Tri Axle Trailers

[bdog]

I have a triple axle belshe backhoe trailer. It has three 7k axles, 21k GVWR and Pintle hitch. No issues with it so far but haven't pulled it a lot. I would have preferred a tandem dual but I got a good deal on it.

I don't think you need a triaxle is what I'm saying. If you can carry the correct tongue weight a 14k trailer should be enough although it would be right at the edge. If you can get by with 8k axles, why would you want another axle unless the price was worth it?

I'm not a weight **** and opposed to being overweight on occasion, but I'm also not banking on 25% tongue weight. 14 -4 for trailer weight equals 10 then maybe 10-15 percent tongue weight plus extra buckets, fuel tank, tree saw brush cutter etc. Of course I can get by with 8k axles, but the dilemma is 8k axles for $9,000 plus or tri 7's for $7,000. I want a tilt in the 20' range for quick loading and getting into farm drives that are tight for the long goosenecks. The other dilemma is 78" track widths on my machines.

Load Trail and PJ both make tilt bed gooseneck tandem axle single tire trailers with GVWR of 15,680. 7k axles with super heavy duty tires. I think they run 7 K. 80+ inches between the fenders.

Anyone have any PERSONAL experience with them? Not looking to hear what you've heard from so and so.

Here's the deal, I need to haul a mini excavator that weighs 12k. With a 14k trailer weighing 4k I'm only at 10k gw.

I have heavier goosenecks, but I want a 16+6 tilt so it's shorter and easier to haul to certain spots than a 32' gooseneck. No one really makes a trailer like that with 8k axles aka 16k gvw. Most want to jump to 3 7k axles. I noticed PJ used to offer the 8k, but not longer do and only offer the 3 7's now.

I'm hesitant about a tri axle bc of rumors of tire scrub and wear, but I've never talked to someone that actually has one, it's all just rumors.

Here is a company that makes a 17,000gvwr 16' pintle trailer with 8k axles.

I also don't think you are quite looking at the math right. Many manufacturers play games with their trailer ratings. If you have dual 7k axles and a 14k trailer, you have to calculate the tongue weight as a percentage of the 14k, and then ADD it on. If you look at that moritz, they are already assuming atleast 1k on the tongue if you go with the 8k axles because they state it's a 17,000 GVWR trailer.

I have a GN with 3- 7k dexter axles. I bought cheap. when I first got it I was eating up the back tires on it and found the rear slip hangers were worn and it caused the axle to run crooked. I fixed it and have had no issues since. I make extremely wide turns.

It is what the trailer is tagged at. If it's tagged at 14k then you subtract the weight of the trailer which is 4k so you can "legally" haul 10k is my understanding. Yes the 8k axles are tagged at 17k, but they are tagged at that. The 7k axles are tagged at 14k. Unless I'm missing something?

I recently got a triaxle trailer. The tandom duals either lost the required 82" width (like stated you needed) or required a deck over which raised the bed such that it made other problems that I could not accept. I did not want the tri axle for all the reasons that people have about tire scrubbing but it was the only option I could identify that fit my requirement.

I don't yet have a lot of time on it as it is still new but as I was turning and backing in places that I expected to have issues I saw no significant tire scrub compared to what I expected. I can tell you it pulls like it is not there.
The GN (great northern)vs PJ is obviously a money and distance issue. The warrantee on the two is not comparable nor is the quality but you do pay great northern a premium price for a premium trailer. One of those reasons however is the things that are standard on GN that other manufacturers add on as options. Once the options are added the same configuration that is standard on GN the price is much closer. Of course if you did not want or need those then why pay for them. Different business models. PJ has a great dealer network and has more options to modify a trailer than you can imagine. If you want it they can build it in that specification. Me I would buy a GN any day over the PJ. There is no comparison on longevity of the frame and overall build quality.

Dump truck trailers around here have 3 or 4 axles, and some are spring centering steering axles.

Too expensive for smaller trailers? No one makes them in smaller sizes?

This seems promising. Says he can do 82" with the 8k axles.

Ok let's look at it this way. If you take 14k-4k to get a 10k payload, are the 7k axles actually carrying 7k? I say no, Unless you have 0lbs tongue weight which we all know is not a good situation to be in.
