Been given an old Warn winch that came off an old 413 Zuk 7 or 8000lb unit that only needs a new solenoid to run...... will know more when I get home

I’d have the rear winch mounted mainly for pulling backwards in that case.... with an option to route the rope back over the body up to the top corners of the cab. Will Warne had a neat loop in each top corner above the cab. Obviously big enough for the hook to go through, they joined I think the backstay and the main hoop.

I used an 8000lb winch on the front of 45 at Ladoga so that would be perfect. The ibex has a centre mounted 9000lb running through the vector system (worth looking at) to both rear and front.

LRF that is what I was thinking, mounting it just infront of the rear hook with a roller fairlead, above  the hook and use the shock brace bar to mount another roller fairlead above the winch and put some pipe (or similar style) fairleads in each corner of the B pillar and either make all the fairleads able to fit the hook or do some sort of simple release for the hook so I can thread the end of the line through 

Mike I'm surprised that was all you were running, the vid's of that event are serious winch comp stuff.... I've never heard of a vector system is this where you give it enough length between the last failead and the drum that it self spools, this is what I'm trying to with the front winch

The front winch is going to be rather large, both in width of the PTO unit and the double electric drive and toothed belt setup going up and forward above it. trying to run this unit as a rear mount would be a  bit of a sqweeze but not impossible, the reasons I want it upfront is part of our winch challenge is winch walls so I want a forward weight bias I'm aiming at about 60-65% forward to help with climbing.... the second reason is in a comp if I brake the line behind the front fairlead in a stage you'd give up lol having  the motor between us is a real space challenge adding a winch line either a tube that is an A$$ to thread or a heap of fairleads and have to pull covers and climb around hot stuff..... doing this in a bog or under muddy water just an't gona happen lol ..... where as with the winch mounted infront of the motor I won't have any hot areas or moving parts of the motor to work around, the bonnet I can lean up against the cab and I have one fairlead to fit it through... I might even be able to do it by braille in muddy water lol 

I've done a few mid mount winches and used them for a while now and I always set them up so that I could either pull out a bite or pull the rear pully out and winch a 2 to 1 pull, but the reality is in all the yrs I've been 4wd'ing I'be only ever used this a couple of times...... if its dodgy enough you don't want to winch forward, your the first truck in and you should have walked it first lol but there is someone behind you who can snatch you or winch you back 

My thinking is this.....For competition  I'm building the truck so it can drive or launch at alot of the stuff others are winching on, this means I'm going to end up in places I might not like lol or roll/crash if I've got a winch that can put me back on my wheels I loose time on one stage instead of a DNF and any stages I manage to drive I make a big win on the times

he Ibex Vector system uses a mid-mounted winch, facing rear. The rope then goes backwards to the rear of the car, round a pulley and then out of the front of the car in the 'normal' fashion. That way you can use the single winch at either end of the car.

Regarding self spooling - I looked at this in the past for a centre mounted rear winch with a rear fairlead on a 90. To get the correct fleet angle (technical term :i-m_so_happy:) I think the winch had to be something like 15 feet from the fairlead! :D:D

 

If you search the forum for "fleet angle" there are a few references to enjoy.....

Gidday Guys 

I'm after some input from some of the English/Euro winch comp guys......  I intend to use this for winch comps here in NZ, more for the teams events than the full on winch comp's as they are more about the fun of it than the competitive side 

Now our winch comp stuff is all about dragging yourself through or up stuff here, there isn't much of the "use the winch to traverse" stuff that I've seen on UTube so up front I plan on running a twin electric motor driven pto winch (still working on design and parts list lol) 

But what I'm thinking about is a second rear/mid mounted small electric winch, say a 5000lb... enough that it could pull it back onto its wheels in the case of a roll over or using a block drag its self backwards..... I just don't know if its worthwhile, next what size..... is there a big/small loss of pulling power due to friction pulling around fairleads on the corners of the cage ?  What sort of fairleads are you guys running etc 

 

Hi mate. 

I co-drive (Winch bitch) in Ultra 4, so I may be of use. 

What we find we most commonly use (other than forward) is a direct backwards pull. But in certain situations we use the cage to pull sideways from near the main hoop etc. 

