Thread: 110 axle load limits

AFAIK in NSW changing components does not vary the GVM or axle load limits, unless they are certified by an engineer.

Are you saying ANY spring lift needs engineering cert?

The chassis front on my Defender is the same as the standard 110 (as is the rear) the difference is the HD springs and HD hemisphere.

If you want the springs to change the axle limit or GVM then it needs an engineers cert and blue plate.

Not completely familiar with Qld but AFAIK a lift over 50mm does require engineering.

ok, so we are back to your imported 6x6 not quite the OPs vehicle or what was sold here....

Its a standard 110 that had the rear chassis cut in the centre of the rear spring hanger and 40" of RHS inserted and the back welded back on. The springs IIRC are double orange stripes and the rear axle limits the same as a standard 110. It even has a 110 VIN.

To 'legally' change the limits, you're going to need engineer certification.

However...

It's all well & good beefing up the suspension but the heavier you run the greater the chance of something failing. Do what you can to lighten the load, rather than beefing up the suspension.

My 2p.

Kelvin, I take it that was a rhetorical question in your second post.

I wouldn't be worried about 40kg over on the front axle, unless the springs were loaded/sagged to be running nose down and close to the bump stops.

If it did looked sus, besides how bad it will ride, you might get pulled over and put on the scales. Then I don't know what tolerance might be applied (3.333% over) and could depend on how good a day they are having.

Dianna, I have never yet seen seen Land Rover axle ratings where the GVM is not less than the sum of axle ratings. GVM is not calculated by summing the axle ratings.

Depending on how the load is distributed, you can reach an axle rating before reaching GVM, or you can reach GVM before reaching either axle rating.

I agree the springs ratings are increased to increase the axle rating, but it doesn't mean that there are no structural changes to the axle or other areas.

IMHO it is irrefutable that the Heavy Duty Salisbury is strengthened for use in the HD option for 110's, as for the 130.

However I am yet to find that the rover front axle had any structural changes for the increased rating. Since the increase in rating for the front axle is much less than for the rear, you statement is probably correct, but it does read as though you think the rear axle housing is also unchanged.

Hi John

No I was only speaking about the front axle, the topic of the thread. Also relating it back to my chassis front. (the comments about the rear of mine was surprise that the front would have the HD specs and the rear standard*)

My thoughts on the matter were/are that if Weeds were to have the 130/110 HD equivalent springs and the HD diff hemisphere (or maxidrive/air locker etc), there is no reason that he couldn't have the front end specs uprated plus blue mod plate and therefore avoid any problems with the mermaids.

* glad it only has the lower rear specs, because I'm trying to have the GVM down rated to avoid the National Heavy Vehicle charges on the rego.

nope serious question as I have a weigh bridge at work.........did axle weights and thought wonder what the max. is for each axle

a lot of people across the internet state they know the weights of their rigs/trailer etc but I really wonder how many actually take their rigs across weigh bridges
