Braking work until maintenance

To determine the permitted total number of emergency-stop braking operations, the following values for the braking work until inspection (WInsp) are used as the basis for calculation.

In addition to this approach, the total number NB2max of possible emergency-stop braking operations is limited to the following values depending on the load range and the degree of gear unit utilization, regardless of the calculated numerical value from formula no. 1.9:
