Single-arm Slewing Davit Crane
--- A high-precision rotating lifting solution designed for modern ships, offshore platforms, and ports.
The innovative Single-arm Slewing Davit Crane enables the safe and rapid deployment of lifeboats, life rafts, RHIBs, materials, and equipment. This equipment strictly complies with international regulatory requirements such as the International Convention, making it a necessary solution for enhancing operational efficiency and safety assurance.
✅ Full-Rotation Precision Control
- Supports 360° free rotation (270° limit optional), with hydraulic/electric dual-drive modes, 40% torque improvement, and lifting positioning error <5cm.
- The single-arm articulated design reduces blind spots and perfectly adapts to narrow deck spaces, ship sides, and platform edges.
✅ High-lifting capacity, Durable, Maintenance-easy
- Load coverage: 500–5000kg (customizable). The high-strength alloy steel main body undergoes FNV fatigue resistance treatment, extending service life by 50%.
- Corrosion protection grade C6-M (ISO 12944), stable operation in extreme environments from -30°C to +70°C, with a maintenance interval of up to 18 months.
✅ Intelligent Safety Ecosystem
- Triple protection: redundant braking, dynamic overload limitation, and emergency manual release. The real-time monitoring system automatically locks abnormal sway.
- AI anti-sway system significantly improves lifting stability in wind and waves(Optional)
✅ Minimalist Integrated Deployment
- Modular pre-installed structures shorten shipyard installation cycles by 60% and are compatible with various ship types (cargo ships, cruise ships, military vessels), and fixed platforms.
- Provides full CE/DNV/ABS/LR/CCS certifications for unobstructed operations in global waters.
