Heavy Haul Miscellaneous Thoughts, Ideas and Questions

I have to agree with Ron on this. If you're spec'ing and building new, pin jointing the back end is the only way to go. It give you so many options;
-the ability to shim the back end to run slightly positive no matter the load weight, or especially when running empty
-the option to also change from deck to rail/beam. Lighter tare weight, lower loaded height on equipment, etc.
-you can add section to increase well length for the oddball loads. This involves a little more work than an extendable section, but you don't have that extra tare when it's not being used, which is most of the time! IMHO, section over extendable is lower maintenance, and longer life of the working deck. Extendable's sag, sections & pin joints are shim-able.

If you want an awesome trailer spec to copy, or order from let me know. I've got a buddy that has an incredible 7/8 axle trailer. If I was to go back to 7/8, no question, I'd order a carbon copy of his.

 

What brand is it?

 

It's a K-Line.
Built in BC Canada.

 

Thanks to everyone that responded. Lots of great information. I will work on digesting then get back to you with more questions.

 

not recommended but can be done. etnyre and globe have a hydraulic flip they sell. I have flipped mine when there was no other option around.

 

Flipping down pretty easy, like when at Wy POE and they consider your flip as a lift axle and say "all axles deployed over 80k" . Chain, tow hook and $89 later problem solved.
Flipping UP, block of wood, come-a-long and some elbow grease.

 

Ground bearing trlr's pretty old system.
Consider, on mechanical trailers, how you have to drop your trailer to take weight off neck to release pin and pull dog bones?
Ground bearing trailers use hyd cylinder that drops straight down to raise trailer to accomplish this, and allow's slight shimming for adjust height.
Hydraulic necks accomplish this much easier with better adjustability height wise.
It's been MANY years since I've messed with one. I just remember them being a pain on uneven ground at job sites.
Someone can correct me if wrong but that's all I can recall.
Don't know why you still hear the term so much, maybe there's still some geezers older than me still like'em.

 

Yeah that's pretty much it in a nutshell. A ground bearing uses a cylinder pushing down to raise the trailer. Non ground bearing uses cylinders in the neck pushing against itself to raise the load (that's what you're used to). There are still blocks of wood buried from those trailers pushing them in the ground. Sometimes you couldn't carry enough wood, and you didn't dare try to pick a heavy load on asphalt.
