As a necessary special lifting device for ships, the boat davit shoulders the critical mission of lowering and hoisting lifeboats and workboats, with its performance directly impacting maritime life safety and operational efficiency. Maxtech, a factory in marine engineering equipment, introduces boat davits integrated with high-speed constant tension winch systems, shock absorption systems, and anti-swing systems, reshaping maritime safety standards through technological innovation.
I. Core Systems: Dual Guarantees for Safety and Efficiency
1. High-Speed Constant Tension Winch System
Equipped with an automatic centrifugal clutch and multiple interlocking safety devices, the winch maintains constant tension during hoisting (18m/min) and lowering (~48m/min). When the motor stops, the clutch disengages automatically to avoid overload impact; during manual winching, the pawl mechanism and limit switches form dual protection against accidental operations.
2. Shock Absorption System
The davit arm system uses welded marine steel plate box structures, combined with a weight cam brake and centrifugal speed limiter, to automatically buffer impact loads when lowering the boat. For example, when the wire rope lowering speed reaches 50m/min, the speed-limiting block contacts the body via centrifugal force, stabilizing the speed within a safe range and reducing hull sway.
3. Anti-Swing System
The davit arm tip is fitted with a wire rope anti-deviation device, ensuring the cable does not disengage from the pulley groove even when the ship lists 20°; the check valve in the hydraulic system regulates the davit arm rotation speed, with 360° full slewing design to precisely control boat swing, adapting to handling needs in harsh sea condition.
Take 23K boat davit as an example:
The main technical parameter:
| SWL | 23KN |
| Lifting load | 14KN |
| Slewing load | 14KN |
| Slewing radius | 3.8m |
| Boat Launching speed | 18m/min |
| Boat Lowering speed | 48m/min |
| Hoisting height | 20m |
| Pump station slewing angle | ＜330 ° |
| Accumulator slewing angle | ＜110 ° |
| Electrical energy slewing speed | 0.6~0.8 r/min |
| Accumulator slewing speed | ≥0.25 r/min |
| Drum rope capacity | 30m |
II. International Certifications and Product Advantages: Maxstate’s Technical Edge
1. Comprehensive Classification Society Certifications: Products are certified by international authorities including BV, CCS, ABS, strictly following API-2C standards and ship registration codes.
2. Modular Design and Efficient Service: On-site installation and commissioning take only 2-3 days, with engineers providing full guidance; the hydraulic system supports accumulator emergency oil supply, meeting the convention requirement of "independent of ship power".
3. Customized Solutions: Tailored to load requirements (3T@39M, 10T@15M, 35T@6.5M configurations) and ship layouts, offering left/right models for ocean-going cargo ships, offshore platforms, and other scenarios.
III. Invitation to Explore: On-Site Verification from Technology to Scenario
