One bad ADT!!!

Possibly a new truck coming from Bell???:jawdrop

I wonder how it would steer with that extra axle.

[JDOFMEMI]

Tire wear on artics is horrible with tandem axles, I can't imagine it with tri axle.

I think that looks like a photoshop job. It makes more sense to use larger tires, instead of more axles.

[ben46a]

Well the current largest offering from bell is a B50. That decal doesnt look like a chop. and the wheel locks are all in different spots...... who knows? I wouldve thought theyd put two axles under the cab first, but i suppose thatd be real hard on the hinge transferring that much weight.

It may have more than one steerable axle, would be my guess (though hardly a justification for increased O&O costs, unless they found a breakthrough).

[Squizzy246B]

The Bell website makes no mention of a B55D

Thats not a new invention...:)
Volvo made the A70 some years ago.
I know where they work, but have only found pictures of the front and not one showing the three axles behind.:mad:

U can search for them and u will find the picture attached here.

Well he said:
Hello Norway, i found this post by a fellow norwegian in another thread, pic of the Volvo A70.

Well, pierre, i made that same post.:)

The A70 was made in a small number for that mine.
The rest of them has been scrapped over the years, but there is still one left.
After they used the A70s, they went over to truck tractors and huge trailers.

Theese guys transport 15 000 000 kg pr day....in Artic conditions.:D

This truck is not new

[Mass-X]

I have a hard time seeing the justification for a quad-axle ADT. As already mentioned, tire wear would be greatly accelerated over tri-axle machines; which aren’t necessarily known for being tire friendly. Increased payload capacity would be offset by lack of production due to low travel speeds. I’d wager that the B55 won’t break 30mph, probably substantially less.

The only real benefit to 40-ton ADT’s over equal payload rigid-frames is the ability to handle rougher haul roads and go more places (climb rougher grades, maneuver rougher stockpiles). The new 770F’s are fast trucks and absolutely smoke any ADT’s out there when it comes to production.

I do believe there’s room to expand the ADT market with tri-axled machines offering 45 and 50 ton payload capacities, but I see that as being about the limit of the ADT design.

I spoke with one of the John Deere rep’s at Conexpo for almost an hour about rebadging a Bell B50 as a John Deere 500D and introducing it in the states. He said that John Deere has been contemplating doing so, but needs a deeper market than they currently feel there is, to justify getting the parts in place within the US to back any Deere 500D’s that went into customer’s hands. He stated that it would require at least an initial interest in 50 machines [sales] to justify introducing a Deere 500D.

Prior to Conexpo, there was talk that either the CAT 745 or 750 prototypes would debut at the show (unfortunately, neither was there). In talking to the ADT rep for CAT, he said that both machines are too early in the conceptual phase for them to debut at the show, if they’re even going to be introduced.

Despite the problems associated with the bigger ADT’s; increased tire wear compared to equal payload rigid-frames and lack of tire availability; I can see a market for 45 and 50 ton ADT’s. But a 55 ton machine on four axles? If you need to move that much material, invest the money in your haul road and run small rigid-frames.

[JDOFMEMI]

You are right on the money. Remember the DJB/Cat D-550? It was a 55 ton ADT, and it was a disaster. I run a number of 35 and 40 ton ADT's, and while I always like a bigger truck, I would be very carefull exceeding 40 ton size. The operating cost diffrence from the 35 ton to 40 ton is even more than the added 5 ton payload justifies.
I talked to the Moxy people at Con-expo, looking at their 50 ton version. I asked how it would do on the same size tires as a 40 tonner, when I have tire troubles on the 40 ton trucks already?????
There are also numerous drivetrain troubles on most 40 tonners that the 35 tonners only rarely experience. I could only imagine the added headaches of 4 axles, and the extra one better be steerable if you want to turn, and if you want any tire life at all.
Like you said, if you need to move that much, use a rigid frame 40 or 50 tonner.

The only advantage I see for a larger ADT is contractors, where the truck would have a higher capacity on good roads and poor, and you only can afford one fleet of trucks. Even so, you should really look at all the numbers. This then brings up the next issue for a contractor fleet. One of the selling points of the ADT over the rigid frame is ease of transport. The 40 tonners are getting pretty close to the limit of conventional lowbeds and unescorted moves. If they grow very much, then they will lose that advantage as well.
ADT's are well suited for a variety of jobs, but if you need that big production number, then the rigid frames beat them hands down, and at a much lower cost per hour due to the simplicity. Less moving parts equals less chance of breakdowns, major or minor.

That Volvo looks like a standard model with a lengthened frame and a tag axle. It does however, look like a drive axle with that planetary hub inside the wheel.

What the whole series of pictures looks like is they need an Arizona day like this one at 110 degrees F. Way too much of that white four letter word lying on the ground there.

Putting two axles up front creates it's own engineering and manufacturing problems, besides adding a lot of cost. These trucks are already maintenance intensive and costly to operate.

Artic's are not really a long distance truck unlike the rigid-frames which can handle a substantial distance. I've run the large Moxy's up to 13 miles or more one way, but we paid for that in wheel and axle seal failure. Ad to that the fact that they are not as stable as rigid-frames and they become less attractive overall. Still, they have their own special spot in earthmoving.

I'm south african, we might not think like the rest of the world, but we didn't make that beast!

Looks strong, but not like a bell. No such thing on Bell's website (confirmed).

Cool pic though.

[aocustom]

Volvo has some great older machines. Ive heard they are builing a bigger model that their A40E they have now. Will be neat

[JTL]

Why noy buy a PayHauler:Banghead. 50 ton rigid frame truck with four wheel drive!
Just think of all the mechanics you could employ!!

[Bellboy]

Taking a better look at that pic, I see that it has an interesting model number.

It calls itself the B55D, and yet the largest ADT made by Bell is only the B50D. I don't believe that it is available in America, but it is a 50 tone ADT, whether that applies to the weight, or the payload, I don't know.

The colors are off in those pictures, due to the "professional photographer" using +9000 saturation and not knowing how to white balance/manage color space *rolls eyes*

I've gone and fixed the colors in two and attached them to this post.

Yup, thats one 'dem puppies. Pretty cool, if you try not too think of how big they are, for an ADT!

WOW talk about a MASSIVE adt, thats amazing!

Just in case anyone was wondering what the cat D550 looked like....

Question is what is the advantage of the tri axle set up compared to tractor trailer combo such as this
http://www.haulmax.com/3775Tone.php
I can see the tri axle working out in a situation where there is not turning whilst loaded.

[Dayton3]

For years I never thought ADTs were that appealing but this one is a beauty.
