I just had another look, could work, I don't do a lot of negative rigging, conversely I do a lot of lawn repair:001_smile:
-
Big stuff Jon, did you get wet?
-
Also as Pete alluded to earlier in the thread you couldn't remotely choke it, meaning when you stretch out and loop a rigging line around an end, catch the Krab, bring it back to where you are comfortable then choke the limb a la running bowline.
-
So I look and I look and then I figure it out! You choke the log with the prussik right? So all the groundy has to do to release pressure is loosen the prussik, then unhitch the Krab, is that right? I can see the advantages, but how prussik will behave under real pressure I don't know.
-
Never done it either or greased the bearing in the clutch of the Huskies. Sprockets seem to last ok and never had a clutch bearing go.
-
Sure, but when are the groundsmen really calling stuff down? They're the ones who need every help to process the material quicker, not the climber who on, most takedowns, is sitting in his harness watching the guy(s) dealing with the stuff.

I find clipping (and un clipping) from a rope can be a pita (as previously outlined problems getting it in and out of gate) compared to the relatively simple process of unclipping from another krab. Slings are fine, but in close quarters rigging i.e. The branch is very close to the rigging point it increases drop/shock load before the weight is taken. Slings are overcomplicating IMO.

Really? Goddamit! I'll cancel the deposit on the Aston Martin I guess.

Piège à taupe et anti-taupe. Destruction rapide de nuisibles taupiers. I have killed dozens of moles in my garden with these devices. They really work. Not sure if they're legal over there or not. If not get some sent over or take a day trip.

Ok great, I don't understand things without pictures if I'm honest:blushing:
-
Mebees, I against overcomplicating stuff but we used it today and it worked nicely. I asked the lads what they thought, they were happy not to receive any abuse from on high. As has been said, a spliced ring to replace the end Krab or a figure of eight descender to replace the free running one would work better. I'm not reinventing the wheel obviously, but I liked it!

1200 kg chipper, two man team will the weight matter?
Mick Dempsey replied to arbaholic's topic in General chat
We run A TW150 and a 1.3 tonne GM. I'm glad of the lighter chipper often. A 4wd with low ratio is very handy for reversing the bigger machine. If I were you I wouldn't fret too much, you'll love the extra power, maybe get a little hand winch to rescue or get it where you want. -
You could substitute a steel ring for the end Krab, that would work well, Clipping onto rope is what I'm trying to avoid.
-
Yes it does blow the exhaust through the chute. As for the dryness, I don't think so. Your quadchip issues are bizarre, did you tickle up the rollers with a dremel?
-
I don't understand what you mean.
-
Surely it'll come back up with the other one? The picture is just a tree in my garden, imagine it horizontal.
-
Pic 3: choke the limb, you may want to use a half hitch in front if negative rigging/not using a fork.
-
Pic 2. Throw it round, as usual.

I use a steel fixed eye Krab on the end of a lowering rope for quick hassle free rigging. But.... one of the biggest cause of rows whilst rigging is the time taken to detach the Krab, the rope is can be tricky to get in and out of the gate whilst wearing thick gloves/rain/shouty climber so I had this idea. A fixed eye on the end as normal with another running free along the line for easy attchement/detachment. Used it today, worked a treat 3 pics to explain Pic 1: one can splice the end Krab in to make it tidier if you have that skill set
-
Good pictures, circle of life and all that. Shame you couldn't have a fire for the top.
-
Well there you go then, moral of the story, avoid chipping the stuff in high summer if possible.
-
Anyway a bit of an update, this week we did a clearance of leylandii, almost exactly the same trees as the ones that caused such problems this summer. I haven't changed anything in the chipper because it's a hassle and it still chips like a monster otherwise. So, no problem at all, didn't block once. My theory fwiw, in the summer the extra sappiness of the wood and green stuff one encounters is the issue. I can't think of any other explanation. Anyone?

In Desperate times...My Silky saves the day!
Mick Dempsey replied to silky fox's topic in The Lounge
UA is tough tough work. I wouldn't fancy it. -
IMO that tree will be gone one way or the other within a few years. It should have been taken out before the work started.

Post a pic if you can, but I reckon Klein are good spikes, If they're the ones I had.
