Low boy ground clearance?

Are there any lowboys that can be raised to approximately 2 feet to not high center and or mess up a road or driveway?

My RGN detach (talbert) will raise the front probably 12-14" . It gets kind of tippy turning with it raised way up.. You can go to the rear and get 4-6" there by disconnecting the leveling valve and letting the bags go all the way up. With a 25' 6" well, that will get you off of most humps/ railroad tracks. If its steep enough that doesn't get you off of it, you shouldn't have been trying to drive over it with a lowboy anyways. Being able to lift the neck, is the big advantage of a non ground bearing style trailer. If you get hung up, all you have to do is fire up the pto or pony motor, raise the neck, and drive off it. If you have a ground bearing trailer, you have to try to get it lifted on the cylinder, stack shims in it to get off. Mechanical detach are even worse if you get hung up. Some perimeter trailers and schnable style trailers can really get some serious heights. They have big cylinders vertically front and rear, I've seen some that would get 3-4' of height on a load. Some custom trailer places build them, and I've seen homebuilt ones also.

I used to own a 50 ton Dynaweld NGB tri axle lowboy. It was a 2002 model year if I remember correctly. It had 5 ride height positions but you could raise it much higher than the top ride-lock position. I'm estimating that the front bottom of the bed was about 40" or higher above the ground at max height extension. I could walk under the neck at full extension with only a slight stoop and I'm a little over 73" tall. It was the best designed detach that I have ever been around. Third axle lift, easy to rehook even in uneven terrain or not 100% straight approach. I often wish that I had not sold it nor the Mack RD822s that pulled it. I don't miss taking care of so many tires.

The XL I pull now, and the Trail Kings I've pulled are fussy. Makes it hard for new guys to understand.

I don't understand why all newer lowboys aren't made to lift at least 2 foot or more off the ground for areas that it can high center on. Years ago I had to unhigh center one, it was a very ticklish operation, and there was no load on it. If I would have failed it would have been a mess, both the truck and trailer were junk in my book.

Airbags can make things more interesting. You ride up on something, things raise up and the leveling valve thinks it needs to lower, making you more stuck.

Some air suspension tractors have a switch on the dash that will allow you to over inflate the tractor air bags for additional clearance. A customer of mine has it on his 2021 W900.

I have not seen any hydraulic RGNs that you can't raise up well over 2' off the ground to get over something. Of course, you get above the locks, but if the cylinders can't hold the load long enough to get across an obstacle, you have bigger problems IMO.

I should go measure mine, I've had it clear up empty, spinning around in a bad curve with off camber pavement (a big hump to clear). We haul the big RT with a tall stop block, or we get hung up in our own driveway, where it meets the road. Its a off camber corner and will still drag a little. Smaller RT at only 44,000 you can get by with a smaller block.
