vehicle Weights

Hi all, posted this here cos it may require some more “specialised” knowledge. :wink:

Can a rigid vehicle weighing 32.6 tonnes GVW on 3 axles and a vehicle weighing 22 tonnes GVW on 2 axles be driven on the public highway when they ARE NOT covered under any STGO licence?

Secondly, am I right in assuming that the maximum gross weight of a 3 axled vehicle (on the public highway) is 26 tonne and 18 tonne for a 2 axled vehicle?

This is not a conventional HGV but an Airport Fire Service Crash Recue Appliance.

Cheers in advance for any replies,

I would say if you can’t get a tax disc for them then no they can’t, are they going to be used on the road, or just need moving?, if they need moving just get them transported by low loader, it’ll be far less ball ache.

Hi Joe, the vehicles apparently are being driven on the public highways as part of a driver training programe.

A mate of mine works at one of the airports and they have to drive these on the main roads once or twice a year to keep their hands in so to speak.

The appliances are taxed etc as per normal , he was just concerend about the weight?

Your vehicle is not a ‘Goods Vehicle’ so the maximum weight limits do not apply. Another example would be an American truck which would be used for shows and private use.It would exceed various length limits etc, buy you would still be able to use this vehicle as its not being used as a ‘Goods Vehicle’.

The above isn’t gospel but it is my interpretation of the regs…

as someone else said, would not come under good vehicles, but probably engineering plant

mobile cranes fall into same thing, but even they have axle weight limits nowdays

Cheers for that JJ…I wasnt sure if the rules were just for goods vehicles or just vehicles in general, told him to go back to VOSA and double check.

A three axles rigid can be either 23 or 26 ton !!! If the third axle is between the drive axle and the steer axle its classed as 23 ton if the third axle is to the rear of the drive axle its 26 tons. You find the 23 ton rigid is common with chassis that have been stretched.

Hi willie_mac, I’m not sure, but I seem to remember it a bit differently than that. :confused:

IIRC, it depends on whether the suspension is “road friendly” (RF) or not, and I’m sure that the number of wheels on the “extra” axle will also influence the final authorised weight, as would the ply rating of the tyres used.
Wasn’t it 24t with steel suspension and 26t with RF suspension??

I also seem to remember that a driven axle might be allowed to carry a higher weight than a non-driven axle.
Do you have the latest info on that?

hi williemac…im sure the appliance is all wheel drive configuration, front axle only steer and runs on six bloody great super singles!! :open_mouth:

Dieseldave…the springs are metal leaf not on air, not sure of the ply rating on the tyres but the manufacturers recommendation is that they can only be driven at a max of 50mph and then only for half an hour tops, then its time to park up and let them cool down.

Its abig old beast, if I can find the spec on it I will post it up.

Cheers, bullitt.

Hi bullitt The stuff I quoted was C&U stuff as I remember it. I’m not sure where Willie’s info is from, but I’d missed the point that you’re talking about a specialised vehicle, which might not even count as a truck. I’ve got a pic of something like I think you mean and I’ll have a look to see whether I can find it. :grimacing:

I am doing this from memory !! But a 6x6 I think would be exempt from normal Construction and Use regs.

Hi willie, yes I thought the same but according to VOSA its over weight although it has a tax disc!!

Dieseldave, click the link… fire-aid-int.demon.co.uk/ffukair.htm

The red appliance is the one, its a got a 6.6 litre Detroit Diesel puttting out 700 odd horse power at full power. Can do 0-50 in 35 seconds and goes onto 65-70mph!! Sounds nice to :smiley: :smiley:

Hi bullitt, I’ve had a look at the link, and I think, like willie_mac, that would count as a “special” since it’s arguably not a truck operating under C&U regs in the normal sense.
IIRC, there are exemptions for this kind of vehicle.

Those three axle jobbies look OK, but this one from Munich airport is a real monster: :grimacing:
