflecon in the field • Verify the setup to what was designed! • Easy process (several steps) • Laser range finder • Phones inclinometer or Suunto • Calculated from either end of span • Free for download ! yarder Demo Interna+onal & Conference 2016, Vancouver BC Drones to aid set-up • Flies syntheLc strawline/haywire • 7mm Dyneema • ≈40g/meter • 7 tonne breaking strength • Reduced man-power & Lme • 2 workers • <30 minutes Demo Interna+onal & Conference 2016, Vancouver BC Remote Control of Mobile Tailholds and Carriages • Fast line ships! • Remotely controlled by yarder operator • Camera systems for guidance • Carriage has two drums to pull towards anchors Demo Interna+onal & Conference 2016, Vancouver BC New cabs and control systems for older yarders • Designed to opLmize controls & ergonomics • Simplified 2 joysLck controls • PLC Electronic controls • Electric over air or hydraulics • Fully programmable • Easy diagnosLcs • Alarms & distance indicators Demo Interna+onal & Conference 2016, Vancouver BC Camera Systems Demo Interna+onal & Conference 2016, Vancouver BC Tension Monitoring App • New type of display • Live streaming graph (e.g. hospital heart rate monitor) • Customizable • Scroll and zoom • Color-coded zones for SWL levels • StasLcs for operang Lme • Help train operators Demo Interna+onal & Conference 2016, Vancouver BC ACDAT- ChoKer seLer tracKing system • One screen system • GPS tracking of choker-sesers • Live Lme tension display • Modelling of terrain profile • Operaons data recording • Rope tensions • Rope length meters • Engine voltage • Etc. Demo Interna+onal & Conference 2016, Vancouver BC Hybrid Yarders & Carriages • Diesel electric hybrids • 70% less fuel use (mulple weeks between refuelling) • 2000 hr service intervals (5 litres oil & standard filters) • Electric winches = smooth control & variable conLnuous power • Highest torque at lowest speed • Constant pull over range of drum layers • Automated controls • Carriage baery for clamps and slack pulling & recharges on outhaul Demo Interna+onal & Conference 2016, Vancouver BC Harvest Planner/ Future Possibili)es Forester • LiDAR → Payload Analysis • Corridors & Payload to landing → Harvest Nav App Rigging Slinger/ Crew Mech.
