My company runs the GRCS for any jobs that require anything more than a couple rigs and are very experienced with it. They taught me that any lowering must be done through the pigtails and that anything 3 wraps and over will jump unless lowered extremely slowly. Really only applies to massive...
My company is in the thick of storm work and we need to get a lot of chain fast to avoid sharpening while we are swamped pulling 12 hr days. Hoping people can share any online ordering that went well for bulk orders especially with a few different size chains. My local dealership kinda sucks in...
That's what my friend guessed but they also pointed out they only get bark like that when they are mature and when I look at pictures of white alder they seem really big and still smooth barked, these were like 20 ft tall and super rough
That
That was my original question and it has been answered: it's not a significant difference on the intended outcome between either method. Thank you everyone again for the input and helpful diagrams
I love arguing semantics, so this thread hasn't been frustrating or disappointing to me.
I have heard this from someone with a lot of experience, he doesn't like to tie anything very high (55-60 ft+) due to diminishing returns due to the pull angle but I didn't really understand why until this discussion. If nobody asks that in a separate thread I might.
I enjoy learning and spirited discussions, so carry on. I understand that with a pulley with force on both ends the vector is between the two original forces. I don't understand if friction or the efficiency of the pulley matter for that part of it.
And I think it's relevant to discuss, I...
I don't know what to think here because I'm too dumb to know whose more right, but I'm grateful for the discussion and I'm going to keep an open mind and keep reading about MA systems and how they work with vectors and magnitudes and forces. Thanks all!
I think what Shadowscape is saying is right because the force applied to one side of the pulley, or branch, is just mirrored on the other side, or multiplied by a factor. It's not divided and distributed across both sides.
When setting a line in the tree to use to pull it over, what is the difference in forces between a basal or canopy anchor?
In an attempt to be more clear: say you set 2 lines 60 ft up two identical 100 ft trees and then pull on them from 150 ft away one is tied off just above my notch and one...
Hi all,
I have finally gotten to the point where my ground saws with 3/8" Full Chisel chain that I round file cut beautifully straight and fast all the way to the last sharpen. With top handles, I've always let someone with more experience file them since they are a little more indispensable to...
I couldn't tell you, I figured that they would be either heavier or less sturdy than what I'm used to which is not what I'm looking for. I'll take your experience into account though, thanks.
