Slurry tanker broken axle

[daveydiesel1]

11 ton of sh!t plus tanker....

So the tanker manufacturer is fittin a axle thats not designed for the load being put on it. Out of interest. Has any1 ever had a joskin or other european brands had axle problems? Or is it just the irish brands?

Everybody should just buy 1500 gallon tankers and travel at 18mph. Problem solved.

I could be wrong but I think all the single axle tankers are restricted in speed as the tyres are not rated to carry those loads at the higher speeds. Don't think you can get a big tyre that can do it so if you are pulling it at the higher speeds it's your own fault if it breaks. They won't fit a stronger axle if there is such a thing as there is no point as the tyres can't take it anyway!

I have nokians els steel belted radials. They are rated at 8 ton each at 50k.

I dunno why so much Irish gear gets sold around the country. I really do not.

The build of it is nothing like the European brands where they have had tri-axle tankers and serious weight/speed combinations on the road for much much longer.

I am sure the European contributors will be along to tell us what their exact regulations are and how long they have been enshrined in law.

that is a good question , as a lot come from china now, ROR were the best years ago

Just because it's from China doesn't make it sub standard. Granted there is a lot of shite comes out of there but there's also a lot of quality items too. It's all about the price.

But if ur specifying it with a comercial axle the axle should be fit to do 56mph as this is the speed a lorry does and a commercial axle is supposed to be that spec. So whos cuttin corners the axle maker or the tanker maker. They all know most farmers doin road work is now runnin 50k tractors. Whether thats legal or not is a totally different subject (a subject that am not really interested in) but non the less they need to make products thats fit to stick it and stop hidin behind some technicality that ther only "supposed" to do 30k. Would nearly bet european tanker companys will be makin stuf that can stick it

You are right but would you wont want to pay for a machine to meet european road laws.... if it says 30k max speed it could have axles made of carbon fibre that do 200mph on an F1 car but the designer has the right to put top speed on it.

What size are they?

Yes the Irish stuff is built like a tank and far stronger than European stuff for a reasonable price. Do you not recall the thread on here about a supposed premium European tanker. Or how about the joskin tankers with the weak draw bars. Or have you never seen the accident pictures involving European trailers where the flimsy draw bars are all twisted.

That was one particular manufacturer, I did not see a serious structural defect on that thread as I recall, more just generally poor build quality a somewhat different thing.

I am not convinced of this mythical Irish tank-like quality. A lot of the Irish gear seems to be exactly the same design as a smaller, single axle machine. Take the design, lengthen it, and a couple of axles and bish bash you are done.

Once you start talking about 30 tonnes at more than 40km/h you need some serious CAD software and engineering to be involved, not just be handy with a welder...

If you examine the design of many big outfits in Europe, they have similarities to the stuff used in commercial road haulage, which more than a few of them are also involved in.

Our nc has broke axle twice. Its a 2050 with a comercial adr axle. Da was talkin of changin it to a 2000 or 2250 with 1050 wheels but was wonderin what axle should we spec as dont want any more problems?

Have 150mm bpw axles here on a tandem tanker, have had bother with u bolts and the spring carriers on the bogey cracking but the axles themselves have been good

 

[The Son]

Hi spec use ROC axle made in China

ADR axles on this one

 

[Sharny dubs]

What size are they?

800 60 r34. Excellent tyres but very expensive

I think that is kinda the appeal of some brands though. For the lower end of the market it really is about putting a tank on a set of wheels with a draw bar and that's all many farmers are looking for. Second hand 50k tractors with suspension are also becoming affordable these days too, and there's going to be some consequences. People go faster not realising the mechanical stress on the machine when their suspension is absorbing it instead of the seat.

Some great equipment comes from Ireland though. I'm pretty sure the likes of Mchale and Malone have some pretty serious CAD designers and aren't just a few lads in a shed with a welder.

There lies the problem. Very expensive. Most farmers etc are buying tankers to a price. So if one manufacturer fitted these tyres they would be more expensive than the competition and wouldn't sell any.

Could it be the case that the offset of the wheel rims are wrong and are putting too much stress on the axles?
