Has anyone mounted an internal winch? I am having a think about mounting a winch in the centre behind the 2 front seats (would put in a roll cage and probably mount it on a plate off that as well as through the floor to something) and wondered if anyone has done a similar set up?

Obviously safety is important (would not like it ripping out and trying to push past me on its way through the engine bay!) so thats why I thought doing a full cage and mounting it off that would be best.

Also how is the rope run? is it ok to bend up some tube for it to run through and have it exit out the front where I want it? The only problems I see are:

1. How many bends I will need to run the rope through to get it to exit out the front.
2. It would appear it will need to route under the motor and so its open to the tube getting bent/pinched from rocks.

Those are my only 2 concerns at this point but perhaps others have some other information on this kind of set up.

I have a Runva 9500lb winch its a good winch but that size is fairly heavy and I would like to lighten up the rig. My original plan was that on the front and a smaller lighter winch on the rear bar so if the center mount idea does not work out I will look into that option again.

I'd be to worried about it flying off :laugh: But what is the idea of having an internal winch? Is it to put the weight in the middle or a performance thing?

What you're looking at is effectively a home brew version of the foers vector system patented on ibex vehicles. In essence what you do is mount the winch in the middle of the car and send the line centrally to the back where it feeds over a demountable snatch pulley so that you can extend what amounts to a double line to pull backwards. From there it goes forward on which ever side of the chassis has the least obstructed path to the front. Once there the idea is to either do a straight single line pull set to one side or again use a snatch block to achieve a double line. Look it up on the ibex Web pages they explain it better than I have.

I see no reason why you'd want to make is complicated as the vector system. Also, the fuel-tank might be in the way.

If you want a centre-mounted winch, you need to have i attached to the chassis in some way. It is the only right way of doing it. But why?

The Runva 9500 lb winch is not heavier than other 9500 lb lowmount winches. Perhaps put in synthetic rope first? Then you'll loose about 10 kg's compared to wire rope.

I do have the dyneema rope on the winch so its pretty much as light as I can get it. Basically I wheel solo alot in some very difficult places. there have been more then a few times ive needed to winch back out the way I came but with no ability to do so.

My original idea was to mount a smaller lighter winch in the rear bar as back up, but its effectivly more weight, more wiring etc and that winch would not be as good as the Runva - and no way am I mounting 2 of those.

The other reason is I like the approach angle of the Jimny without the winch bar on the front, that way I can make some smaller lighter bar for the front and have better approach angle.

Then there is the benefit of putting the weight low and centred in the car.

My idea for mounting was to run a roll cage through the floor direct to the chassis, then make the winch bracket mounted centrally off the rollcage behind the 2 front seats. That way it is mounted to the chassis and up in the car where I can get to it.

You need to mount the winch directly to the chassis. Not on a rollcage. It is not strong enough for heavy pulls, and you risk bending and breaking stuff, or even getting hurt.

What winch bumper do you have?

I have a ORA HD winch bumper fitted with a Warn 8274, and have trouble with approach angle.
