Thread: 6WD Chassis Drawings

the hand book that been updated now shows--
HR 3 or more axles over 8T GVM .
MR over 8T GVM only 2 axles.

LR up to 8ton GVM or over 12 seats with no mention of axles and that has changed since i did my lience.
I ask first or get it in writing.if that the case you can drive in and get an up grade with a van from a CAR lience.

the reason i looked was the GVW AND GTM.on the plate-GTM is towing mass and not counted.unless the trailer cant use the tow bar or be called a 5th wheel.

NSW police have been booking people for driving a backhoe on C lience.with a backhoe ticket.the complience officer insist we are legal.
the argument is that it in the book states for C up to 4.5TGVM ,any tractor based implement.
the discusion at work is a grader is 3 axle and 16T+ and only requires C lience-our roller is similar wieght but is it a tractor based implament?
no other qualification is required for a roller/grader.

The HR licence is any rigid vehicle (including bendy buses) over 4.5 tonne with 3 or more axles. If the GVM is less than 4.5 tonne the 3 axles is irrelevant.

The issue about 8 tonne in the heavy vehicle licences, is not a minimum but a maximum. A "LR" class is any rigid vehicle with GVM from 4.5 tonne to 8 tonne; a "MR" class is any vehicle with only 2 axles and GVM 4.5 tonne to 15 tonne depending on tyres on the drive. A "HR" class licence is any rigid vehicle with a minimum GVM 4.5 tonne and 2 or more axles with a upper limit for GVM exceeding 8 tonne determined by Heavy vehicle mass regulations, generally 2 axles 15 tonne, 3 axles 22 tonne, 4 axles 26 tonne according to publications such as http://www.rta.nsw.gov.au/heavyvehic...h-mass0706.pdf

A fifth wheel type trailer is also irrelevant if the GVM of the tow vehicle is less than 4.5 tonne and the trailer within the GCM or Gross Train Weight of the tow vehicle.

Even though the grader is a tractor based implement at 16 tonne GVM it would be out of the "C" class licence and very much in the "HR" class licence. The police would be correct to book the driver with a "C" licence.

Hi Diana,
While I know that the Vic regs are of little relevance to you, but I thought that we now had national heavy vehicle regs.

The "Victorian Bus and Truck Drivers Handbook" issued by Vicroads says

"Light Rigid (LR)
A vehicle greater than 4.5 tonnes but no greater than 8 tonnes g.v.m. or seats more than 12 people (including the driver).

Medium Rigid (MR)
Any 2 axle rigid vehicle greater than 8 tonnes g.v.m.

Heavy Rigid (HR)
A vehicle 8 tonnes g.v.m. and above with 3 or more axles."

From that a 6X6 Landy at 4.7 Tonnes g.v.m. is a light rigid.
or have it de-rated by 201 KG and then it's a car licence, just like my 130 at 3.5 tonnes towing a 4.0 tonne trailer.

The Vic roads are actually the same.

All vehicles once they are 4.5 tonne or greater GVM or greater are governed by heavy vehicle regulations.

In NSW and Vic there are both weight and axle restrictions.

If a vehicle has 2 axles and a GVM 4.5 tonne or greater:

1. But less than 8 tonne = Light Rigid licence. (LR)
2. but a GVM 8 tonne or greater = Medium Rigid licence (MR) (the max is 15 tonne because that is the maximum for a 2 axle rigid vehicle)

If a vehicle has a GVM greater than 4.5 tonne and 3 or more axles = Heavy Rigid licence (HR).

Hi Diana,
Interestingly the learners guide that is issued (well you have to buy it) when training for a heavy licance in Victoria, that I quoted above makes no mention of axle numbers in the LR category, and I would have happily driven a sub 8 tonne 3 or more axle vehicle.

I will try and get to Vicroads in the next few days and ask, I'll report back with what they say.

Hi Tony

I have checked the Vic Legislation and you are correct, in fact I thought I deleted the above post last night because of checking the legislation, but because of the slowness of the Telstra router up near Incisor's place the delete command didn't get there.

It is the same with the wording in the NSW Legislation, however you and I both know it's not necessarily what's in the Law, it's what the coppa at the side of the road believes is the Law that will get you the ticket.

The 16 tonne GVM grader still still needs an HR licence, but in reality I don't really care what class licence one needs because I have an HR and have had for 30 years.

Good to know some photographic evidence of the old 6x6 still survives.
I think i've probably reached the stage where I've come to the limit of development of my 4x4 from a cross country ability perspective, and the only reason I won't convert it to 6x6,aside from a relative lack of enthusiasm, is that I no longer have the facilities to make another pair of portal boxes and drive splitter for the third axle.
Re the Perentie 6x6 bogie suspension. Articulation and cross country performance could probably have been improved with a so called 6 rod inverted, centrally pivoted leaf suspension. But then again,with such a relatively long primary wheelbase of 130''? and rear overhang on 7.50x16'' tyres, the vehicle will never be a mountain goat anyway.

Hi Bill,
I also found this article of your 6x6 on another forum.

Bill Van Snorkle's 6x6 Land Rover Series

It makes for some great reading, I wish I was around to see it. Is this the one still in bits in your paddock?


Anyway, sorry for hi-jacking. Unfortunately I don't have any chassis drawings of the 6wd.

Regards,
Sam

Came across an article(originally published in Autocar 30 Jan.1969) in a Brooklands book called "Land Rover 1948-1973" about building a six wheel drive L/R. Send me a PM if you would like the article.
