STRATEGY FOR CRANE MAINTENANCE
Handbook section 18.104.22.168
Confirm that the duty holder has appointed a technical authority responsible
for maintenance of lifting equipment. Interview the technical authority
responsible for crane maintenance and probe to establish the rationale behind
the crane maintenance strategy. Discuss how the maintenance strategy takes
account of: the crane duty, crane usage, operational experience, maintenance
history, and the consequence of failure. Explore the extent to which the crane
manufacturer and or a competent authority been consulted.
Supplementary lines of enquiry that may be followed at your discretion to explore the above issues.
Inspect a copy of the maintenance strategy document(s).
Discuss the outcomes of any associated Failure Modes and Effects Analysis (FMEA) and or Failure
Mode, Effects and Criticality Analysis (FMECA) studies. How have these influenced the maintenance
Explore how crane maintenance tasks have been prioritised. Inspect sample work orders for a typical
safety critical component such as a hoist or slew bearing
