towing engineering

[rfurzer]

I'm sorting out a solution for the towing question and will ask an engineer to look at whether the "with trailer brakes" 3500kg rating for the standard 110 can be applied in a certified way.

I want to be able to use a towbar at a reasonable height and have seen a few potential solutions. Clearly departure angles will be affected but perhaps a removeable receiver type would be a reasonable compromise.

If something similar to this 130 towbar (see pic) were to be available as a properly engineered unit, how much interest would there be?

[Dervish]

I imagine there would be plenty of interest, myself included.

I'm half a chance of buying a Perentie next year, so if that happens, then yes, I would be interested, but can I ask if this is just for an engineered towbar, or is there going to be some sort of engineering approval for the vehicle? That is after all the stumbling block, and not the tow bar itself as such as I understand it?

Do you actual need 3.5t towing capacity ?

[Homestar]

Would be handy to have better tha the 1.7 tonnes or whatever it is now. Can't even tow 2 tonnes with them legally.

1. There is a cloud of confusion about the vehicle itself.

Firstly, the rear chassis is made of 125x50 6mm thick RHS vs 2mm thick section on a civvy 110 so it seems prima facie to be built like a masonry outhouse.

Secondly, the reason that the thing is "limited" to 1250kg relates more to the military's desired use and the lack of trailer brake equipment than to real capability.

Thirdly, the authorities seem keen to pigeon-hole us into the nearest NVD they can find - usually a defender - clearly a different beast but conveniently recognised to have a 3.5t capacity.

I plan to ask an engineer to sort this out as part of another project (seats, body mods etc).

2.I do want to be able tow up to 3.5t in the form of a dirty great horse float with a 3.5ATM. The old Stage 1 coped fine with this (horses like it slow)

Good luck in the process, I guess it will come down to $$$'s

Personally I would have purchased a car that could toe what I wanted without mods or approvals.

[Homestar]

But that would be no fun Weeds, and not a Perentie... :D

Common sense to me.........

Duck 1250 wouldn't even tow my HCPU trailer.

Fit for purpose come to mind......

Ever heard of the story were an airport has been in place for years than suburbia creeps up and suddenly it's the airports problem........

Personally I wouldn't bother with the legalities knowing what BS you are coming up against. I just modified a Nissan patrol ute towbar and fitted it to the 6x6 so I can tow my 7M Sharkcat on the odd occasion I want to these days. It's overengineered for what it is so very unlikely to fail and cause any problems. The Hayman Reece hitch and towball are both rated for 3.5T.

Do you have a Perentie? No? Then why are you in here being so negative?

I will be interested assuming if it has Aussie compliance it will be accepted in NZ.

Just something to note is that the Perentie does not have the rear sway bar installed like the civilian ones do.
An Engineer may want that re-installed to certify a full 3.5T load.

Does it really make that much difference to towing? Isn't all the extra sideways stress very low on the chassis; the body wouldn't roll much more than normal.?.?

I doubt it. In the Tdi era many Defenders didn't leave the factory with a sway bar installed, not sure how common it is now.

Irrespective, there's nowhere to install a sway bar on a Perentie anyway.

What are the chain attachment points like?

Like Brian (bearman), a mate and I have put certification in the too hard basket and will be going it alone, so to speak.
Having investigated a few designs like the '110 Garthon Motors adjustable height vertical reciever', another vertical receiver design and the varieties of tongues, recievers and mounting plates available, we will probably settle on getting our own designed mounting plate fabbed.

I noticed that so far, to my knowledge, nobody has mentioned this Rovers North attachment ...

Unfortunately, I decided that freight cost would be prohibitive and didn't follow up seeking some of the dimensions, in particular, the distance from the lower hole center down to the top of the angle iron. Also, relative to the Perentie, how far the receiver extends forward into the spare tyre space, as from looking at the pic, it would appear to be too far.

Really? Looking at mine, it appears all the mounting holes are still there, you just need to bolt it on.

If you're talking Perentie, then, bolt it to what? The mounting points on the diff are there, but the chassis rails aren't where you would normally mount the defender bar as they are around a total of 15cm more outboard than the standard defender rails. This was done to accommodate the spare wheel between the rails, which would have been impossible, with the bar preventing the wheel from fitting.
