Thread: Tow bar fitting

Oh and before anyone comments I havent towed more than 750kg with my Perentie and wont until I am happy its legal!

You're right. Those differences will probably have little effect on the GVM but appears to have a significant impact on what it can tow.
Don't get confused between GVM, GTM, ATM and GCM.

It is an Australian Army handbook.
I have a paper copy. I don't know where an electronic copy is.

Thanks Mick, that's OK I am only looking for manufacturer documentation (and I havent found any yet, but in NSW the authorities have a formula to cope with that).

And I know my GVM's, GCM's, GTM's and ATM's don't worry.

I don't think the "manufacturer" data will exist. These were custom built Landrovers for the ADF.

What is theis formula the NSW authorities have? It has been demonstrated on this forum that the 6x6 is quite capable of moving heavy loads. I intend to get the engineering on my 6x6 to re-rate the towing capacity to as much as I can get.

I dont think it does either. I just want to get as close to know it does as possible. In NSW if manufacturer info is unknown then max allowable tow is 1.5 x the unladen mass of the tow vehicle i.e. for my FFR 2250kg(from memory - but that is army documentation - probably should get a weigh bridge certificate) x 1.5 = 3375kg

I think I have said this before.

How interesting! So, my 6x6 could tow 5.97 tonnes. That gives a GCM of 11570 kg, Over 11 tonnes! Should be a doddle getting the 4.5 tonnes I want.
The book I have states the axle weights are 1350kg front and 1950kg rear so that is 3300kg GVM. 1250kg plus 1000kg for 2250kg tare.

Guys
According to the operators manual for the 110 6x6 (civilian), the GCM is 7050kg, which is the same for all 110 variants with the Isuzu engine.
As far as I can see the civilian 6x6 is identical to the military one at least at the towing end.
I can't see an increase in GVM beyond 7050kg being allowed without an engineers certificate, and any engineer will want to see some concrete information from the manufacturer, which basically doesn't exist.
The only legal way to tow big loads is to reduce the tare weight.
Also as far as I can see there are no figures on permissible ball weight.

Yeah but I think those figures are only going to apply to a vehicle with GVM of less 4.5t. Not a truck!
