Onboard Scales

I have a set of wireless on board scales

I have a hand held unit and can read each axle grouping.

Was a pain when I first got them to set up the mty. lded. wghts. but I like them very much..
Just word of warning, if using a wireless tire pressure system they work on the same frequency..
False readings on both then.

 

i have right weighs on both my trucks and all my trailers. really like them, inexpensive and they work.johnny

 

air gauges work great, and cost less than a couple hundred bucks for an entire set up.

 

my tractor has a PSI guage for the rears, it's a PITA, when it reads 60 I'm at 36,000 on my drives.

 

Those gauges are only accurate when on level ground .

 

Level ground with the brakes released on the axel group that you're reading. On mine the tandems are 34,000 even at 60 pounds on the tractor and the trailer, The only variable is the steer axel but if my 5th wheel is in the center of the tandems it's just not possible to overload the steers, They're usually at a max of 11,800 when it's in that position.

 

I have a set of the air-weigh scales on one of my trailers and my tractor, which
I like very much. They work really well and we plan on putting them on all
of our rigs.

 

The air scales are the same, all their doing is converting the same pressure a $10 gauge sees into lbs. You can buy actual load cells for a truck suspension, 5th wheel and front axle but they're very expensive.

The Air-Weigh instructions tell you to "Weigh on level ground with brakes released and engine running". There's nothing magical about these systems. You still have to calibrate the system with a set of truck scales, exactly like you would with a cheap gauge. The air systems will make your wallet lighter, no calibration needed.
