BUILDUP UNDER THE TRUCK SCALE

The next step in a truck scale inspection is to inspect all critical components. Depending on the scale, the technician checks for buildup of dirt, sand, mud and debris underneath the scale. Dirt buildup under the scale platform is often one of the top reasons for scale inaccuracy.

If the scale has bumper bolts, the technician will examine these and adjust if necessary. It’s also a good time to look at any other areas that may need to be addressed periodically such as junction boxes, grounding, rubber t-grip molding, load cell caps, pit cleanliness and more depending on the type of scale. The technician also checks cabling, structural steel, and concrete approach pads.

Next, the scale technician will drive the fully loaded test truck across the scale and check the sections for consistency and accuracy. Weights are recorded and used to assist with adjusting.

Next, the technician unloads all the certified test weights into a specialized weight cart. This cart is also certified by the state weights and measures department and is traceable to NIST. Then, the technician checks each section of the motor truck scale.

When we mention the word “section” we’re referring to an area of weighbridge which bears on two supporting platform points. Once the section testing of the motor truck scale has been completed, the scale can be adjusted and calibrated if needed.

The technician can once again drive across the sections with the fully loaded test truck which includes the certified weights and certified weight cart. The section weights and the overall weights should be consistent and accurate. The calibration and inspection is now complete.

The technician loads his vehicle and reopens the scale for traffic. Once the technician has moved off the scale and the scale has reopened, the technician completes all the necessary paperwork. The inspection detail report shows both the condition of the scale and components, as well as the as found and as left test results.
