Why is the approval of the Trade Approved front end loader scale conditional?
A front end loader scale is unique in that the manufacturer of the scale does not manufacture all the components of the scale. The scale’s accuracy may be influenced by the mechanical condition of the hydraulic system of the front end loader to which it is installed. This is why the manufacturer of the COMPULOAD series of scales elected to submit its scales to the NSC for testing, already installed on a second hand front end loader that had some 3,600 operational hours. Compuload was the only instrumented submitted to the NSC on an actual operational front end loader. All other instruments submitted for testing, were installed on newly made hydraulic jigs to simulate the loading actions of a front end loader.
