I believe this is a dumb question, but no manuals/operator guides tell me the answer.
Have an early 90s Eager Beaver 50T NGB RGN lowboy (3 axle). There is one "flip up plate" that is used for the gooseneck pivot to rest against, presuming for normal road travel. That plate flips down and then the neck can fully pivot down to set the trailer on the ground. There are no other ride-height adjustments with a cam or other like I've seen on some other units. This is all spring trailer, same for truck, no airbags.
Can you run the front of the trailer up on just the hydraulics and haul that way, such that the cylinders are taking much of the stress? I presume the answer is no. Can you make up your own plate/block to put in that spot to make the trailer run a little higher?
This new-to-me old trailer has diamond tread plate put over the wheels. When moving my 20T excavator with it for the first time, I had the left front trailer tires rub on that diamond plate to the point that it locked the tire up on flat pavement. I ran the neck up some to put more weight to the back of the trailer and that solved the immediate issue.
Have not looked further to see if there is a failure causing this, nor if the wheel covering is just been knocked down too far from previous loads. No issue when running unloaded and nothing obvious to indicate something is broken or bent.
Obviously I'm concerned that the tire could be rubbing at other times when such a small change (raised neck by 1") appeared to be all that was needed.
