Operating hours are recorded by the operating hour meter. The operating hour meter is
mounted in the switch box.
The owner of the mobile crane is responsible for recording and documenting the operating
hours.
Enter the actual operating hours in the inspection log for the annual inspection.
The actual operating hours "S" must be compared with the theoretic service life "D".
If the hour value of actual operating hours is greater than or equal to the theoretic operating
hours then a general overhaul of the winch must be executed.
A general overhaul of the load winch must be executed 10 years after commissioning at the
latest. For this the complete winch must be replaced.
NOTE!
Only the manufacturer can perform the overhaul of the winch!
Enter the executed general overhaul in the inspection book.
