| Wire rope inspection | every 3 months or per class requirement |
|---|---|

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Wire rope discard criteria | per ISO 4309 or the maker's criteria - typically discard around 6 broken wires in one lay or roughly one-third rope diameter reduction; confirm against class rules before acting |
|---|---|
| Slew bearing axial/radial play | check against the maker's tolerance table - excessive play is usually flagged well before it becomes visible |
| Boom pin/bushing radial clearance | heavy-lift crane pins typically allow only a small fraction of a millimetre of play before replacement is due - confirm the actual limit in MacGregor's maintenance manual |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Deck cranes are typically Continuous Survey Machinery items: annual thorough examination, function test of overload protection, and a proof load test at an interval set by class rules (commonly every 4-5 years). Wire rope inspection records, NDT of highly stressed structural members, and load test certificates must be retained onboard for audit.
