Question:
Wednesday I made a drop in Tulsa at a new customer. I couldn't drop my airbags in my trailer to match the dock plate. We did compromise and made it work. The dock hand had no problem unloading me.
The salesman aka OWNERS SON , came out saying "oh no, send it back." I asked if they were serious. The dockhand said, "no, it's just the owners son and salesman." So we didn't pay much attention to him.
Today around 4 30 my FM called me up( on my vacation) asking me about the problem we had. I told her that my truck has no dump valve inside the cab and we rolled around like crazies under the trailer flipping switches and all. That did no good at all.
So she said before I leave out on the 26th, she will have me meet up with someone who can show me.
Question is, how do I dump the air in my trailer if I have no dump valve inside the cab?
P.S. The salesman emailed my company saying that in order for them to use us, we have to compromise. They weren't mad at me, I just didn't know whatelse to do. I double chocked my tires and all. Go figure I'm just as dumb as a box of rocks.Sweet Whiskey

Answer:
What type / make of trailer do you usually pull?
Answer:
Do a search on GOOGLE .COM for AIR DUMP SUSPENSION , most of the manufacturers have loads of info , GREAT DANE has a site strictly for info on the suspensions they use.

Answer:
That is the bad part. I pull all kinds of trailers. Great Dane, Utility, Trailmobile and all that goodstuff.Sweet Whiskey

Answer:
With few exceptions, all the the trailers I have ever pulled, the only way to dump the air from the trailer air bags was to set the trailer brakes, and then open up the release valve on the trailer air tanks. A few of the trailers I pulled would automatically dump the air when you set the trailer brakes.
All the trucks I have driven never had a trailer dump valve in the truck. The only air dump the trucks had were for the tractor suspension.
Answer:
Air bags in any trailer should deflate when the red trailer valve is pulled (on newer trailers)---older ones? You can dump the air (like Uturn said) by draining the tank under the trailer providing the valve is taken care of and can be turned without breaking it.
Sliding your tandems all the way forward will drop the back of the trailer some too.
p.s. Doesn't "comprimise" mean the two of you should work together to resolve the issue? If that is the case, why isn't the business willing to "get with the times", and have their docks raised to match todays trailers?It's apparent this place is never going to change....then again; why should it? It gets the clientel it deserves.

Answer:
I'm not sure what valve you guys are talking about. He did, however, turn the valve on the air regulator. Is that the one your talking about? The dock hand did that part, not me. I didn't have enough guts to tell him that it went to the tires.
That didn't drain the air, more like drained the tires. Then we got under the trailer and found some other switch thingy and turned it. To find out that didn't do the job either.
Who knows, I never really had to dump my trailer air bags before. Guess I'll learn something new again. That's the dang truth too. I can never get enough of learning.
Don't you agree Uturn? Sweet Whiskey

Answer:
Like I said: as well as Uturn.
Tank---the thing under your trailer right in front of the tandems that kinda looks like a tank.
Your air hoses are connected to the tank that holds an additional supply of air.
On the bottom of the tank or on either of the four sides near the bottom of the tank you will find a valve---usually in the shape of a wing nut (like the thumb end of a spam key or sardine key) for bleeding off condemsations (like on your regular tractor supply tanks).
Some times people will put a male coupler on the valve spout for hooking up an air hose etc..., but none the less it should have a bleeder valve on the tank under every trailer.
That would be the thing that looks very simalar to a tank.
p.s.--if someone asked me to drain the air out of my tires so I can line up with their dock---I would tell them to get (edited).It's apparent this place is never going to change....then again; why should it? It gets the clientel it deserves.

Answer:
or if it is easier to picture:
There is one sometimes two beer keg looking things under the trailer by the trailer axels.
On the bottom of these it is the drain valve. Kinda looks like a little "T".
Turn the "T" to the left and it opens the valve to release air and any water in that tank. Turn it back to the right to close the valve.
Answer:

Oooooooohhhhh! A tank! It's apparent this place is never going to change....then again; why should it? It gets the clientel it deserves.

Answer:
And here all this time I bet you thought you had to pull around a big chrome hot dog to get tanked in trucking.
Answer:
Hey Whiskey.....
On the dry van I pull the air bags deflate somewhat when you pull the red valve in the cab, although not much. Now on the great Dane Reefer I pull there is a separate valve in front of the rear tandems on the drivers side that I pull to exhaust the air on the trailer, then just push it back in when you are done.
Next time you are by one of your yards, ask one of the mechanics or another driver.
