The Norsafe LH luffing davit is specifically designed for safe and efficient launch and retrieval of totally enclosed life boats. It is intended for long term, reliable operation in harsh and hazardous marine and offshore environments. The davit system is designed in accordance with latest Solas and IMO requirements.
The davit is designed for a compact installation. It can normally be installed within two decks, and the length and width will not need more space than the boat itself.
The system provides:
- Gravity lowering of the loaded boat independent of external power supply.
- Recovery of the empty boat with crew of 3.
- Retrieval of the boat by manual hoisting.
