Thread: Ex army Mack 6x6 trucks.

and as for overweight.

the civvy spec is for 20t on the tray, the military is 10T.....

which is why we put 13t APC's on top of them.

No civvy truck in 6x4 or 6x6 will be able to carry a payload of 20 tonne. To do this the tare weight of the vehicle would be 2.5 tonne. Also can anyone tell me the tare weight of the front axle.

remember the truck wasn't originally designed with Australian compliance in mind.....

or try this for a better example

the F88 is more than capapble of putting 30 rounds of 5.56 into a person at 30 m in 10 seconds. Its just not legal to do that.

or for a slightly less psycho version

the veyron can do 300Kph on the open road. Its just not legal to do that either.

Legally or physically? There is a difference.

Legally no, physically yes it's easily possible, but regardless of any weight laws, macks own gvm is 24.3 ton..no doubt the truck would operate with a higher gvm but it may not stop or go so well!! If any truck could handle a load these are it..totally over engineered. I have a western star truck that is rated to 120ton(GCM) but the drivetrain on these macks appears to be a lot more substantial..

I'm getting more and more confused, the compliance plate on all the Macks suggest the GVM is 24340 kg



Yet the blue slip says 25900 kg http://res3.graysonline.com/handlers/attachmenthandler.ashx't=sh&id=3624053&filename=NS W+Brown+Slip.pdf or has the GVM been upgraded since the airbag suspension was fitted?

Lets say I own an overseas company that makes trucks and I make a truck that can take 20T on the tray and weighs 12t. GVM 32T

Australian rules say that the class of truck I'm building has a maximum GVM of 25T if I want to road register it and because of a combination of company reputation and this particular trucks capabilities and reliability the market will support this truck with a reduced payload.

As the manufacturer do I completely redesign the truck to comply with Australian rules OR do I just accept the free over engineering Its going to get by selling the same truck with a naffly little ally plate riveted on that says

Made to comply to australian standards, GVM 25T

I think (from memory) one of the tanker models has a maximum weight plate on it for full tanks that is higher than the GVM on the ADR plate so they were never able to fill the tanks and legally drive on the road.

I also recall some of the dumps that had the built in load measuring gear had 3 markings on it off road, on highway and design limit at 8 10 and something much higher in the vicinity of 15T

the slip is also wrong because they are fitted with back engines not cummins

Hi Dave

Thats whats so frustrating, the plate says one thing (24.340), the brown slip says another (25.900) and the RTA says a third (22.500), the Brown slip goes to the RTA and I drive down the road with the tare + payload at 25.900 believing what I bought from the Government.

Who is going to pay the fine and get the points when the mermaids book me for being overmass? I will!!
