Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Load pin and bush wear | no generic dimensional limit applies to this safety-critical component; assess against the manufacturer's go/no-go gauge or stated wear allowance at the 5-yearly overhaul, not by estimation |
|---|---|
| Release trigger clearance | must be set per Palfinger's approved adjustment procedure for the LHR3.5 M2 and checked at each overhaul - never adjust by feel |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Subject to SOLAS III and LSA Code requirements for on-load release gear. Annual thorough examination and 5-yearly overhaul/load test by the manufacturer or an approved service provider is a class/flag requirement following the post-2013 LSA Code amendments addressing lifeboat release and retrieval system failures. Records must be kept in the ship's launching appliance maintenance record and produced at survey; any modification to the release gear requires manufacturer and class approval.
Estimated lifetime: Not measured in running hours - service life for on-load release gear of this type is governed by the mandatory 5-yearly overhaul/inspection regime rather than hours in use. Confirm any manufacturer-stated expected service life and replacement recommendation against Palfinger's technical documentation and the applicable flag/class requirement.
