6.3.2 Frequency and deadlines for maintenance work
The periodicity of the following operations is for jib cranes used in normal working conditions and is valid up to the
M5 group (ISO norm 4301/86) or 2 m (FEM rule 9.511).
If the jib crane is used normally and correctly for a daily 8 hour shift, overhaul can take place after a period of about
10 years (FEM rule 9.755 – S.W.P.). If used during a number of shifts then the maintenance periods must be reduced
proportionately.
