Being from the east I rarely see the 3x3x3 and 2x2x2 west coast lowboys. But last night I was looking at a picture of one and was wondering.... As you add jeeps and stingers to those trailers to make them 3x3x3's does the driver have to have doubles or triples endorsements or is it considered one trailer?
Todd
Yes, you are required to have doubles and triples. Up untill a few years ago, this law was rarely enforced, but as these trailers have become more common, it is highly enforced now. For many years it was a matter of how the law was interpreted, but not anymore. Same with a tillerman on a large trailer. It is now a federal requirement that ANY steer man operating a steerable trailer, must have a CDL. No doubles or triples required yet, but I ddon't see that being more than a few years out.

Thanks for the info Greg. I was looking at the picture thinking that's kinda like a B-train, that's what made me think of it. And there's talk that we are going to need two axle stingers to gross over 160,000 in NYC now. So curiousity got the better of me and I knew someone here would have the right answer. Thanks again.

Hey Todd, can you elaborate on this some more ?

Good topic I had never even thought about the doubles and triples endorsements for the lowboys.

Danny,
The NYC DOT is saying that in order to get a permit for 160,000 and higher you are going to have to be at least 100' long and have I think 9 axles. So that would mean a four axle tractor, three axle trailer with a tandem axle stinger. Axle config would most likely look like this:
Sounds like fun Todd, what axle configuration will you be running ? We took a Manitowoc over to Yankee Stadium in October on 8 axles. The crane weighed 150,000lbs alone. Straight over the GWB and then a straight-shot to the stadium. If you ever need any help don't be afraid to call...

Todd,
If you don't mind me asking, where in Staten Island did you move it?
Thanks,
Sal
Sal,
We are doing a parking garage on Central Ave. at the courthouse. We just started digging a couple a weeks ago. We are going to be starting drainage there this week.
Danny,
Right now we are running a standard six axle unit. 14,600 front, 50,000 rears and tri axle Trail King. NY gives us 130,000 like that. My father run a seven axle unit, 14,600 front 20,000 lift, 50,000 rears and a tri axle Trail King. NYS gives us 160,000 but I don't think the city is going to give us over 150,000 any more, but don't quote me on that. We haven't moved anything over 148,000 through the city in years. We're thinking about a new lowboy with either a fourth flip axle or a two axle stinger, but probably won't do anything until we start getting fines. Same with the tri axle KW, never even thought of a tri axle tractor until we got stopped a few times.

Screed, you shouldn't have to update the entire trailer. SO long as your trailer is in decent shape, and is equipped with a pin on, or able to accept a pin on, you should be able to purchase the T-bone and pin on axle for it. You don't need to go with a walking beam tail (California Legal). Self equalizing trailers are very heavy. You also want the ability to assemble a trailer that suites your needs. You can go with a heavy 2 axle lowboy, then buy the T-bone and three pin ons. This gives you the ability to run a straight 2, 3, 4, or even 5. Then you can step over to a 2+2, 3+1,or 3+2. You just need to learn how to shim it correctly, or you can go with a hydraulic booster. I can assure you, that this is lighter, and more versatile than a California Legal, also, why buy Cali legal, if your not running Cali? Personally, I would go with a Liddell before a Trailking. Liddell can build you a trailer that can even be expanded to a 3+3+3 in the future.

Greg,
thanks for the info. We have four lowboys. Three are in great shape and one has seen better days. Two are ten feet wide, we just use them for certain machines. My driver says the same thing about Liddell. I have been looking at the hydraulic boosters. Not sure what we're are going to do though. We definately don't need anything Cali legal. The farthest our trucks have been is Maine and Maryland. We need a trailer that is going to get us to around 180,000 occasionally. We are very rarely over 156,000. Once again thanks for the info.

The 85 ton arches Harris Camden took to western NY grossed out .4axel tractor 4 axel 53 ft Nuttall single drop and our 75 ton 6 axel stearables. We run up to 125 tons on the same combo. NY weighed every load and its their bridge !!
Great topic guys, very informative.
Hey John, I heard you gave J.B. a hand recently !
- Danny
Shimming an east coast spread is no big deal you get an idea after a few loads and usually get it right.
As far as I'm concerned you can't beat a Talbert for everyday use, and they'll build ant thing you want.

Grossing 228,000 on a 14 axle configuration is nothing special. By my guess, your tractor is about 25,000, trailer 18-20, and the dollie is about 25. So you are at a typical 68-70 light weight. So your beam was about 160,000. Normal for a dolly system. If you have the right axle, group, and bridge spacings, you should be able to go up to about 300,000. That is at 22 an axle, and 14 on the steer. If they let you go to 25 an axle on your drives and dolly, then 80 on your quad trailer, 14 on your steer, I could see you moving 125 ton, but you will have plenty of bridge restrictions. Back in my Robbins days, I moved 140 ton transformers around PA, MD, VA, and DE on a Cozad steerable 3/3/3 on a regular basis. Looking at a gross weight of 390,000 on 13 total axles.Screed, a hydraulic booster is the way to go, as you can get the weight off of those axles so you can back it up. With a normal shimable type, you are kinda screwed.

Greg,When you refer to "shimable " type, is this the conventional pin-on axle configuration ?
johndeere Posted: Tuesday, December 09, 10:38:06 AM Rank: Advanced MemberYea Danny that's what he's talking about. It's an east coast style pin on stinger, you normally pin it on at the bottom and put shims in at the top so it increases down pressure on the next set of axles. It takes some getting used to, you have to learn how many shims you need to achieve the right amount of weight on the rear axles. I pulled one a lot an I really never had any trouble backing up, I would just boost the front suspension all the way up then lock the stinger and deflate it. Then you can back pretty easy.

A liitle off topic since you are talking about trailers, but it was mentioned about the TBTA requirring a letter above 80,000#, how times have changed we used to go over everybridge in the city with 110,000 # GVW on a ten wheel DM 800 and the only thing we had to do was pay a toll and avoid the occasional scale.

Thanks for the info. How do you go about shimming this axle ? I guess I'm not all that use to this stuff. Our axle pins on with 4 pins ( two top and two bottom ) on the Rogers and Talbert. I definitely grasp the concept of how the down-pressure helps. Most flat tires wined up on the rear-rear, or broken trailing arms...
