Introducon Systems • Common method of extracon 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 ↓ producon) • Some companies/regions now find it difficult to remain profitable…

Demo Internaonal & Conference 2016, Vancouver BC What’s the Problem? To remain compeve in internaonal market requires improved “Operaonal efficiency”

And overcome challenges to: • Safety

• Environmental performance Samset (1985)

A “step change” is required!

Demo Internaonal & Conference 2016, Vancouver BC How do we do it? Tradionally 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 Internaonal & Conference 2016, Vancouver BC GIS for payload analysis

• Based of Logger PC & SkylineXL • Fully integrated into ArcMap as add-in program/toolbar • Easy as 2 clicks • Automates & opmize spans • Covers a range of skyline systems & configuraons • Can easily download profiles to Harvest Nav App in felling machine

Demo Internaonal & Conference 2016, Vancouver BC Deflecon App – A Tool for Measuring Deflecon in the field • Verify the setup to what was designed! • Easy process (several steps) • Laser range finder • Phones or Suunto • Calculated from either end of span • Free for download !

yarder

Demo Internaonal & Conference 2016, Vancouver BC Drones to aid set-up

• Flies synthec strawline/haywire • 7mm Dyneema • ≈40g/meter • 7 tonne breaking strength • Reduced man-power & me • 2 workers • <30 minutes

Demo Internaonal & Conference 2016, Vancouver BC Remote Control of Mobile Tailholds and Carriages

• Fast line shis! • Remotely controlled by yarder operator • Camera systems for guidance • Carriage has two drums to pull towards anchors

Demo Internaonal & Conference 2016, Vancouver BC New cabs and control systems for older yarders

• Designed to opmize controls & ergonomics • Simplified 2 joysck controls • PLC Electronic controls • Electric over air or hydraulics • Fully programmable • Easy diagnoscs • Alarms & distance indicators

Demo Internaonal & Conference 2016, Vancouver BC Camera Systems

Demo Internaonal & 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 • Stascs for operang me • Help train operators

Demo Internaonal & Conference 2016, Vancouver BC ACDAT- Choker seer tracking system

• One screen system • GPS tracking of choker-seers • Live me tension display • Modelling of terrain profile • Operaons data recording • Rope tensions • Rope length meters • Engine voltage • Etc.

Demo Internaonal & 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 connuous 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 Internaonal & Conference 2016, Vancouver BC Harvest Planner/ Future Possibilies • LiDAR → Payload Analysis • Corridors & Payload to landing → Harvest Nav App

Rigging Slinger/ Crew Mech. Felling • Recon → Roads, Operator landings, tree vol. & • Harvest Nav App location guidance • Install yarding corridors • Bunch (Payload to landing)

Communicaon Routes

Demo Internaonal & Conference 2016, Vancouver BC Conclusion

• There are a number of new developments out there and more to come… • Clearly a “Step Change” is already underway! • Improvements & Success? • Not just new machines and features • Improved planning • Successful implementaon of new techniques • Embracing new technologies • Be proacve- trialling, learning & stabilizing these new technologies
