If a vehicle needs to be winched out of a very tight spot and access is not achievable from the direction that you want the car to move is it possible to somehow create a pivot point to enable the inertia to be created at a severe (say 70 degrees) angle to the initial point. For example in this picture the police teddy in the black car can't get direct access to the yellow car belonging to the cute white teddy, who he fancies, as it is bogged with a row of other teddies blocking its direct path. Is there some way that he can use his flash new winch in a safe manner to extricate her and impress the pants off her?

If it were possible to find an anchor point in the vicinity of the row of other teddies then you could use a snatch block. You would then run the winch cable through the snatch block to the white teddie's car.
You could adjust the location of the snatch block from the anchor point using extension straps or chains.
Personally that is why I bought a hand winch, harder work, but more versatile.

Wizard, you are just not nice. Snatching Teddies is a realy bad thing to do. Just think of the consequences and all those dear little kids who are trying to get to sleep tonight because YOU snatched their Teddies. (Unless of course the Teddies you refer to are of the type that some women wear to bed whereas in that case Snatching Teddies is just fine)
As far as using a snatch block or even a snatch strap, I just won't go there. The connetations on this site are just too mutch to think about.

Exactly what I have to do whenever we go to
Ulladulla to visit Annette's oldies. Their front yard is on a bit of a slope and grassy. I can "roll" the camper trailer into the right spot, but can't get the Patrol down to it to hook up when time to leave. So, use the snatch block onto a convenient small tree in garden and winch the camper back up to the driveway and then hook up...........
too easy.

Just before Pesty gets in, We always new the trol couldn't pull the skin of a custard. I could lend you the 50 to do the job if you like.
By the way, how's the Turbo going.

thanks for the offer Des....actually I reckon Elaine's scoobardoo would be a better proposition as it would have a tighter turning circle and I could probably use it to get the camper out of the yard. So, next time we go over there, I'll let you know, so we can work out how you're gunna get the little wagon over there for me!!!! hahaha
New turbo is going
well....seems to have more grunt (but that might just be my imagination). Sounds HORN though!!! hehehe
Cheers mate

If there are no trees around, you can bury a spare tire and rig off it.

Wombat, the only advice that I can give you is stick to Wombats. You are obviously out of your league when it comes to Teddies.
By the way, trying to impress female Teddies with a Landrover is just not cool.
Attempting to remove the pants of these teddyettes in this manner is comtemptable and you should be ashamed of yourself.

Don't recall seeing a Teddy with a map of Tasmania either for that matter.

I think Teddies would get lost in Tasmania unless they used a braille type map. They tend to go straight up the Derwent through Paradise and end up in a bit of a mess.

Roachie, I think you are thinking of strictly the darker Brazillian teddies aren't you? Rather than the fairer ones that Wombat was professing to rescue?
I tend to think Des is thinking in Amazonian terms too, though is just as likely going to get into jungle problems.

Let's assume, for the purpose of the exercise that the 4th teddy from the right is related to Arnie Schwartznegger and that his a'hole is firmly glued to the pavement.
Now black teddy loops his new winch extension strap around Arnie Teddy to such a length that his shiny new snatch block will be located at the pointy bit of the right hand arrow.
He then passes his shiny new winch cable through his shiny new snatch block which allows him to attach the shiny new hook to the front of cute white teddy's car, extricate her and gain her everlasting adulation and gratitude ... wink wink nod nod. But can be bare it??
Cheers

OK - I think I understand! The objective is to find a point which is as close as possible to splitting the obtuse angle and anchor a snatch block to it thus providing a pivot point for the winch line. Correct?
Two further questions if I may;
1) What if there is no solid
anchorage point in this vicinity?
2) What would be the maximum distance from the anchor to the snatch block and if it is infinite is there any degradation of the strength of this chain or anchor as the length increases?

Answer would seem obvious to most of us: White Teddy would have done what Marilyn M would have done.......forget about getting out of the predicament and jump in the back
seat with brown teddy/s and do what teddies would do if they could do....lolol

I am (will be) in this exact predicament at some time in the next two months except that the little yellow car owned by the delectable Miss White Teddy in the illustration will be actually two very old, very big and very heavy vintage cars which are about to get a new
home after 15 years. The problems will be exacerbated by the fact that these cars are at 90 degrees to Miss Teddy's and therefore will have to be dragged out sideways. I suppose without the added benefit of the collective wisdom of the ExporOz
forum I would have muddled my way through and probably come to a similar outcome . . . but now I can attack the scenario safe in the knowledge that according to those who have done it before, including the great Wizard of Oz, my modus operandi is correct. After all one of your most famous quotes is "Why, anybody can have a brain. That's a very mediocre commodity. Every pusillanimous creature that crawls on the Earth or slinks through slimy seas has a brain. Back where I come from, we have universities, seats of great learning, where men go to become great thinkers. And when they come out, they think deep thoughts and with no more brains than you have. But they have one thing you haven't got: a diploma." I now feel as though I have my diploma.

Keep in mind that you are increasing the load by angling your winch line.If you can put another snatch block on the stuck vehicle and two part your load line you can decrease the haul line tension and hook strain at your snatch block. this will help to keep your pare tire in the ground. The more parts you make the lower the haul line tension and hook strain. The quick formula for a two parted line is:HL=1.1xweight/#of parts. Your hook strain increases as you decrease the angle on
the block, a 90 degree angle increases your hook strain by 1.41.

By increasing the load Dagoboy means increasing the load on the *snatch block. The winch has the same load ( with some losses due snatch block sheave friction) as it would have in a straight pull.
The load on the snatch block itself (and its anchoring point) increases by 1.41x for a 90 deg change of pull and goes up to 2x with a 180 deg change of pull direction.
Because of this, putting another block on the stuck vehicle does indeed decrease the haul line tension but NOT the load on the snatch block, which now has to take the strain of 3 ropes.

Actually the formula for hook strain of parted blocks is:HS=Haul line(winch line) + weight of load. Whenthe number of parts supporting the load increases, the hook strain and haul line tensions decrease.

Quite frankly, I don't think any White Teddy is worth all the hassle. She is obviously high maintenance and life would be one continuous Pandaering to her wants. I think a slighly scuffed and soiled model would be more realistic as she doesn't mind getting her paws dirty and she already knows what she wants and how to go and get it. Perhaps Dagoboy could shed some light on the European versions. i.e. do they shave their armpits nowadays etc.

Wombat , when you winch yo uneed to keep the cable out in front , if you try to winch on a angle , you will snap the cable like its string the min. you ad load.
What happenes is that the cable ends up squashing and spreading over the roller . Next is the snap , dosnt take much load to do it either.
If you think I am talking from past experience , you can get stuffed lol
Cost me a new cable and fairl leader but at least it moved me 2 feet before it happened and got me out of the s h i t
