    Having some issues at a location I pull out of with the landing gear on my trailers bending during loading. The trailers are brought into place with a yard truck, and dropped to be loaded. Aluminum Flatbed trailers. From what I can conclude, it looks like when weight is put on the trailers, the bow in the trailer begins to flatten out and since the legs of the landing gear aren't able to go anywhere, and the brakes are locked, it is bending the landing gear back. Happens on all of our trailers, and we're at a loss. I would assume there's supposed to be a support jack under the front of the trailer when they're loading to prevent this if it isn't coupled to a tractor? Air suspension dumps when Parking Brake is applied.

    You may need to have a yard dog back under that trailer so it can be lifted and set back down with the landing gear straight.

    It can be difficult or impossible to crank up landing gear that is bowed outward as you have described.

    I’ll bet their air ride and as their being loaded it will squat the back of the trailer because there’s not enough air in the tank to keep it fully elevated. bending your landing gear as the trailer is moving forward with the airbags are squatting!

    Dump your trailers before they start loading and that will fix your problem again that’s if it’s air ride!

    Our flatbed have been being equipped with the the type A pads. I dont ever use our flats so Im not sure if they’re a good solution or not.

    It is your air ride.
    Your air ride does not have enough air to support the load and therefore the bags collapse. Then the suspension pushes forward because the brakes are on.
    The simple solution is to dump the suspension air when you spot the trailer and tell the yard truck jockey to not inflate it during yard moves.
    If the air is dropped before the legs are lowered and brakes set then you will keep the strain off the legs. The arch coming out during loading will put some strain on the legs but it will be comparatively minor.
