The YFM single-arm boat/raft davit crane is advanced lifting equipmentSingle Arm Raft Davit Crane specially designed for ships, offshore platforms, and emergency lifesaving scenarios. It integrates the dual functions of a davit and a crane.

 

The Davit Crane adopts an innovative single-arm structure with integrated hydraulic or electric drive systems, enabling fast and smooth release and recovery of lifeboats, life rafts, RHIBs, and various emergency equipment to ensure efficient personnel evacuation and material transportation in emergency situations.

 

Operators can remotely control the single-arm boat/raft davit crane through wireless remote control devices for flexible and convenient manipulation. Crew members can easily release and operate the winch handbrake inside the boat via steel cables connected to the winch brake arm and cable reel or perform relevant operations on the deck, significantly enhancing operational convenience and safety.

 

This boat lifting equipment strictly complies with the IMO and the International Convention for the SOLAS standards, making the single-arm boat/raft davit crane a trustworthy and preferred product in maritime safety.

The Core Advantages of single-arm boat/raft davit cranes

 

1. Compact Design and Flexible Adaptabilitysingle arm raft davit crane

- The single-arm structure of davit cranes saves deck space and is suitable for various ship types (merchant ships, cruise ships, naval vessels) and offshore platforms.

- Modular design supports customized loads (500kg–3000kg), working radii (2m–6m), rotation angles (0°–270°), and extension lengths to meet diverse scenario requirements.

 

2. Exceptional Safety Performance

- The single-arm boat/raft davit cranes have a dual braking system, overload protection, and emergency manual release device to ensure operational safety under extreme conditions.

- Protection rating: IP66/IP67 (waterproof and dustproof).

- Certified by ISO 9001 quality management system and classification societies such as DNV/GL and ABS to ensure global compliance.

 

3. All-Weather Durability

The body of the single-arm boat/raft davit crane is constructed from high-strength weather-resistant steel, with a surface treated by hot-dip galvanizing or epoxy coating. This offers salt spray corrosion resistance up to C5-M grade.

- Operates in extreme temperatures from -30°C to +55°C, withstanding harsh marine environments.

 

4. Intelligent Control Experience

- Optional wireless remote control/panel control for real-time monitoring of load status and equipment operation parameters.

- Low-noise operation and a maintenance cycle of up to 12 months reduce full lifecycle costs.

- Drive modes: hydraulic/electric.
