What do you mean by "380/275" in the vibratory force (kN) of vibratory roller?
It means "to".The range of exciting force is between 380 and 275.
In the question, 275 did not give the amount of engineering units, I just guess the following is KN.
Or what it means.There are two modes of operation for a vibratory roller. The first mode produces the exciting force of 380KN while the other model produces the exciting force of 275KN.
