I finally remembered to ask this question about trucks or trailers that lift their axles

    When I pulled food grade out of a Northwest, our Volvo's were set up to have automatic lift axles. You can control them manually with a button in the cab, but they would automatically go down when you were loaded. If you're driving a single screw tractor, it's useful because you can increase downward pressure on your drive axle for when the road is slippery. Makes it easy getting under a trailer on a dirt lot too. You get almost 3 miles a gallon better lifting one or two axles when you're empty, so that was the primary motivation for it though

    As for easier turning? I didn't notice a difference

    The cops love to watch loaded tri-axle dump trucks trying to pull this one. Then they can sock them with a huge overweight ticket.

    Running empty it sure saves a bunch with a spread axle trailer though.

    That's the way that always seems to go isn't it.

    You'll be screwed if that sensor fails and lifts when heavy

    All depends on how it was plumbed. If it was plumbed right they would wire it so it takes power to lift it. So that way if the sensor fails or it losses power it drops. Or at least that how I would wire an auto drop/lift axle.
     
    TruckRunner Thanks this.

    I just started a 6x 2 thread as i'm close to buying a new tractor. On those tractors with lift axle, when down can you lockout the axle?
