Bogged the Mog..

Bogged the unboggable!

Hi,
Take 9 boy scouts ....... no, that was a bogged kombi.


Waiting for the rest of the tale.


Cheers

its not bogbbbged yet, I can still see the tray and the door handles.

if its got its full CES and is FF that thing is coming out under its own power.

[Disco Muppet]

I agree with Dave, that's not bogged.
Hell, we bogged ours FAR worse than that and we were only a bunch of cadets.
When a mog is sitting on it's chassis, THAT'S bogged.
Of course, I got to watch the Army try and snatch it out with 3 perenties chained together. That wasn't pretty....

Ha, thanks dave, true the tray isn't under..but the back diff and tow bar are on the deck as well as the crane leg.. I have no idea what the hell CES and FF IS, some sort of military talk no doubt..I've recovered a fair bit of bogged equipment, and Trust me it's bogged and in no way was coming out under its own power, sure, if I was on my own and stranded I would have got it out given plenty of time.. our 140 grader wouldn't pull it out and ended up bogged itself, different country down here when it gets wet, to what you've got up here.. Volvo digger pulled both out with some effort.. One thing I've found with the Mog is that these tyres are near useless off road, they are crap on wet grass, rubbish in mud, and terrible for floatation even when aired down..good in the rocks and shale though..

I would've thought a grader was impossible to bog,,

Where's Andy when you need him?:p

yeah the double coils are crap.

CES = Complete Equipmetn Schedule
FF= Fully Functional
If the crane was working it was coming out under its onwn power, I never said it was going to drive out...

if you havent sunk the outriggers you use the jacking pads to disperse the weight and if you need to you double stack them on one side and then use the spare tyre under them. jack up one side and fill the ground, repeat on the other side.

If you need more lift set the apre down pad it fold the crane over so the tele is verticle then extend. if you overload that hydraulic circuit you can short slide the tele and use the shoulder joint to push down. be careful though as it will walk the head of the tele on the pads.

you can also ue the slew to get some forwards push as someone eases it out in first but thats really really dodgy.

If your on the axles and you cant lift it with the hydraulics...

chock the chassis at the back as far outboard as you can, strop the wheels use the crane to compress the suspension and then fill in the ground back of the crane an the suspension will lift the chassis, alternate side to sie and keep going till you can get the jack under the chassis jack up and keep wheel filling.

it takes 4 people 8 hours to get a fully loaded stores mog out of about that badly bogged but it beats just waiting for the 2 days for the recovery crew to come out.


CES is the complete

Pedro, graders are surprisingly easy to bog, massive amount of weight on the tandems, and a belly plate that runs from the front of the rippers to the front of the cab, you've only got to just above the 'diff centres' before they will belly out, then the belly plate acts like a giant suction cap and your in the crap..
Thanks dave, considered using the outriggers, but never thought of the spare tyre as a block..great idea, I suppose the army had some pretty 'do anything to get out of a bog training ideas..

And it looks so innocuous!

Will you be looking at new tyres after that?

[Summiitt]

Would love to, but the things got to earn its keep, plus the tyres were brand new so only have 12k on them.. Will keep an eye out for something with a wider footprint down the track..but from experience, once you break thru the top 4 inches, tyres mean very little..it's all about floatation!

[spudboy]

Would a winch have helped?

I've thought about putting a winch on my MAN, but the proper sized unit is stupidly expensive. So far the Air CTI system has got us out of all the bogged situations we've got into (but nothing like yours).

[Summiitt]

A winch would have helped, but the issue with after market hydraulic winches on these mogs is that the pto that powers the crane doesn't have the cooling or oil capacity sufficiently big enough to run the winch continuously..then you've got to find something big enough to hook it onto.. I do have a 50,000lb hydraulic winch off my last MA911 merc truck, but it would need some serious engineering to make it a bolt on unit onto the tray of the Mog..one day perhaps!

landrover rims with 7.50 R16 rubber on them with a 4mm steel plate welded or cut to fit the rim lips with a centering ring for the outrigger foot are ideal for your outrigger pads in the situation you got into.

conveyor matting in 3m lenghts with holes drilled for cross bars that can be threaded through are great for load distrbuitn and park matts/ surface braces

tyre pressure means a lot on the coins, dont go below 30psi.

spudboy for the man you dont need a full sized winch, a half sized winch with a pre configured 3:1 done with a snatch block and bridal combo will get you out just as well at around 2/3 the cost and it will give you incresed flexabilty, while you might only be able to self recover for say 30m youd be able to reach out over 90 to a normal sized 4x4. and sometimes that little extra is all you need to get to crawling forwards if you rig it in time. But Id suggest you invest in hydraulic, the nice thing about old PTO drive 8000lb winches is they are easy to adapt to a wider drum, you just need some suitable thick wall steel tube and rodding to remanufacture the drum and its support then build a cradle to suit, then you add a reduction box from a petrol post hole digger driven by about a 2hp motor..



I suppose the army had some pretty 'do anything to get out of a bog training ideas..

not so much as theres still a few o us around who would rather get on with doing something rather than wait around for someone else to come and do it for us.

and dont forget...

hydraulics beats mandraulics every time is as much warning as it is advice.
