I had an OSR in West Memphis tell me that when dropping a trailer to keep cranking till you hear air coming from suspension. That was at the one or three month follow up after going out. At annual, OSR in Atlanta said just lower landing gear till pads just touch the ground.
I'm driving one myself. Numerous drivers, "SNI," I know who recently received trucks are newer and are equipped with suspension height adjustment and load-transfer on the tag axle equipped tractors. The twin drive axel models don't require load-transfer but are equipped with adjustable air suspension from the cab. FACT! The company stopped ordering TAG Axle equipped tractors.
Yes sir, that is general rule of thumb so-to-speak. Hearing air release is indication that the support weight is on the landing gear, not the truck.
Are you on a dedicated account? I haven't seen one yet unless it was a tag axle on a dedicated heavy haul account. Last 20 new trucks I have seen, not one had it.
No sir OTR. The other drivers were either mostly OTR or regional. The new KWs I've seen were also equipped. One driver just received his 2016, with 60 miles on it equipped with, twin screw and adjustable suspension. I was also told by and OSR that tag axles were found to be to problematic for drivers, that SNI stopped ordering tag axles, that 'new trucks will be ordered with automated DT12 and twin drive axles.' I think we'll have to agree to disagree - not gonna argue about it. Purchase policy can change at anytime.
Can you post a picture of the dash and dump switch so I know what I am looking for? I haven't seen any communication about them.
My intermodal tractor has the dump/raise and weight transfer options. But it's really a necessity for us. Also, reporting whether a van trailer has defects does nothing- you have to call SEM and hopefully somebody will come out and fix it before the next driver picks it up.
Usually it puts a hold on the trailer so the trailer cannot leave an oc until the issues have been fixed. Which becomes an issue if you aren't told at the gate when you check in and try to leave the next day.
