    My thoughts exactly.

    From the photo the tractor and jeep are together and intact.

    Was there a structural failure on the trailer?

    Some on the comments section thought he was going too fast, the most prevalent was he was going to slow.

    Here is one comment posted by a dad, perhaps this is the reason.
    On what appears to be the inside of the turn, judging from the picture? Centrifugal force is an outward force from the center, which means the turbine should've rolled to the left. It appears it might have been due to the centripetal force (the opposite to centrifugal,) causing it to roll to the right, or the inside of the turn.
    Oh how I enjoyed watching Mr. Wizard with the kids.

    What a bad moment for the driver. Good thing no one was hurt.

    He didn't take the turn wide enough. The inside trailer tires dropped off the shoulder, he panicked and overcompensated. Jerked the wheel to the left, which caused the weight to shift to the right. The sudden weight shift combined with the steep bank of the road was apparently enough to make it tip.

    Well look at it. An accident waiting to happen. It's tall, it's too wide for the trailer, and it weighs 70 tons. Who makes these logistic decisions? So close, and yet so far.:biggrin_25513:
     
    Interplanet Janet Thanks this.

    It's steep (banked) enough. A lot of weight, relatively high COG, the inside air bags can be slow to respond to massive weight shifts and in such a turn with shifting weight, and the outside bags already heavily inflated, can effectively "push up" in response to the changing dynamics, exacerbating the problem.

    Add in the fact that the load is also going uphill and a lot of weight get's transferred to the lower bags and suspension components at the rear of the trailer. May have simply been a poorly engineered trailer design was the chief culprit.

    Also maybe a weakened or defective 5th wheel king pin or 5th wheel pivot pin snapped.

    unless the trailer managed to slide 10 feet after it rolled.

    looks like the trailer was off the road. he turned too sharp instead of clogging the left side of the road. to keep the trailer on the road instead of dragging it into the dirt.
