I have been looking at ratchet straps to use with high lift jack for winching instead of the chain kit thats available. When i do get round to getting one im goin to go to my dads farm and get "stuck" and practise using the high lift as a winch in a safe enviroment. Hopefully i will never have to use it in real life but id rather have it and not need than need and not have! |

chain is betters as your not wasting force streching the chain as you do a strap |

in all honesty, a 3500lb winch on a towball, can pull 10500lbs with two snatch blocks, slow, but it'll do it, and its not expensive, can be used for other uses, and if its for times when you have 'bellied' out , pull yourself back, get the spade, dig yourself a clear route, try again. i have seen some on eblag for £79, another few quid for some snatch blocks and a chain to attatch to the spare wheel you have just buried as an anchor and a stop or two should get you out of most things you will encounter on a lane, if its worse than that, maybe it shouldnt have been driven ? |

2 snatch blocks - won't it pull 14,000 llbs? - If it's componants are up to it?

I think a 3500lb winch on a tow ball with two snatch blocks with a Paj that's stuck enough to need 10,000lb of pull will just pull the towbar off... |

Would something like this then be sufficient to help a little in an emergency,i dont mean 3ft of mud etc just if moderately stuck at worst.
bay of pee 350341167790 champion winch and attach to tow ball(200kg rated)heavy duty.So attach with decent winch tray that sits on tow ball.This one is 3500lb but could go for higher rated,bare in mind its not for full recovery from deep swamp |

10000lb = 4.5t approx, towbar should cope with that by design, and i was just making the point that you can get 10000lb pull for little money, so not spending hundreds of pounds on a front bumper weight that might get used once a year, also, front winch = pull yourself into more trouble, rear winch = get yourself out of the trouble, then either divert, or make a different approach to the terrain.
oh, and if a paj can tow a loaded artic up hills from the towbar, then im sure it can cope with 10000 lbs when said artic was 96,800lbs (44t), and it has been done several times last winter. |

Nope, and if the components are up to a 3500 pull, then using a pulley, the load on the winch i halved for a given load, so in effect, less stress

Well if it was me I'd just fit a rear locker !!!
I personly wouldn't give a 3.500 winch the time of day
Yes you can double the pull with snatch blocks but in real terms how many people know how to rig a winch and use one safely ?
Rachet straps should only be used for strapping a load down nothing more !
By a high lift jack with 2 rated chains and shackles and use that safe for winching junk for jacking
Don't be tempted with cheep unrated shackles or chains |

it's 14'000 lbs not taking into acount the 8% reduction on each pulley wheel(leea recommended for calculations whilst designing a lifting system). you have 2 blocks so 3 wheels. the wiki drawing is like most things on there, its wrong.
the pulley on the pulling vehicle is a single sheave, the vehicle being pulled gets the double sheave and your wire is secured back to the pulling vehicle. so it's 14'000lbs - 3360lbs for your friction through the system = 10640lbs
hows about that for a smartars.e |

right, ill take the 8% per pulley out and have 14'000lbs then
if you use and go off the drawing on wiki then it drops to 7980lbs. |
