On-Board Scales?

i don't know anything about this calibration method. but i know where my gauges read. and that's what counts.

3 weeks ago i pulled into shipper at 9 a.m. they waited untill 3 p.m. to load me. 15 minutes later i was loaded and THEY ALL WENT HOME. an hour later i was tarped and went to the TS for dinner. my gauges were heavy. so i scaled. my 48,000 load weighed 50. so off we went driving a few extra miles AROUND.

my next load was 40 miles from the closest scale. my gauges read about 52. i told them take one off and then i left. had dinner and scaled. 100 lbs over so i had to watch my fuel.

 

I have a air ride truck and a spring ride hopper bottom. can your scales work on this. i would be interested if they do.

 

A quick google search turned up with these....

A little more complex than an air gauge, but you've got options...even with spring ride.

 

I am a fairly new driver and a tech geek and would probably look into something like this when I get my own truck. Your biggest resistance is going to be from the old heads who have been doing this forever and can eyeball a load every time. I personally couldn't be bothered with all those air guages and guesswork when I can get a device that does all that for me, I would consider it an investment. Biggest thing is the investment worth the cost. I could scale 70 loads for the cost of your device, so you basically have to pitch the cost/benefit of the device. Will it give a return in it's lifespan. What kind of guarantee does the company offer on the results. What happens if your device is off by 1,000lbs and the driver gets an overweight fine?

I was in sales for a long time. You think selling this stuff is rough, try selling headstones and grave plots. You get to tell a grieving widow the plot and headstone she wants will cost $4,000 and you learn just the kind of douchebag you can be to get the hard sell.

 

If you really want to get tech savy... build one that will digitaly read each axle on an onboard display. now that i would check deep into if you could come up with that one...it would read each axle and give you a total weight M/T or Loaded

 

And with liquid, we use high 5th wheels and spread axles. This keeps the liquid on the back spread.

Airguage works fine but is not needed most of the time. Chemicals are transfered by meter ( most of the time ) and the shipper knows the ppg....he better, he made the product.

That help ?

 

I've had Air weigh are now found them to be accurate at all times.

All equipment that I'm aware of the comes into Canada has suspension pressure guages. Tractors and trailers both.

My KW read 70 PSI and 17,000 kgs. (37400 lbs.) which is legal up here.

1 psi would equal 200 kgs. (440 lbs)