As a result we design the frames to incorporate strategic tubes and tube loops to throw the hook through and run round corners as rigging up pulleys takes too much time*. That is most commonly when winch ropes fail, so there must be a noticable increase in drag when pulling round the tube, but due to the spec of both the winch and the rope it is relatively uncommon these days. I'd definitely recommend over speccing both the winch and the rope here. 

With that setup we never really opt for an additional center winch. The additional weight and most importantly space penalty isn't worth it.

 

*I won't teach granny to suck eggs about required structure and surface smoothness*

 

It's nice to see some actual design time in your bracketry too!

I was quoted 1.2m which is a little less than mine. However mine spools on and off with no problem (just as well as the winch is hidden under the second row seats). 

As Ross says mid mount winch facing backwards round a pulley in the rear crossmember (foers use a snatch block but I wanted a fixed pulley). From there to another pulley mounted in the chassis, then through a tube to the front. So a slightly offset single line pull at the front and in my case a snatch block is added at the back for a double line rear pull. There are various other funky things you can do with it for instance cable car and side pull. It's a good system but not best suited for comps.

Thanks Bisbosh I'll have a search tonight, I didn't know the term for it...... here most people seem to think 1.1m is the magic number, My thinking is based on using 9-32mm wire rope for logging. The shape of the wire will help it lay (why I have wire on my club toy because the guy who built it set it up so it can't be seen).... plasma crosses over its self alot easier because it doesn't have the same form, the deal for me is to reduce the severity of the bunching and I always build my winches so they can be seen. this one is going to be a bugger down infront of the motor but a good trick i found so long as your clear of hot air is a reversing cam and screen and I may have to set one up with the front winch 

Mikey thanks for the complement lol thats just me I over think every thing I do on my stuff even simple tabs, but just for the books I'm not a granny I'm a sort of grandad to one of my foster boys lol. I'd love to do what you guys have done with running around the cage but.... the whole idea for this truck is to have it look like a series landy and that front end isn't going to allow me to do that. As for overkill I agree the rope is going to be 12mm plasma and the winch is a Toyota 70 series pto winch with a taller drum (to deal with the bunching) air ram on the dog clutch for free spool, I will be running the worm gear so no need of a brake (I have a winch that was setup for competition that has steel worm gears and reinforced end plates on worm gear shaft to stop it screwing the shaft past the gear, this will be driven by a wide toothed belt assembly that I can change the gearsets to match conditions, some of our comps are bonnet deep thick mud some are greasy hills, the belt will run to a twin 12v motor set that will be run by a control box so I can run 12V or 24V and series or parallel on the motors and motors and belt box will be piped into the air system so I have positive pressure to stop/limit the mud getting into them....... mmmm did I mention I over think things lol and yes this is kinda the other way from the rest of the truck which is about light weight minimal, then I have a monster of a winch lol my goal is to give the god winch boys a run for there money

Mike thats the common theme over here I prefer rollers as I've seen major dramas with tubes that have worn and catch/cut the rope.... most of the central N island is pumice and that stuff wears at everything!  Tell me have you had any issues with the tube filling with mud and making it real hard to pull out on free spool ?

I run plasma on mine so it pretty much fills the tube. TSD's ibex has been on the road a lot longer than mine. Tube wear doesn't seem to be a problem but it's at least 2mm wall probably 3mm. He has had one or two issues with mud in the tube but only when left to dry for a few weeks :ph34r:. The tube run on mine is quite long (118" wheelbase) so freespool doesn't work that well anyway but it's fine winching out if a little slower.

Just a quick one on running through tube. It works fine for casual use, we ran it for 1 season on the Tomcat and it really affected the drag on freespool, so much so that I had to get james to tap out a lot of the time. It also packs with mud if you're ploughing dirt banks on approach, something to consider. 

If you keep it as straight as possible it would probably be fine. bends here are not so good purely because of the amount of contact between rope and the tube side.

The ibex tube is straight which will help. I agree that freespool is compromised a little.

Thanks guys you've backed up what I've seen here in NZ, most run the pulley and fairleads for the reasons you've stated 

Nearly finished the rear battery box, and I was looking at it thinking that the front winch is going to be heavy enough by its self up front, maybe I should put both batteries in the back so ......

Bugger!..... if only I'd thought of this a bit sooner hmmmm might have to tweek things lol
