Hey folks, Just wondering if anyone knows what this truck would weigh empty?
It’s an ERF ECT, think it’s something along the lines of 370hp from a ■■■■■■■ engine. It’s a flat bed, high roof and it’s got a HIAB on the back of it plus it’s a wagon drag so it’s got the coupling on the back too. Any Ideas? it’s only a 4 wheeler. I’m told the max weight for that plus the tri ax trailers we pull are 40t. doesn’t 370 sound a little under powered for that weight?
try pulling 40tns with 250–280bhp, we stil run the 280
Man .s just becuse oF the low tare ;MORE WEIGHT CARRIED
means more profit for the employer,
Why don’t you take it to a weighbridge and get it weighed?? No good anyone on here guessing for you, this wouldn’t help you if you got caught being overweight and you explaining to VOSA that you were told by someone on here!!! 
370 is a little below what you really want.
Not sure m8 but i would as matter of fact get it on a Public Weighbridge and find out before some numpty of a Tm overloads you .
I know it dont help with you question but for your pice of mind and license, it would be my first step ,and has been in the past . theres plenty about
if you look at the vosa plate usually positioned in the passenger seat footwell
it should give you all the info you need . and if youre not sure just look at the plates on the wagon and the trailer find the gross weight of both then run them across a weighbridge empty . thats your net weight you then know
i can load 22 tonne etc to get your gross /max weight but when loading you must make sure the wagon and trailer are within there limits . think 40 tons
is a bit excessive on the combination you quated (bad spelling again)
six legger ok but a four wheeler 
A two axle truck, pulling a three axle trailer should be good for 40t gross.
Check the MOT plates on your wagon and trailer to be sure.
You want to get on a weigh bridge and find out what you weigh empty.
Then you’ll know how much you can load.
A few years ago, 370 was what most drivers dreamed of.
You’ll do fine on the flat but you’ll be a bit slow on the hills, that’s life.
Learn to live with it.
The trailer is a tri ax low profile tyres and I’ve been told to expect the rims of the front axle to near touch the ground when doing tight turns lol. The unit only takes about 5t of a load so I’m sure I wouldn’t be over with that. Mind you, the thing does love to run on a bit on down hills where other trucks I’ve driven don’t as much. Perhaps that’s the gearing keeping the revs to sub 1,500 rpm when cruising at 54?
Thanks for the replys
I’d love 370, don’t think I’ve got 37 in this shed… new job starting monday week anyway…
Hi steve your truck weight depends on what size of crane is fitted.
A mate of mine drives a 4 wheeler cf daf with a 23 mt ton crane and 320 horses, that truck weighs in at 12 ton empty.
As the other guys have said you should run it over a set of scales.
The easiest in our area is just of the A9 at stirling you can go in there any time , just pull up short of the scales jump out press the button below the screen then drive slowly forward , as you drive over. the screen will show your axle weights, just add the 2 weights together to give you your unladen weight.
Not to sure about running 40 tons with a 4 wheeler even with a 3 axle drag. I would have thought you would need a 6 wheeler for that kind of gross.
I’ve just moved on to artics from wagon n drag, 6 weeks ago, I fancied a change 
I had A 56 plate 75cf 6 wheeler with A twin axle trailer, This was plated
for 40t.
Trouble was, sat behind the cab is A fassi 420 crane with 4 hydraulic extensions.
The unladen weight WITHOUT the trailer was 17 1/4 t 
That’s got A 310 engine in it 
YEP, very slow

Why?
6 axles, on air are required for 44t.
5 axles, on air are required for 40t
as a general rule.
Either an artic or a wagon and drag, it makes little difference, provided the wagon is intended to do the job.

I used to pull 44t with a 360 DAF, was OK!
Went better down hill then up though, used to be loads of 2500 DAFs and F7s etc at 38t

Not sure if the front axle on the unit is air, think it’s just springs. There certainly isn’t a button on the remote control to lift and lower it

They normally aren’t and you don’t need air on any of the others. (unless the goal posts have been moved) We set up with air on the rear axle on the unit, full air on the trailer when 40t came in. Only to find a few weeks later that anyone could run at 40t, as long as the Unit was plated for it.

My six wheel CF with a 12 t/m Atlas on it weighs in at 12 tonnes unladen. It’s not a prime mover either just a rigid and that’s got the 310 in it too.
Sounds like they got excited ordering the drawbar coupling and forgot the bigger engine!

Forgot the bigger engine When I asked as to why I couldn’t have got A 380,
I was told the 310 IS A big engine, because their rigids normally get 270’s

That’s why I said “as a general rule”.
Very few wagons have air suspended front axles.
To run at 44t on 6, (or 40t on 5) they have to have ‘road friendly’ suspension though. Road friendly was initially considered to mean air.
Most wagons are set up with air on the drive and second axles (if it’s needed), steel on the front and air on the trailer. It’s a very convenient suspension system, although slightly heavier than steel (in a comparable set up).
The main point was that a 40t gross weight rig only needs 5 axles, not 6, whether its an artic or a wagon and drag.
i would take it to a weight bridge and just find out
