Tractors and wood! Show your pics

The snatch block actually needs hooked on that tree if you’re trying to double the pulling power. Then hook one end of the cable to a tree in the direction you’re trying to pull and hook the other end to the tractor.

You can run a single line off of the tree to a safe and comfortable working distance, then hook that single line to the snatch block. A lot easier to rig on the ground than up in the tree.

I have a friend who is a tree removal specialist...he has a slingshot he uses for ultimately getting secure lines on insecure leaners etc...I thought what a good possible use a drone might offer for similar tasks...

Yep, just gotta be sure that your single line has a working load limit that can handle the doubled force that the block creates.

Oh yeah. Put a 5000# line on a 10,00 pound pull and you get a nice slingshot or whip!

Speaking of that type of thing, many years ago my in-laws were getting firewood with a friend of theirs, and they wanted to try and control the direction of fall of a large tree, with a small rope tied to their pickup truck! Well that rope stretched and snapped, came flying back and hit my mother-in-law across both thighs! Knocked her to the ground, ripped her jeans and left huge bruises for weeks. Lucky it didn't hit her in the head or neck. That was the last time they ever attempted to fell a tree.

Yikes! The speed of a stretched rope snapping through the air gives you no time to react. She is a very lucky woman.

But the use of the block cuts the load on the line in half.......
Add another snatch block & you cut it to a third, that's why you use them.

I can hold a truck in the air if I have enough strands of thread.

Not exactly. It increases the pulling strength, but the load on the line is potentially still as high as the tow vehicle can pull.

 

[goeduck]

that is a great thought! thanks!

Agree. Roll your own leaner. :thumbsup:

The single line that ties the load to the block is the one that has to handle the full force of the pull. More blocks and lines makes no reduction for it.

However, we're not talking about that line. We're talking about the line that's attaching the pulley to the tree. That one line will be three times the load on a two pulley rig.
