Recurring inspections of equipment, cranes and suppor-
ting structures by an expert once a year. In severe condi-
tions, e.g. frequent operation with full load, dusty or ag-
gressive environment, high switching frequency, high
switch-on duration, the test distances must be shorte-
ned.
- Experts for the inspection of cranes are, in addition
to the experts of the TÜV, only the experts authori-

the test book.
