6.3.2 Frequency and deadlines for maintenance interventions
The frequency of the following operations refers to a jib crane used in normal operating conditions and are
valid up to service group M5 (standard ISO 4301/86) or 2m (FEM 9,511 rule). If the use of the jib crane is
normal and correct for a daily 8 hour shift, the following overhaul may be performed after a use period of
approximately 10 years (FEM 9,755 - S.W.P. rule) If use is over various shifts, the maintenance periods
need to be reduced proportionately.
