What to do if you're suctioned down...

[benji]

As I was bored at work the other day, I got thinking about this scenario.

What can be done?

Pumping exhaust gases under the car. ..? Digging - and lots of it. .?

I've heard of a cfa Landcruiser pumping water underneath it to releasebthe suction, but thats not really an option for most of us.

Many years ago on a club outing we got stuck in "vomit Country" near Mudgee.
One bloke with a 12,000 winch just pulled himself along like the Queen Mary, but the D1 would not lift out of the mud. As he pulled on an angle he ended up with mud almost up to the drivers door window.

The solution was to put my bullbag under the bullbar inflate it then pull with the winch only say a metre and roll over the bullbag. This was repeated a couple of times and he popped out.

Some of the cars were down to sills and water then welled up around them and the bullbag was less successful as it kept sliding out from under because of the slipperiness of the water /mud mix..

BUT in general the answer is to have 2 means of recovery and use them in combination. Say a winch plus a bullbag, or plus a set of maxtrax, or sandbags or high lift jack or whatever.
By using 2 in combination you reduce the chance of equipment breakage.

In fact I recall the first attempt to extract this bloke ended with a snatch strap breaking which destroyed the tailgate of the snatcher.

General principle when badly bogged is to get the front up before you pull. (Or the back if pulling out backwards) Basically jack it up and try and fill the wheel ruts with anything available that will not squash out when weight is put back on wheels. I was involved once with getting two D2 sized dozers and a bogged header out after initial cowboy efforts to unbog the header. First got one dozer out. Then with decent operators on both, header on rice tyres was extracted backwards by pulling combined with its own power. Then both helped the second very badly bogged dozer.


This one had the top of the back of the tracks at ground level and the top of the front only slightly above. Technique to break the suction with both dozers - which was enough tor the first dozer to get out under its own power was to put several sleepers under the blade, then push it down to lift the front. Then a lot of sawn firewood like timber was thrown in the front of the ruts. Repeated until the bottom of front of tracks were above ground level while sitting on this before pulling was attempted.


Need similar general practice when a wheeled vehicle is bogged in soft mud that wheels will not climb out of. Most likely using some sort of jack(s), preferably high lift and/or bag type.
