Hmm, I got a 30 foot tow strap from http://www.ultimate4wheeldriveperformance.com/ that's rated at 58,000 lbs.

I wonder if those straps on eBay have any give in them at all?

 

[ProJunkRacing]

those are lifting straps not tow straps
the difference is

lift straps are put under constand load
rather than tow rstraps that are meant to be jerked they are not the same and should not be used for tow straps my dad is a crane operator i have tons of lifting straps but i use tow staps they are not the same and should not be confused

Even though they are rated at 20,000 lbs, wouldn't the actual pulling force be a lot higher? Doesn't it take more than 20,000 lbs of force to lift 20,000 lbs of junk? (gravity?)

recovery equipment seems to be a popular thread on here so here's my .02

I used to work on towboats/barges up and down the Tx/La coast, we would use old or broken lines off the barges for tow straps,there are 3 different types of lines we used (cotton, spectra, nylon) but the nylon lines work great as tow straps, they are by far my favorite "snatch strap" meaning you can shock load it, they are a little over 1 1/2" in diameter and I have never broken one using it for a truck and they seem to have the perfect amount of give to pull a truck out of a mud hole

Uhhh........which is heavier? A ton of rocks, or a ton of feathers..........

If you had a 20,000 lb. chunk of steel sitting on the ground, it would take 20,000 lbs. of force to lift it straight up.

*best nerd voice* TECHNICALLY SPEAKING...it would take anything over 20,000 lbs of force to lift it. if it was the same as it weighed, it still wouldn't budge.

 

[resurrected_jimmy]

we are still talking about a gravity of one right, since gravity is a constant....... or have we changed it to something like a specific gravity of 3.14...... all of you with big blocks need to quit driving in the same direction...

 

[Pookster]

lol.. too funny.

Dont forget the forces of mud.

There's stickcion (spelling?) which tries to hold the truck in place.

Okay, you got me on this one. Let me rephrase..........."you could hold 20,000 lbs. off the ground with 20,000 lbs. force".

some times there are 68,000lb straps that were issued for military use on ebay. a friend pick one up, but it is only 16 feet for $25. ive seen them up to 60 feet long on ebay pretty sweet.

I wouldnt want to be underneath it.

 

[redneckdude]

i have one of the 16 ft ones like on ebay...don't use it to snatch with unless u HAVE to...sure its strong, but doesn't stretch AT ALL.

 

[dirtwarrior17]

20,000 lbs is hella of a lot on paper but when you get a little slack on it and mash the gas your putting a hell of a lot of force on it.

IIRC there were a bunch of guys who broke 20k lb tow straps.

I have.... Flight Ops are cool, especially when you put on the purple jacket one day 'cause you're bored of sitting in Combat all day

 

[Emmettology 101]

My strap is rated at 74000#. It is a 1.5" Masterpull Super Yanker. Went with one of these cause I got tired of ripping the other style. Haven't gotten a chance to yank on it yet though.... Have had it for a couple years now.

"hey grab that fuel hose this jet need's gas"

Isn't there a movie about that guy? Sounds like the starring role in "40 Year Old Virgin"...

I think what Divorced was trying to say is that pulling force is different than lifting force. You have other circumstances relating to pulling a truck out of the mud vs. lifting off of a dock. ie: inclines, suction, smoothness of the plane your are pulling over. Lifting into the air is a linear motion that is the same for the entire lift. Pulling is a non-linear equation due the the obstacles encountered.

You should see the big bastard blue rope we have at work
the hooks on the ends gotta be 30 pounds. We pull terra-gators our with them and stuff, pulled my tender truck out the other day. Last BIG feat it got used for was pulling 5 Fertilizer Rail Cars down the tracks because our tracmobile was gone. Each on of them weighs in the area of 200000 lbs
