Take your time getting on a scale!!

Its not so much about seting your brakes as it is about seting both your tractor and trailer brakes. Depending on the position of the tractor and trailer when you stoped and set the brakes. You could have pressure on the fithwheel going forward or back pressure. Plus angle on the two. Then when you set your brakes and the airbags level out it will can cause the distance from your drive axles to your trailer axles to increase or decrease.

This forces the pads on the scale further or closer togeater, basicaly raising or lower the pressure on the plates causing the weight to be lower or higher then it acualy is.

You have the same princeable when pulling onto a scale and holding the foot brake. This is why on allot of scales (specificaly DOT) you will see a sign that says release brakes before stoping.

You can acualy do an easy test of this on your own to feel the effects of the spreed. Drive around an uneven lot. then pull into a spot. when you are almost stoped start applying brake pressure to the trailer, while maintaining forward momentum, Then just before you come to a complete stop apply your tractor brakes and soon as you stop set your brakes. Now release the air in your tractor airbags. Ones it is lowered release your tractor brakes. and you will generaly feel the truck move forward a bit. If you where on a scale this pressure would have been directed at the ground while the brakes are set causing an inaccurate weight.

As for pulling on the wrong way. I dont think so. the sign says he went in the right way. No call box means nothing. Have you guys pulled onto every flying J scale? Many dont have call boxes, instead they work with lights or CB.

 

I'm using Firefox and see the pic in first post.

 

I guess I'm not supposed to see it. When I click on that, I get a new tab with a blank screen.

 

Every once in awhile we'd come out of the woods a little over on 1 end or the other. Before Electronics we had air scales and you could lift the bunk in front or rear by bring up your air pressure on the scales. Maybe 1000# or so. Just don't let those air scales pop off when you released them or the scale guy would hear them and well your toast.

hmm, let's try a different way.

 

You never scaled at an older J I am guessing, before they went to CAT many didn't have intercoms. Some had phones but the majority was a CB call.

 

this the scale lardo flying j

 

Already checked.

NOW I SEE IT!
