no, i'm still going with the brand new wilson roadbrute. we did modify the specs a little bit. now it's going to have a REAR AXLE SLIDER, with the spread of 10'1" in the open position and 72" in the closed position. 72" spacing is the maximum allowed in Western Canada. So, I'm legal in the money-laden Alberta and BC Because the rear axle's center sits at 31" from the rear of the trailer and the king pin location is 24" (the upper deck is 10' long) the pleasant surprise of this modification is that now this 48' trailer is california legal! in the closed position, the rear axle is just under 40" from the king pin. the deck height with 17.5 tires is still rated at 34" when loaded. because of the rear axle slider the dealer said they have to add a reinforced bumper called "Rear Impact Guard". That added $300 to the price and a little weight... It's now at 10,300 lbs and US$35,769 F.O.B. Breslau, ON, Canada (or $1,500 cheaper if I pick it up myself in U.S.).

 

I do not think the California rule applies to 48 foot trailers. Here is a link:

Truck Route Classifications

I will add a couple more things:

1) If you have a 10 or 11 foot upper, and a REAR slide, you may have problems axling out 30-35 foot loads that go on the bottom deck. The trailer axles will have too much weight. That was part of the reason for going with an 8 foot upper. Many Americans don't have to deal with this, that's why you don't hear about it. Of course a spread may fix the problem. But it won't in western Canada because your axles will be so far up.

2) With the big push for 6 axle 97,000 lb setups in the states, I would really push for a triaxle setup with a lift rear axle. Imagine buying a new trailer and a few months later it's made obsolete.

I just loaded yesterday, and would've been able to take 5 bundles on a flat. But because of my step interfering with the load(29 foot bundles) there was too much weight on the rear trailer axles. It was around 37,000 lbs. With an 8 foot upper and a rear slide, it still wouldn't have worked. BUT with an 8 foot upper and a front slide it probably would've.

Remember that with a spread, you cannot scale more then 20,000 lbs on the front axle. That usually means you can do about 38,000 lbs on a spread.

Also I've talked to many guys at my company with 72" spreads(that's what I have) and they wish they went with a super tight spread instead of 72". Easier to scale.

 

Cali does not have the 40ft bridge law on 48' trailers.In ca only trailers that are longer than 48' have to comply with the bridge law.I live out here in ca and have a 48' 102" spread axle 10' 1" wilson road brute and have never been messed with.
I do like my wilson by the way, they make a great trailer and are nice to work with.The people in Souix City,Ia will do what ever they can to help you out.Also they do seem to sit lower than the other trailer mfg's steps with 255/70-22.5's.I can haul 10'8" on in the western states legally and 10'4" thoughout the rest of the country without getting into permits.
I have had people with the lo pro steps try to tell me when I show up to load with them "oh you can't load these with a std. step you will be over height" I tell them not a prob. after I get loaded we will get out the tape and see.When the see the overall height they are confused that it comes out legal.
My lower deck is 40" with no load put a load on it and it flatten's out to about 37"-38" depending on the load.

 

OK need more info on this? What push?

Where is this rule? In the US at least, I thought they treated a 121" spread like a group and let you have 40,000? i don't think I've ever had anyone scale my trailer axles seperately.

is this a western canada thing?

 

It's all over the news? Almost every trucking website has had quite a few articles on it. There's a bunch of trade groups lobbying Washington to push it through. ATA is a major backer. 6 axle setups weighing 97,000 lbs.

The group can have 40,000, but each individual axle cannot be more then 20,000. Since the front axle always takes more weight, that means we cannot have 40,000 and meet the other rule.

Anything over 72" can only have 9,100 kgs(20,000 lbs) in western Canada. Hence the reason for single axle sliders.

 

Jeez! You'd think trailer salespeople would know such things! Thanks, Alan. I'm sending an email to my trailer "pro" to see if we have to change the specs again.


So, what would be a good solution for this. Since now I don't have to worry about California, maybe I should just make it a FIXED SPREAD of 72 inches, like yours? This would be legal in Ontario and Western Canada and save me some money and weight.

I saw DeckX stepdecks all have their axles tight together and at the very back of the trailer. Maybe this is the best way. I'm not sure now what to do Why does MacKinnon say "a front axle slider is essential"? This is just BS.

 

For the time being I"ll just hide the chains and binders in the truck's side compartments.

 

Check out the attached PDF with Alberta weight rules. The thing with Western Canada is they allow the spread to be anywhere between 1.2 m (47.2") and 1.85 m (72.8"). As far as I understand the spacing doesn't affect the weight limit at all. If it's a tandem axle with dual tires you can load 17,000 kg or 37,400 lbs. I don't know why my spec shows 72" spacing in the closed position with a rear axle slider. And why do I need to bother with these sliders at all. Allan is right ... with my 38 ft at the bottom there'll be too much pressure on the rear axles UNLESS they are in the very rear.

DeckX uses steps and flats. They run Western Canada and Ontario. See how their trailers are spec'ed here transX - Equipment They all have closed FIXED tandems in the rear!

note: couldn't attach the pdf files; they were too big.

 

You won't over load the spread with an 11ft or 10 ft upper deck.You just have to know how to load the trailer.That is a myth i have loaded 45,000lb on my trailer before with 2 pallets of roofing material on the top deck and the rest on the bottom and was still under 40,000 on the spread.I run with the 5th wheel slid up as close to the truck as I can without catching my mudflap hangers on a truck with 260" wheelbase and load the front of the trailer heavy usually and work my way back.If I had to do it agian I would by a closed tandem though.If you know how to load a trailer a closed tandem is not a problem plus it save on tire wear and you will get a mpg increase due to less tire scruffing while going down the road.
I leased to a company once that had both spread axle roll off trailers and closed tandem trailers and me and the other o/o noticed a .5mpg increase pulling the closed tandem with the same loads and weights.
Just my .02

 

What size closed tandem? Just the same as they use on the truck's drive axles?
