Title: Mobile winch
Post by: Bullant4x4 on July 28, 2014, 06:44:29 PM
Does anyone have or use a full size mobile winch ie Runva 9500 etc? I am wanting to make a mobile winch that I can attach on the back of the Patrol or either end of the CT.

I was thinking in mounting it as a tow hitch kind of setup, so that way when we get stuck I can winch from the back of the Patrol or either way on the CT, just depends on how bad I f**k up :)

Cheers
Ant

We have warn 9500 pound winches in cradles that mount in hayman Reese style recievers, with Anderson plugs.I have not used one yet. ;D

Tigerz11, an plenty of others sell a cradle that goes into a hitch receiver.

Think about how you are going to get power to it.
Winch drawers a lot of power, companies like warn etc.. Have 350amp cables etc... To get power to wher you need it.

Gets pretty expensive, quickly, buying cable like that though...

I have 6b&s run all thru the interior of the vehicle and another line along the chassis to an Anderson plug at the back. I was hoping that would cover it?

Nope, you'll need some welding cable at a minimum, winches can draw 500A on the top wrap.

Get onto a cable calculator and check the length / amp drawer (Redarc have one on there site)

All 6B&S is going to keep you warm on a cold day, maybe provide a dull orange low at night.

Need 2/0B&S as a minimum.
Double insulated heavy duty welding cable is probably better if you can get it.
Make sure you check the rating on the cable back against the manufacturer.
Most 9500lb winches will want 300+ amps under load, 6B&S only does about 140amp on a 1 metre run, you'll need 10-14 metres (got add there & back).

What if you already have a 2nd battery in the camper or the back of the vehicle ?  (wherever the winch is)

Obviously it's going to flatten the battery fairly quickly but since alternators can probably only supply 50-100A typically so 300+A is going to flatten a starter battery in a fairly short time too.

(If you have a fully charged 100AH battery in the back, that would supply 300A for a few minutes ... should be enough.)
Just thinking another battery is probably cheaper than 10m of heavy cable provided you have somewhere to put it.

Ok, under the bonnet I have 85ah & 106ah. So the 6b&s that runs inside the vehicle I connect up to the other106ah battery that is incorporated into the rear draws.

From this battery (rear draws) I run a 2 metre run of 2b&s to an external point mounted on the rear bar.

If looking at 240/415volt type cable I would be using 95mm2 flexible cable (low impedance)

For 12 volt, you need lots & lots of small strands of copper.

240 volt, uses thicker strands and less of them - useless for high amperage DC.

I'm sure that some of the more knowledgable auto-electrical guys can explain it better.

theres a place in Qld that supplies a rear bar for the GU patrol with a proper permanent winch mount on it (like on a front mount).. so it can be done, would I bother? no

for how often you *might* use it, just get a Tirfor.

Already got a kaymar rear bar and looking to save on space and have something mounted external (Tirfor will take up internal space). Also want it independent just incase I have to drag out the CT solo, or winch it thru areas from behind the Patrol.

Can't find anyone that can take a few years off to travel around Australia. I'm sure we will meet up with others heading the same way. Got m8s that plan to meet up for parts of the trip.

You wont find something off the shelf that mounts external front and rear and that will stay there mounted for travelling and be portable enough to move to the rear.
If you have a trailer, get the tirfor and put it in the trailer, they wont take up that much space.

I don't know if I explained wrong but this is what I was thinking.

I will have a 12000 Runva on the front bullbar. Then I was thinking in having a spare (9500) for the rear tow hitch and CT. Also have two points (front and rear) added on the CT if ever I need to use them.

Here is a pic of what will work, so I have been told and I will leave it in one of the points on the CT to carry.

Might be a stupid idea? Does anyone have a similar setup?

This way I can winch any which way if need be (from either vehicle) if no one is around to help.

At least with all the comments I've worked out the power I need to connect up, as I never considered it.

yup, that's the exact thing I was thinking you meant...
I don't like your chances of it being legal having that hanging out the back of a trailer.

I have seen bike carriers hanging off the back of camper trailers......

I know a guy that made his own portable cradle, not sure if he has ever used it but he reckons it would be a hell of a lot easier than a tirfor........it is just him and his wife, pretty sure it was secured the the rear footwell
