I draw your attention to the fact that the name of art is composed as follows: the first letter, for example R - type of technique, R - excavator, then the number - Capacity, the last letter - wheeled Here the most important, such as R130W-3 is 1.3 tons, but there are other Writing - 1300W-3, and it's the same thing, I checked on the example of several excavators.
