There are various cable assist machines that have been going into NZ forests. https://youtu.be/PQB4e1LXJII (North Island) Dozer https://youtu.be/ZcMO6sgqefM (South Island) Excavator
Yair . . . Interesting stuff and probably a couple of the best promotional vids I have seen, highly professional and a cut above a lot of stuff on Youtube . . . the drone technology has come a long way. Thanks for posting Plebian. Cheers.
I've seen a yoder dragging equipment up a steep cut, but the operator hadn't run down to the bottom on purpose. lol Greyson
I've heard that the concept is being talked about for here. The concept is interesting but I'm sure the government will want to put their $50 an hour into anyone willing to try it.
D85 Winch dozer...
Self leveller attached to two cables...
Eric Krume @ Summit Machinery and Attachments has designed a tethering system that is in use now. It is paired with a Tigercat 855.
While that bucket never seemed to move on that excavator, I think having a blade buried would give me more of a warm fuzzy feeling as I broke over the edge.
Remote control John Deere. A trailer for the rc operator like 'drone operators' trailer has been mentioned. http://www.3news.co.nz/business/rem...ling-reduces-hazards-2015091916#axzz3pl3ih7ew
Madill cable assist with Tigercat 870c feller, Link Belt heel boom shovelling, excavator processor on roadside. Should there be two machines shovelling to keep up with the Feller Buncher? Could a plain grapple shovel faster (less weight in the boom) than the heel boom Link Belt that has more weight extended on the slope? A dual bogey Tigercat skidder or clambunk (even some self loading crane forwarders) could pull most of that terrain or are the enviromental rules so strict in the logging area that this terrain can only be track machine shovelled or cable logged (heli uneconomic)? https://youtu.be/Ria0Bmdka9M Could try bulldozer/ excavator tether machine, Madill felling/ bunching, Tiger cat shovelling and Linkbelt- shovelling/ fleeting/ loading and processor base - (processing/ loading)
Excavator tether with tigercat leveller. It is easily seen how potentially hazardous these sort of trees can be to chainsaw fellers. https://youtu.be/zZfwPcZmtpw
Falcon Winch Assist by DC Equipment. High hour machine with cable drum, radio control etc. https://youtu.be/Md8A5E9C9xg

Great videos of machines working in on some steep slopes, the last video helps understand how it all works. Thanks for sharing.

One of the newer Tigercat LS855C (Tier3 Cummins, upgraded hydraulics) - near Dargaville, NZ - trees up to the 8800 lbs/ 4000 kg range. Connected to Hitachi ZX280 winch machine on steeper terrain. https://youtu.be/mTW7lfMKYCE

Part of the reason it’s shovel logged is price and efficiency as well as it’s all tree length wood.
DC winch assist in Wa (new builds using zx280 for winch machine)
T-winch 20.1 (there was also a 15.1) 20.2 model being worked on specs: weight of 64K lbs (30 metric tonne), 560 metres of 26mm, 1840 feet of 1 inch winch rope, 15 metric tonne line pull, 33K lb line pull. 414 hp . 20.2 intended to have improved line speeds of up to 8 metres/s? to improve reaction time for felling machine control.
NZ has a NES rulebook (national environmental standards for forestry) and regional environmental rulebooks . Been a few court cases over recent years of driving logging trucks across creeks instead of putting in bridges, un-permitted large earth works to get logs out etc 6? forestry related companies have court time looming for environmental problems. Another 'test case' forest area could potentially be taken out of pine plantations and put back into native/ indigenous flora to keep the greenies happy and so the tourists don't see brown clear cut hill sides when in a tourist town. T-winch 10.2 with jd forwarder on the wire.
