Unresearched question - rope blocks or wire ratchet to secure trunk of tree when cutting

Mar 31, 2019 Last reply: 7 years ago 8 Replies

Undertaking a bit of tree trimming.



So far the trunks/branches have been fairly slim so all it has needed is a guide rope and someone to pull to ensure that the cut bit falls in roughly the correct direction.



Now moving on to larger branches and main trunks. Above a certain weight the "puller" is likely to become a "pullee" unless very gentle guidance is needed.



Two options seem to be:



(1) A strong static load using a wire ratchet hand winch, such as one listed in

. Advantages; as long as it is secured to something robust (another tree trunk) then a lot of pull can be pre-loaded.



Disadvantages; once the branch/trunk starts to move then the pre-load is lost and the branch will at most describe a fixed arc.



(2) Less of a load using a pulley system such as

still fixed to something robust (obviously).



Advantages; the person pulling can in theory move backwards as the branch starts to fall and pull with more direction than a simple tether.



Disadvantages; it may not react very quickly. Requires active person in the region of tree felling.



Noting that there must be enough rope to keep the puller well away from the target area for the falling limb.



I'm off out to a Sunday market so I will have to delay online search until later.

When I were a lad, I cut down a large willow in my mother's garden. It was a multi-stemmed tree, about 20ft high. Rather than letting it fall where it would (it was on a shared boundary and I didn't want it falling into her neighbour's garden, as it would have demolished a shed), I attached a rope as high up as I could get on a ladder, cut the largest trunk about three quarters of the way through, and then heaved on the rope, expecting to break the remaining uncut bit in a reasonably orderly fashion. The trunk didn't immediately break, so I heaved harder, and suddenly it snapped. I fell over backwards, landing in a rather thorny gooseberry bush, and the tree landed on top of me.

Fortunately, no serious damage to me at least, apart from a few scratches and hurt pride, but the gooseberry bush was pretty well demolished. (I'm passingly reminded of Hoffnung's 'barrel of bricks...)

So be cautious about pulling on a rope to encourage and guide the branches or trunk down. It may not go according to plan.

Hoffnung's version:

You anchor a stake into the ground, attach a rope with ratchet puller. Keep ratcheting, the tree will bend, and eventually the stake will pull out of the ground. The real questions are how far it will go and what destructive power it will have when it arrives?

Rather than trying to re-invent the wheel (and possibly doing something very dangerous) I?d strongly recommend looking at some of the very many YouTube videos on safe tree felling, branch lopping etc.

+1.

At the least a car and a rope hitched to it will eliminate about 270 degrees of possible fall angle.

wedge cutting first generally limits fall to a few degrees and then a rope is handy to pull it over just before it goes and avoids being near the cut when she falls - there is always some kickback.

But a car will do quite a lot of damage if you do succeed in turning the whole thing into a catapult. :)

I may, of course, need help in the construction of a drive to get the car close enough to the tree.

The second problem is that the garden is relatively small and steeply sloping upwards with not enough clear space for a car to take a run at pulling the tree without landing in the kitchen with a tree on top.

Apart from that..... :-)

The tree cutting videos are useful but mainly seem to be from the USA where trees are large and spaces are also. A "come along" features in some which is what I would describe as a ratchet cable puller (see OP). However there also seems to be about 100 metres of rope and a big tree to fix the other end to.

Haven't found a reference to using a pulley system to help control falling trees (apart from in one of the reviews)so the "come along" might be the favoured option.

I do have some experience (gained over many decades) in taking trees down and haven't had to resort to major pulling until now, which is why I was asking for advice/suggestions.

The rope is mainly to guard against getting the wedge cut wrong, or the branch/trunk being too top heavy.

If I decide on mature consideration that it is looking too top heavy then I will refer it to the professionals, because I'm not going to learn tree climbing with a chainsaw at my age.

If you duck then will that count as a miss stake??

Thank you.

I'm here all week.

Come back after you've done that then.
