used my GRCS to lift tree of house today

it was doing it, up until the very end, then it started slipping on the capstan winch and the video stopped. Tackle would have increased the pull force, but would have been even more slow.

What did you do when it started slipping? Where did you go from there, several options available...
 
OK X,
Now you made me go watch this vid. I didn't want to but you MADE me!

PS... looked like a good time to pull out the saw and start cuttin'... plenty of lift... just still stuck on the stump...
 
The grounds got nervous cause the tree was cracking so he stopped for a second. It had plenty of pulling force still left. We stood it upright, put a tag line on it and pulled it away from the house with the mini while we cut.
 
Sometimes if the grcs starts slipping a bit, you can get another guy to pull on the standing end thats feeding out of the capstan and it can be enough grip to get it going again. I've always wanted to do a double whip tackle but you sometimes you need a lot of rope for a system like that unless what your rigging is close to the ground. ahhhhh just watched the video, pretty close to the ground.

I found that having a full set of rigging gear can help you in those problems where the good rig just can't go any more, as you can secure the piece using a portawrap, or even take up the stretch in the rope with an add-in 4:1, then readjust your strategy. With the new groundies sometimes they let the rope roll over itself in the capstan, but being able to whip up some conventional rigging can usually get you out of those problems. But really knowing the limitations of the device before you start the lift is crucial.

Decreasing force at the rigging point and reducing stress on the equipment should be considered when approaching any rigging scenario.

Slow is good.
