if fort bragg is where this is being done that country is basicly flat .nothing like the nw
I understand that, I get what NW Oregon and SW Washington is like. Europe has been doing remote control thinning on steeper ground for a while as well, but there’s still no replacement for a guy in the seat to make the call or rules that say this is the limit.

Well after running our tigercat hoechucker/shovel logger on 55% to 65% for the week hooked up to the EMS winches its like cheating, gets around like its flat ground. Haulback maybe try the guys at https://integralequipment.ca/ they are distributing the alpine shovel logger up in B.C their brochure says it can tether also.

Pardon the ignorant question, but why not have an excaline up on the road to elevate the cables, hang the grapple from the cable and dispense with the machine on the hillside?

Road and landings are at the bottom and a conventional grapple yarder would have done a good job on this patch. We tried a harvestline with the Hawkeye and didn't have the power to get the grapple up in the air at the backend. Found it needs a ton of lift.

I like the setup you guys are running. And I agree with a harvest line you need to have a ton of power in those winches to get it up in the air in the tail end.

I ran a thunderbird tsy 50 with a different contractor for a couple of years and it would have done pretty good on this block.

We are just starting to get the hang of our TSY 155. Have you ever rigged up the mechanical grapples on one? I never have nor have I threaded new grub lines or drop lines through an MSP Carriage. Any tips and tricks will be greatly accepted

How does that running skyline do with a hydraulic Carriage like that? It seems that the carriage would be too heavy but I have to think that mechanical grapples are close to 3000 pounds.

For the grapple johnson industries has a pichttp://www.jlogging.com/gpspec1.html showing how the cable is run thru the sheaves and the pic also shows what they call the 3way slider which your main, slackpuller and closing line are all attached to using knobs. We always kept spare closing lines on the machine. Changing the closing line cut the line about a foot from both knobs and throw them knob first at the grapple as hard as you can that will loosen the wedges.(they will bounce back and try and hit you in the shins)

The MSP had spliced eyes for the main slackpuller and dropline with a flush shackle so it could go through the sheaves in the tower, that is how we ran ours. Also there should be a valve somewhere on the air system to change the pressures on the mains to open the grapple on the outhaul and with the MSP reverse the pressures so the dropline isn't dragging in the dirt on the outhaul.

Johnson also has a mini MSP carriage that is has hooks for the chains on a grapple then you drop the the grapple throw a 40 foot dropline on and some chokers and choke out a spot that has crap deflection(ie lines in the dirt). Did that with the regular grapple carriage for a couple hours one day instead of hooking the choker onto the grapple.

Regular grapples run 2500 to 3000 lbs for a 3/4" machine. The hawkeye carriage is 3000 lbs but the big downfall is the grapple closes when it drops down and opens by lifting up loosing valuable lift when you need it most. Regular grapples pull the grapple up to the carriage when you really pull on them and the harder you pull the more they tighten onto the wood. I would look into the camera for the grapple though that was a nice feature on the hawkeye. Really needed it on that thing though 52" opening is really tiny when you are out 800'.

A really good op and hooktender on a grapple yarder can make a huge difference. Murk100 would probably have some good tips to. Hope that 155 works good for you.
