  • Page 70 Maintenance overview 5.4 Measures required for winch monitoring The actual service life of a winch is affected by a number of additional exter- nal factors, such as: 1. Overloading caused by improper use of the truck crane. 2. Insufficient maintenance: Oil is not changed at the specified intervals.
  • Page 71 Maintenance overview 5.4 Measures required for winch monitoring Determining the The truck crane's load spectrum is divided into groups (see also ISO 4301/1, operating FEM 1.001): conditions (load spectrum) When determining the load spectrum, the existing rope pull is used as the standard, i.e.
  • Page 72 Maintenance overview 5.4 Measures required for winch monitoring One of the load spectrums listed above should be selected on the basis of the actual operating conditions and entered in the crane logbook for the respective testing interval. Note for truck cranes: The load spectrum L1 and the factor of the load spectrum Km = 0.125 are generally applied to truck cranes in assembly mode.
  • Page 73 Maintenance overview 5.4 Measures required for winch monitoring The general overhaul is to be arranged by the operator and performed by the manufacturer or a representative authorised by the manufacturer. The results are to be entered in the crane logbook. The manufacturer or an authorised representative will specify a new theo- retical service life D upon completion of the general overhaul.
