8 Inspection and servicing intervals
The inspection and servicing interval for a drive is 12 calendar months for a crane in an 8-hour per day,
5-day per week work period, under normal environmental conditions (free from excessive dust, moisture,
and corrosive fumes). The inspection and servicing intervals of the drive could be defined by Safe
Working Periods (SWPs) if it is being monitored. If the Safe Working Periods is being monitored, then
the servicing interval must be carried out at the end of the Safe Working Period (SWP%) of the crane or
hoist, or by the end of the stated number of calendar months, whichever comes first. If the drive is being
used intermittently, it should be inspected before being used again.
F
If the duty is heavier, or the environment severe, service intervals should be shortened and more
frequent.
Only authorized or adequately-trained personnel may carry out service or repair work. If any defects or
abnormalities are observed, they must be investigated and corrective action must be taken in accordance
with the instructions.
