Lift Axles and Lift Axle Controls

Done it several times without issue. 40,000lb rears will handle 50K without much issue and can handle 60,000 if you're driving it right.

So, here's the simplest answer I can give.you want to be able to run Canada, where a lift won't be recognized. Also, regulations about lift axles vary state to state.

Your truck can be fitted with a lift, but, due to the frame, anything heavier than maybe a 14,600 lift is going to be a bit much for that truck. Remember, when you add a lift, you're effectively adding a stress point on the frame. Adding a lift can occasionally necessitate adding a cross member.

KISS. Keep it simple stupid. What you have right now will handle 120,000 gross without issue if you drive it right. You'll lug down with the higher rears, but they will work, along with the 10-speed. What you have will do fine. Don't ovethink it. Be smart about where you park so you're not doing loads of inclined starts, keep your foot out of it, the small Volvo grille will not allow the airflow of a square nose or T800 widehood.

Dump the truck at the end of its service life and then think about something a little heavier spec. Don't go crazy. Most guys want 48K rears, 20K steer and lift, double frame, big power and 18-speeds to tow a three axle lowboy. That's overkill. 14600 steer and 46K rears would be plenty enough for a 3-axle.

Besides, super heavy steer axles are asinine on most lowboys, the neck is too short to get that much weight onto the steer.

16400 steer is the absolute heaviest I would go pulling a three axle, and I best have a cheater kingpin with an 18-inch or shorter depth to utilize that.

Doing over the road, you'll never peg the sort of weights local guys do to need a super heavy lift either, reason some of the OTR guys have them is for delivering or loading when you have to get into a mine with a 2-2-2 or 2-3-2 and have to longneck it with 90,000 on the drive and lift.

Even so, you could do without, just be careful and smart. the amount of weight necessary to snap an axle would be astronomical, snapping axles happens when you lose traction quickly and then regain traction, it's the rotational force that snaps the axle. If you ever see one, look at the core, you'll see, a.) The inside of the axle is softer steel. This is intentional, to allow a little bit of twist so the axle doesn't simply snap when you put power to it, and b.) If the axle has snapped you'll see striations twisting in the direction the axle was travelling when it snapped.

 

Funny thing bout you posting a screen plant.
Fri. was the first time I have ever hauled one in doing heavy haul since 1990.
It was a learning curve. 2 hours too ld. in at the plant.
Oh guess who gets to unld it at the port???
This will be fun

 

wait until you get one with a lot of hours. loose tracks jumpy remote controls (when they work correctly) and delayed signal!

 

Well even new ones do that. The portable crusher that I lded years ago, that they bypassed the safety controls was like that. Brand new.. Of course it ended up getting rebuilt after my miscue...

 

What engine makes 1850 torque at 485 horse?

 

Not my 60 series Detroit...

 

Cat had a 475 1850, in an Acert.

 

Didn't realize that.
