Hi guys

Our deefer has a non standard ally roo bar on the front. Its big and constructed from either 6mm ally plate. Its attached to each chassis rail on 4 (yes thats right) sides so a plate either side of the chassis rails and a plate top and bottom of the rails. these plates are again 6mm. The bar also has 2 recovery eyes below it in line with the chassis rails made out of 10mm plate. bolts are 2 x m12 vertically and 1 x m10 1 x m12 horizontally

It also has high lift jack points in it too.

My questions are (in the absence of pictures which i'll try and get later)

Do you think it would withstand snatching?

Do you think if there is space it would hold up to a winch being installed.

Its a very hefty allow bar.... more so than most.. so thats why im curious!

Thanks

Steve

(I am not an engineer, but) I would not trust alloy - just get a steel backing plate made up and mount the winch to it.

That way you arn't taking any chances.

mount recovery hooks to the chassis. You should never snatch from a bull bar.

I agree with flag, i wouldn't trust alloy for a recovery point.
Your best off fabricatiing them to the chassis:)

Thanks Guys...
Unfortunately i am an engineer! still wanted peoples opinions on the possibilities tho.. as its such an unusual bar..

recovery points are going to be a bit interesting as the bar will cover most of them.. and the fact that the bar has all 4 sides of the chassis covered too...

are there any off the shelf ones available?

Flagg, when you say steel backing plate do you mean a chassis mount one or a reinforcing plate to sit behind the bar inner face?

Thanks

If you plan on putting a winch on it. Maybe build a 6mm gussetted steel plate that runs behind the Al front plate and is mounted to the inside and top of each chassis rail. This can be drilled for winch and fairlead and then a rated eye bolt either side of the winch.

Even with 6mm Al I would worry about just bolting a winch to the inside, loads will stretch the front plate. And 40kg off four bolts may fatigue the holes leading to cracking. A steel backing plate would be prudent.
