tri axle hopper

Jan 18, 2016 at 10:57 AM CST
Is a triaxle hopper a good investment for someone who hauls commercially in only mn or just a waste of money? they can haul 28 ton legally with a tandem and we're wondering if it would be worth it to go to a triaxle.

I personally don't think it is worth it. I had a spread for years. And just bought a new trailer and went back to a closed tandem. Sure you can haul a little bit more. But there is other things to consider also. My empty weight went down by 2500 lbs, so now I didn't really gain that much extra cargo with the spread as I thought. A triple has 4 more tires and 2 more brakes to take care of. And when I priced a triple compared to a tandem. It was close to $10,000 more. So how long does it take just to make up the extra money to pay for that extra axle. Oh, and my fuel milage is also improving. We have lots of double doubles running around here. And they think they can make more money cuz they can haul twice as much. But once you start putting a pencil to it, bigger isn't allways better.

Ok thanks, that is kind of what we can up with too when we were pencil it out. Didn't seem to pay. Do you have a pusher axle on the tractor or are you running 5 axle?

Just a 5 axle. And don't have to worry about different weights for different states or how much to put on. Load it up to 80,000 and go.

5 axles is definitely easier hauling. We run 50' triple axle trailers and we also have a high sided tandem. If you are going long distance tandems are nice and you can buzz right down the interstate. It all depends what you want to haul. One thing I do know is we have a truck with a pusher that we run with the triple and it really doesn't pencil out to be worth it in my opinion. We have it on a 2007 Pete 379 and compared to our new Pete 389 with the same wheel base and no pusher we can only haul 25 bu of corn more with the one with the pusher. So it really depends on the truck and your specific situation. The pusher we put on our truck added about 1200lbs to the truck for empty weight.

We run tandems. 24,700 full of fuel. I've debated buying triples, but I'd only net 2,500 lbs if I was lucky. I can scale more than most guys around here that run triples as they pull them with "hoods" and weigh 30K empty. We also run primarily in KS, so multiple axle rigs don't really benefit us.

What do you run for trucks with that kind of tare weight? Are they daycabs or do they have sleepers? I'm thinking of going away from the 379 but not sure what to switch to.

'09/'10 T660 Kenworths with ISM Cummins and autoshifts. 32" Aerocab flattop sleepers and just about any lightweight option they offered, including wide base tires, fixed 5th wheel, composite springs, etc. Pulling '12 Timpte American Ag 42' hoppers with alumin king and sub, wide base w/ PSI, elect tarps and hyd traps. I've had it as low as 23,800 lbs but we wouldn't go far on fuel. Pics on our FB page if anyone needs proof.

I believe you. I can't go aluminum subframe on our trailers as we use them to pull out of the field during harvest with our old farm trucks and they just won't hold up like the steel subs do. I have been looking at going to a t-660 but haven't found what I was looking for. So I have been thinking about going to a brand new one.

We pull out of fields and off the farm with ours too, and we don't abuse our equipment either. I've had 6 Timpte's all purchased new. The first 3 had steel sub and king and gave us no trouble. The last 3 are alumin and Timpte has replaced the subframe and upper coupler assembly on 2 already. So in the long run, I don't know if the light weight is the best option. The new components are a updated design that seem to be holding up though, so time will tell.

I'm a fan of Timpte too. In our county up here in Nebraska we have to twist our trailers because our roads are crowned so bad in the middle that you can't help it. Nobody knows how to use a maintainer and they use the drags all of the time and they move everything to the middle of the road. Wilson's hold up ok too with steel sub frames but they are heavier than Timpte so I stick with them. I looked at used Wilson's last year when I was looking for a used tandem and every one that had aluminum subframe had been welded or had been replaced already and they were 2010 and newer.

I'm actually speccing a new T680 now for kicks and grins. I don't think we will get the weight down to where we are currently. Thinking about a tag axle to get close. I also went back to a big block Paccar instead of the small block Cummins, so that will add 400lbs. But I think the fuel mileage would offset that. I'm just curious as to what we can build. My current trucks with VIT, leather, and every trinket I could order, was $110K.. I'm guessing it'll be $120-130+ for a new one, coupled with possible low trade allowance, will make running my paid for equipment look like an attractive option. The one problem with speccing trucks and trailers like I did, is I will have a very limited market to sell them to. But we got what we wanted, and they have done the job well.

