Nylon sling question

put them on a bench and hit them with the heaviest rubber mallet you have, or a small sledge if that doesnt work. This should loosen them up enough that you can (carefully) get a screw driver into the knot to work on them a bit more. you naughty boy

If I have this problem, I use some clean soft jaws on my bench vice and clamp one side of the knot in the jaws bend over the other side with a cleansoft mallet to loosen it up repeat till you can push the slip knot apart. the secret is to hold one side of the knot tightly whilst you move the other side. away from the tightening up direction. hope you follow.

I have seen a sailor's folding knife where one of the "blades" is round, pointed and very slightly curved, kind of like an obese ice pick. You work the point into a loop of the knot, prying, twisting and pulling until you develop a little slack. Then you do more of the same until you can untie it.

Since this is a metals group, I suggest you make one out of a piece of 1/4" round stock.

Cut them up and throw them away. Never tie knots in nylon slings. If they have pulled so tight that they cant be untied the fibers have been crushed and they will now be greatly weakened. Can and will fail under loads much lighter than what they are rated for.

They're called marlinspikes.

My S/S rigger's knife was $4 + $4s/h last year and I keep it in my GO bag.

He might also soak them to soften them up, but another poster was right. Once he's knotted the shit out of them, he should just throw them away since they might have been damaged by being abused like that. I sure wouldn't want to work with abused lifting slings when it's my ass on the line (nearly) underneath them. LIfe and mobility are much too precious.

And before the next time, get yourself one of these, OP, and you won't have to toss all those expensive slings ever again:

sale for $9.99!

I keep a marlinspike around just for these sorts of impromptu events...

Political Correctness

A doctrine fostered by a delusional, illogical liberal minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

According to Leo Lichtman :

Yep! It is called a "fid".

or perhaps 3/8" round stock for the task at hand.

Enjoy, DoN.

True, I always have a snatch strap in the Patrol and usually use it to pull out bogged cars at the side of the road.

However, today I used it to drag my lathe (600kg?) from the middle of a 40' seatainer to the door, then I lifted it with the forklift attachment on the tractor FEL. Being cautious, I used 3 1000kg rated ratchet tie down straps, one around the FEL frame to get the lathe as close to the tractor front as possible, the others over the tines. It was not very happy lifting it, never more than 50mm above the ground, but idling in low/low (12) it moved the lathe into the shed through the side door with only one problem. The soil has recently been dug up and one rear wheel sunk and the tractor tilted. The lathe immediately grounded but the metre length 4 x 4's bolted to the stand prevented it from tilting and falling.

That is the only fault with the FEL compared to a forklift or a bobcat with no suspension, any surface irregularity at the rear causes a disproportionate movement at the bucket end. My tractor is an Iseki 22hp and it needed the cultivator on the back to balance the lathe. The heaviest thing is has moved is a Tecalemit 2 post car hoist. Grunt, groan.

(mindless topposting corrected)

I've never had a hook come loose during a pull, only during a slack period. I tend to hook them on the top lip of the frame. Besides, nylon doesn't stretch enough to "turn a hook into a lethal weapon". Rope and cable do.

Of course, I've only towed things out with a 2WD vehicle, a half ton pickup. Parameters can change as the weights go up, and I've seen tow truck cables snap (But not while I was making a pull with one. I've never done recovery work though I have towed vehicles.) with many tons of weight on them. They whip mercilessly. I stand well clear of tow lines, as every semi-intelligent being should. All semi-intelligent people should make sure to keep the idiots clear while they make a pull, too.

Have an old sack/ blanket wrapped on the middle of the tow line, if it snaps it will not whip so violently. Alan, in Gosnells, Western Oz. VK6 YAB VKS 737 - W 6174

After chastising someone for top posting, "Larry Jaques" wrote the following ludicrous statement:

Besides,

Huh? The elasticity of nylon is not as bad as some other synthetics, but ALL materials has some degree of elasticity. You must not have seen a nylon sling part. Yet.

Right! But make sure you put two of them on the line, one on each side of the break!

Right, but lose a hook from one end and it pretty much just hits the ground after the inch or so of stretch normalizes, though the towing vehicle will probably move a bit, too. Have you (or anyone here) ever been hit by a hook from a tow strap like the HF item I posted?

No, I haven't, luckily.

I watched the Modern Marvels video of the super-rope testing. It failed quite catastrophically at something like half a million pounds pull. Spectra "fur" flew EVERYWHERE! Spectratacular.

Buddy of mine had to replace the rear window of his pickemuptruck. Hook came through and nearly took his head off.

Did he have it wrapped OVER something so it took to the air when it let go? Always wrap bottom to top so the loose part hits the dirt instead of getting airborne. That was one of the first lessons I learned from the regular tow truck driver when he was giving me my full ten minute course on on-street vehicle recovery.

Anyway, I'll give odds it wasn't from stretch, but from wrapping. When the hook cut loose, it was wrapped over a foot of whatever and got some velocity before making that 90 degree bend toward the rapidly accelerating truck which no longer had a load on it.

He learned a physics lesson the easier of the hard ways--it hit the window, not him--if indeed he learned it.

As far as I can remember..he was trying to pull out a stuck backhoe with his pickup and had simply hooked the end of the nylon towstrap on something on the forklift and they were trying to rock the beastie out of the mud. Somewhere in the process the hook came undone under load.

he said...he never even saw it coming and he was looking over his shoulder at the backhoe..and suddely he was covered with busted safety glass and rancid spit and tobacco juice. Seems the hook x-ringed the spit cup in the drink holder on his dash.

If you're gonna rock, tie the hook on so it can't release that easily, and remember to hook it so the hook drops instead of going airborne. IOW, he should have been paying attention to what he was doing and where the pieces would go if they came loose.

Double EWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW!

One last question: How the HELL do you stick a (running) backhoe?!?
