As I clear sections of my block I have many tree stumps to deal with. When the dozer is here it's aka good, that 25T D6 will push over/uproot a large Iron bark in 10 sec flat. When it's just me and the tractor it's another story, even when my 100HP tractor weighs 5-6 ton.
That led me to this attached video which I found mind blowing. Unfortunately the procedure in the video is NOT well explained. However it became my catalyst to dig into this more and find better explanations. I will link the other videos a bit later.
PS / heads up with a foray into this field it is definitely worth looking into 'winching fails' type videos to see how dangerous things get if you don't rig things the right way aka Shackles and wire ropes which become supersonic projectiles etc.
Anyway here is what is possible if you're a rigging genius. Personally I'll be using much less mechanical advantage (10x with 5 pulleys) because I have a bigger tractor and I don't have lots of that expensive super strong static rope.

Here's a bit more explanation

And this video of some other folks who went down the pulley journey, I found yo be very useful because they made mistakes, discovered the subtleties and explained the ways that did and did not work ... and a bit of pausing on their video confirmed the rigging/ hookup methods.

This should be considered the how not to do it video.

This one is longer than it needs to be but it does show what happens when cables break and it will make you think twice about how you protect against snapping cables.

The videos of people spinning wheels and tearing up equipment are there because they are morons with a chain or pulling straps.... Fun to watch once in a while, but only on a "what not to do" basis..
There are several videos of pully and block and tackle type set ups that are in the range of 25 or more to 1 that may be time consuming to set up, but work well and safely the first time.. Well worth the time to learn how to rig up and use..
I have an expired (by date) roofers safety rope about 70 or so meters long I have used in a set up with 6 parts to retreive timber almost a meter in diameter.. This a lodge pole type pine that was growing up with a parasitic twin at the base.. I sawed the two apart vertically to where I could fell the smaller trunk.. Rigged tention on the bigger one to fall where I wanted it.. Notched, plunge cut, and when I cut the trigger it popped over right where I envisioned it going..
Part of the plan was setting up multiple anchor points to rig line parts to, and having my tractor off to the side of all this... My tractor is maybe 1 1/2 tons fully dressed with loader, loaded tires, chains and skidding rig.. But more than enough to keep enough tention on the set up where needed..
Keep safe..

I was curious, so I did a Google of 25 to 1 stump pulling..
Found this little video that shows it pretty well..
Problem seems finding single or double blocks to rig with as they are quite expensive here, and hard to find at garage sales...
Adapt, improvise, overcome...
Keep safe...

Tim the little tractor big stump video is the one I meant to post in my first post of this thread! Must have copied the link correctly. Anyways I have edited the original post to include it now. And yeah that guy is very clever. |

good videos and well worth watching, even for people familiar with using snatch blocks

The last thing I'd put in a bug out bag is a pulley. More food, maybe, or more water, maybe even an inflatable girlfriend, butt not a heavy metal pulley.

Sailing pulleys are extremely lightweight. The two links I posted weigh approx. 60g each.
Whilst they don't have the capacity of the one Spatial provided a link to, they should be enough for emergency shelter building.

Use trollies, wheelbarrows, bicycle, carts etc.. There are plenty of ways to carry substantial gear in a BOB or INCH bag. |

Won't using a trolley, cart or wheelbarrow restrict you to established roads and tracks? The sort of places most refugees will be using, the sort of places most of those who would prey on refugees might also use.

Seeing this thread is about pulleys, I'll start another thread about carts. |

Thought of another use for pulleys.
If having to cross a river one could rig up a pulley system to cart a number of heavy loads across without the loads getting wet.
