Pitless scale Pitless scalePart of the mechanism of wagon scales was normally in a pit so that the scale platform was at ground level and a wagon could easily be pulled onto it. However, some scales were built so that the entire mechanism was only a few inches thick and, by using a small incline, a loaded wagon could still be pulled onto the scale even when the scale was totally on top of the ground and the wagon was heavily loaded.