If I go kenworth I want one with the couch sleeper so I can strap a carseat in the back so the wife can tag along if she wishes. Can only get that in a minimum 72" sleeper so I won't be near as light as you. I also want atleast 550 hp so I have to go Cummins. I like the 680 but don't think you can get that with a couch in it. Priced a new 660 in early December with a stamped weight of 17000ish and it was $147,000 cash with no trade. He told me I would be better off selling my 2007 379 privately since it is pre-emission.

I used to strap my daughters car seat to the bed in these trucks. When I first started trucking 12 years ago I ran a 1995 T6 72" Aerocab with the sofabed. It was hea vy at 28.5, but if I ever had to wait in line, I was comfortable watching TV! Kinda miss the old truck, but at the end of the year, the extra 4k lbs payload of the new trucks makes up for it.

So comparing timpte and wilson if you had all the light weight options whose trailer would be the lightest but still the strongest in a tandem setup? And would it be comparable to a cornhusker?
Replied on Tue, Jan 19, 2016 at 07:31 AM CST
Timpte will be lighter than a Wilson spec for spec. May not be enough to make your decision but on a triple axle when I priced new and asked for manufacturers weight it was 800lbs. Timpte had 100cu ft of more volume than the Wilson. No idea how they compare to cornhusker but I have personally witnessed seeing one in the repair shop that was starting to crack in the middle of the trailer. Don't know the story behind why but I am not taking chances.
Replied on Tue, Jan 19, 2016 at 07:58 AM CST
Ok someone told me at one time the lightweight timpte was lighter than wilson but have more problems with the aluminum subframe cracking. Could someone shed some light on to whether that is true or not?
Replied on Tue, Jan 19, 2016 at 08:05 AM CST
Our build sheet says 7,700 lbs +/- 3%. Aluminum king saves 425-450 lbs and sub is 200-250 if I remember. Tractors stamp at 15,020 and 15,200. Never weighed them separate though. Yes we have had issues with these new Timpte's, but the factory and our dealer have worked well with us to try and resolve them.

Bought a 2015 Wilson a year and half ago, had a recall on the kingpin supposedly cracking, mine was ok. Haven't had any problems with it. As for the weight I have a 2006 W900L day cab full of fuel w/trailer empty is 27,000.

As a guy who has built trailers for 4.5 years and having a buddy that runs a repair shop from what I have personally witnessed I would say it is probably all a matter of luck. My buddy says he has worked on all of them. He says guys going down the highway don't have many problems but as soon as you overload them and twist and turn them that is where you run into problems. So if you are just going to run down the highway you shouldn't have to worry about it but if you are going to run overloaded out of the field at harvest, don't expect it to hold up.

I just traded for a T660 at Sahling kenworth back in October. I think you would be impressed with the Paccar engine over an ISX for the cost difference. Mine is MX13 set at 455hp/1,650TQ and it pulls a tandem axle hopper just as good if not better than the 450hp N14 I had before. So far fuel mileage has been 6-6.5 pulling a Timpte tandem axle. Full of fuel with me in the seat I weight 27,800. Truck has disc brakes, AliArc front bumper, on LP24.5's, 13 speed ultrashift and a 62" flat top. The bumper added almost 400 pounds but I felt it was a necessity. Believe stamped weight is 15,800.

Nice! I pull a 50' Timpte triple spread where I can gross 90,000 without getting in trouble. I had a 2007 Pete 379 without a pusher and had a 550 cat with an 18speed. Traded that one in for a new flattop 389 with 550cummins and swapped trucks with the old man and now have his 2007 Pete 379 with a pusher and 550 cat. Gonna drive it until I find the kenworth I want or until someone offers me enough to take the 379 off my hands. It is hard letting go of a pre-emission truck but it would make the wife happier if she could ride along on some trips. I just don't know if the 500hp paccar would satisfy me since I am used to the 550hp cat? I thought about doing a glider but I was told that in the near future more states are going to be like California and pass laws where you have to have the emissions on your truck or you won't be able to run them. It is way more expensive to add it later than to just buy a new one with it on it already. Too many ifs in today's world.

I had a 2004 freightliner Columbia. 50ish flat top. C13 with a 1994 timpte 40x66x96 spring ride. Tare 23.5 to 24. Motor sucked traded tractor for a Ravens dump. Got driver a 1997 w900l 72 aerocab stand up. His is double bunk, n14. And got a new trailer 2015 timpte 42x78x96 air ride. Tare now around 30.5. The bigger new trailer is actually lighter then the old one. Never had any complaints about timpte. The 94 had just as many miles off road as on and was always loaded from front to back.
