What our service work and the manufacturer documentation say about keeping this model running.
Weekly engine test run (min. 5 min). Release hook servicing annually by an approved service provider (SOLAS MSC.402(96)). GRP hull inspection at docking. Five-year thorough examination.
| On-load release hook thorough examination | annual per SOLAS, with 5-yearly operational test under load |
|---|---|
| Wire falls | renew per manufacturer/class schedule, typically around every 5 years or earlier on condition |
| Diesel power pack service | per engine manufacturer's interval, typically every 250-500 running hours or annually |
| Hydraulic oil | change every 1-2 years or per condition monitoring |
| Winch brake inspection | annual |
| Davit structural inspection | 5-yearly at major LSA survey, or on damage |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Wire fall diameter reduction | renew when diameter reduction exceeds roughly 10% of nominal, or per class/manufacturer criteria, whichever is stricter |
|---|---|
| Brake lining thickness | renew per manufacturer minimum, generally once worn below about half of new thickness - confirm against Hatecke manual |
| Hook trigger clearance | set only to manufacturer's tolerance and documented procedure - do not field-adjust without the Hatecke manual |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
LSA equipment is a recurring survey item: annual thorough examination of davit, winch, and on-load release gear; no-load operational test at each annual survey; 5-yearly dynamic/load test of falls and davit under working load per SOLAS Ch.III and the LSA Code. Hook overhaul and re-certification records (matching model number 3351306 Lux) should be onboard and cross-checked against the maker's service history.
Estimated lifetime: LSA davit/winch structures are generally expected to remain in service for the vessel's operating life (commonly 20-25 years) given scheduled overhauls; wire falls and release-gear components are life-limited and renewed well before that on a calendar/condition basis rather than running hours.
