What our service work and the manufacturer documentation say about keeping this model running.
Hydraulic system maintenance critical. Oil analysis annually.
| Hydraulic oil change | typically every 2,000-4,000 running hours or annually, per the maker's schedule |
|---|---|
| Gearbox oil change | annually, or per running hours per the maker's manual |
| Brake lining inspection | every 6-12 months, condition-based |
| Wire rope inspection | every 3-6 months per the rope maker's/class guidance |
| Brake holding capacity/render test | per class/flag requirement for mooring winches |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Brake lining thickness | renew at the maker's minimum-thickness mark, commonly around 50% of new thickness - confirm against Rapp Hydema's own limit |
|---|---|
| Wire rope discard criteria | per the applicable wire rope standard (broken-wire count, diameter reduction) - confirm against the rope's own class and the class society's guidance |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Mooring winches fall under the deck machinery survey scope; class typically expects a brake holding/render test at the defined interval, wire rope certification/inspection records, and confirmation that the emergency release arrangement functions correctly.
Estimated lifetime: Hydraulic mooring winches in this size range commonly remain in service 20-25+ years with periodic brake, seal, and wire rope renewal; the frame and drum are normally the longest-lived components, with the gearbox and hydraulic components seeing the most wear.
