6X2 Lift axle on New Volvo

I lift drops when it's slick.

 

34,000 on a 20,000 lb axle seems excessive...

 

Some drops have a adjustable down pressure control.

 

I run a 3 axle lift 6x2 don't fully understand the questions mine has a control inside of the cab

 

Nussbaum (sp) runs that set up they are out of Illinois . They have freightliners. Told me their dead axle doesn't lift but you can drop the air in the suspension some. Also talked like the drive rear has some sort of lock if in a tight spot where you need some extra traction. Called them a few months ago about their used trucks. Some LTL company used them. Mayby USF Holland?

 

What do you mean locked out? There’s no differential and no power to that axle.

 

think he's talking about the locker they usually put in the drive axles on 6x2s to help with traction. No idea why he would be worried about that not working though.

 

I have a steerable lift axle on my ProStar, 8,000 pound unit, West Coast truck that hauled propane, the application I bought the truck for. It goes up and down with a switch on the dash, it steers by itself, there is a valve in the side box to adjust the ground pressure. It stays down until I hit the switch to raise, put it in reverse or set the parking brake. No clue what you are asking in regards to slippery parking lots. Why do you think you need a lift axle?

 

The freigFreight I'm drive 6x2, supper singles. It will automatically let air out of tag axle if the drive tires spin. It supposed to have locking drive axle but Freightliner or the axle maker set it up as electronic locking. So it not a true locker. It just ABS in reverse. So iwhen a wheel spins it applies the brake to that wheel.

The truck is bad in the snow. It will spin tires in the rain when empty from a stop light. It also spins the tires when sliding trailer tandems on dry pavement.

The truck will inflate the drive axle air bags to put more weight on the drive axle. That how we slide the trailer tires. I'm not impressed with the setup. My company is going back to 2 drives axle with power, on all new truck.

 

I drove a Mack stringing truck like that Brandt. It sucked off road.
