What to Expect

Robert Pepper, an independent automotive journalist says this is what you should expect from a Mobile Weighing Business

  1. Scales calibrated every year or as required by manufacturer, whichever is less, with certificate on website;
  2. Uses at least 4 scales;
  3. Explains GVM, GCM etc accurately, doesn’t just provide you the numbers;
  4. Checks limits carefully eg sometimes a car’s max tow is limited by the towbar or hitch fitted, and there is often variation in max tow depending on transmission and engine;
  5. Can provide references;
  6. Takes care to weigh on a hard, level surface as even a slight slope or soft ground throws the numbers out;
  7. Has contacts with engineers for modifications as required;
  8. Understands that weight important for legality, but for stability weight distribution is more important;
  9. Does not insist on 10% TBM (there is no perfect TBM, it’s very situation-specific so without drive tests you cannot say what it should be);
  10. Provides a written report with measurements and explanation. Report includes at minimum:
  • Measurements of weight on each axle (note: some carmarkers do not provide axle loads because they simply do not appear to understand the importance)
  • Margin to limit (axle loads, ATM, GTM, TBM, GVM, GCM)
  • Effect on rear axle load of TBM (which isn’t simple – watch this)

You should be prepared for bad news.

What not to expect

  1. Towing training
  2. Complete explanation of towing, dynamics and weights; there simply won’t be time.
  3. That’s what you can get from looking at my work ahead of time! Then you’re in a position to have an informed conversation in even more detail with your expert, as opposed to them spending time on the basics.
