Airbag dump with brakes question

Hey guys,
My company leased several trailers that sit taller than I’d like. The bags are sky high and they don’t dump when you pop the brake, nor do they have a separate drop valve. Is it simple to set them up to drop the bags when you pull the red knob out? I mean, this is the standard setup so surely it should be doable. I’m just trying to learn more before I lean on my boss again to call the lease company.
Thank you

 

Correct, blue ogre.

 

Hey thanks for the help, blue ogre. I work at a food production plant and split time between hostling with the goat and running around town in a KW tractor. We are always dropping trailers in the doors and unhooking to do other moves. Yes the trailers do settle forward a bit; I think the airbags being so tall only makes that worse. Yes most of them do have the rear support bars or whatever they’re called at the rear. I do think they could be an inch or so lower before hitting them though. Andy just coming down an 1-1.5” would really help though, as most of our docks have a 3.5-4 degree pitch and this seems to exaggerate the effect of lowering the trailer’s rear. Our docks are mostly using those cheap style plates that the loader uses the pole to flip up and out onto the trailer. They are not the larger and longer better sprung systems that are less picky about trailer height. We had no problems with the McKinney trailers , but we went with Penske this last year and man, that little extra height is a royal pain.
Thanks again!

 

And if could just pop the brakes and dump the bags when I drop the trailer, I think our problems would be solved.

 

I’ve done what you said about pushing back on the trailer after it settles a bit, I usually am in a hurry though so i only do that on one particular trailer that’s a real rambler.
Yeah we’ve taken to jacking the landing gear sky high to get the rear down but that sets up other problems. Our genius boss thinks that everything can be fixed by sliding the tandems way the F forward ( it Does lower the rear, he’s right about that) but that creates many, many other issues that he doesn’t care to understand and which I’ve repeatedly told him. The problem is my boss, mainly. We’ve all been there, lol. He doesn’t have the sack to call the lease company and talk about dumping the bags or a leveling valve adjustment, and I don’t know enough about it to lean on him harder. That’s why I’m trying to learn a bit more.
Thanks again!

 

Thank you, kwswan, I’ll check that out.
