Tankers and scales?

Of course you can set the tractor brakes only with a loaded tanker. The surge is only overpowering when driven by an idiot who dosen't know how to stop. As far as scaling goes, you can stay in the truck while it settles and set the brakes before you jump out. Setting the brakes immediatley throws the scale out quicker. Enough people do that and its recalibration time. You don't want to show up when the scale gets recalibrated. If you stop it like you know what you're doing it should surge lightly and settle quickly. With a CAT scale or any scale that weighs the axles seperate you set the trailer brakes and not the tractor brakes once it settles to keep the other platforms from binding and reading incorrectly.

We haul it because it pays good. Setting just tractor is fine, even if you do get a bit wild on the stop only the first smack or two is real violent. They settle down plenty quick enough to leave with just a tractor brake set. On another note I find that dumping the air in the tracter tends to settle them down quicker when scaling at a customer(Course this could also just be in my head too).

 

Not necessarily calling you an idiot. You are still learning the dynamics of tanker yankin'. Some folks never learn to stop these things smoothly. They are the idiots. You should not be overpowering the tractor brakes even if you only have spring brakes on one axle. Some tractors have spring brakes on both axles, some trailers have one axle equiped, and some have no spring brakes at all. Tankers can have a long service life and there are plenty of them still on the road with no spring brakes or wedge brakes. There are pressure tanks from the 1950's still running anhydrous and propane and you'd never know they were that old without looking at the original test date. The tanker I'm pulling now was built in 1984. Not many vans last that long.

 

I've often wondered about grossed out tankers and scales. I know when I have a lead wagon full of totes that is maxed out they keep me on the platform forever in Va because my drive axle keeps bouncing between 19,000 to 21,000 for a few minutes. Then I get pulled around to sign the ticket..lol..

Do they hold you guys there till the liquid settles for axle weights?
