Winches self release snatch block problem

[Hoobie]

Hello friends. need advice.
I have a Kubota mx5100 as well as an old Ford 641. Wallenstein logging winch. I have been doing firewood operation for 40 years and finally purchased an Igland self release snatch block. I used it for the first time yesterday and had problems. instead of releasing the choker slides usually just jammed up against the pulley instead of tripping the release. Tried different angles, heights and even upside down. What am I doing wrong? Any help is appreciated.

It looks like it just keeps pulling. How much you trying to pull? If you're pulling too heavy it probably won't release and stay in the groove.

Hmm, picture of your chokers? Wire diameter? The release is not to stiff and tight?

To me it looks as if a collar or choker that secures log should release cable guide and block should drop free unconditionally... Would believe it may have a bind at guide pivot point or choker is not shaped/guided proper to trip the cable guide retainer...

I am sure you are rigging like this ????



In looking at the Ingland block picture I see here: https://www.ebay.com/i/113734223555...xauu0T7LEe3GsNQSXzvc-d9zzYuOkyVBoCs68QAvD_BwE

I see what might be a problem. There has to be room enough for the slider to run around the sheave in the groove w/o binding on anything. If the slider hits a binding point before the trigger it will jam. To me it looks like that block/spacer that is under the trip lever does not leave enough room between it and the sheave for the slider to pass by. I would look at that closely and maybe find some smaller sliders, or make a small dummy slider thing you can put on your cable so it hits the snatch block first and can pass thru that space to trip the lever, or just grind back that spacer - I don't know why it is so long but there must be a reason I don't see so go a little at a time.

I have 3/8 cable with standard size sliders. The release arm works freely by hand. The slider usually never gets to the release arm but butts against the pulley and stops. Not pulling anything excessive.

Try rigging with the part of the snatch block that has the release arm facing down toward the ground.

I think if you look close you might see that the slider is butted against the pulley and that rectangular block spacer under the lever so it can't enter the pulley to trip the lever. You need to correct that interference or make your self a smaller pseudo slider thingy that won't jam against that spacer but will swing the lever.

I own this type of snatch block and never had any trouble like this, pic of the sliders?

That is good - you will be more help to him than me. I am just guessing on how it could jam. I agree that pictures are needed.

I tried the picture. Never did it before. If I fail will try again. Any ideas for a dummy or pseudo slider.?

 

[Hoobie]

Maybe that worked

What exactly is your slider jamming against? can you take a picture of it when jammed? I've got two different self-releasing snatch blocks (unfortunately, neither are identical to yours). I've never had a problem with the sliders just jamming against the pulley and stopping,

I have the same s/r block, no problems. I may have smaller sliders (for 3/8 max) chain chokers, but you do need to use it with the wheel facing down.

As mentioned, rig it up again, and take a picture of it as it's rigged. Maybe that'll show a problem for the guys that use them.

 

[Hoobie]

Ok. In a day or two when I am out again I will take a picture. Thanks all.

Is that specific to this s/r block or is that for all of them. I have used mine both ways and never had a problem releasing, but maybe I have just been lucky. Always wiling to learn more.

Actually in this video made by Igland they clearly show their s/r s/blk set up with the open face up. So there you go - intuitively you would say facing down would be better because the cable would have less chance of fouling coming off the sheave but there is not much for it to catch on if it is facing up. So either way works..

It will be interesting what Hoobie's problem turns out to be.

That's the thing I was looking at too but then I thought that it must swing with the release lever because it does not make any sense to have something solid right there. :confused3:
