Single Arm Slewing Boat/Raft Davit & Crane – Compact Launching and Lifting Solution for Lifeboats and Rafts

The Single Arm Slewing Boat/Raft Davit & Crane from CMEC FJCN is a multi-functional marine launching and lifting device designed for ships, offshore platforms, and coastal installations. It provides efficient handling of lifeboats, inflatable life rafts, and light equipment through its slewing arm structure, which allows horizontal rotation to the launch position before gravity- or hydraulic-powered lowering.

This compact unit is ideal for space-limited vessels and is commonly installed on cargo ships, passenger vessels, patrol boats, oil rigs, and offshore support vessels. With its 360° slewing capability and lightweight but robust construction, the Single Arm Davit offers exceptional performance in both emergency and routine operations.

It combines the functionality of a boat davit and a lightweight crane, providing dual-use capability that saves deck space and cost while complying with SOLAS and IMO safety standards.

Key Features and Benefits:

• Single-arm slewing structure – enables flexible operation and compact storage

• Dual function – serves as both lifeboat/raft davit and marine crane

• Manual, hydraulic, or electric operation – adaptable to different vessel systems

• Gravity-assisted or winch-controlled lowering – safe, reliable deployment

• Ideal for inflatable rafts, small rescue boats, or light cargo

• Rotating slewing base – efficient maneuvering to outboard position

• Corrosion-resistant materials – designed for long-term marine use

• Fully SOLAS, IMO, and LSA Code compliant

The unit includes a slewing base, single arm boom, lowering winch, and control system. The boom rotates to the launch side using a slewing motor or manual crank and lowers the boat or raft using gravity or hydraulic winch control. The lightweight structure simplifies installation and makes it suitable for smaller vessels or retrofit applications.
