Gravity Luffing & Rolling Davit System: Uncompromising Safety and Versatile Performance

Ensure the highest standards of safety, operational efficiency, and spatial optimization on your vessel or offshore platform with our state-of-the-art Gravity Luffing & Rolling Davit System.

Designed for the critical launch and recovery of lifeboats, rescue boats, workboats, tenders, and other essential equipment, this advanced davit combines the inherent reliability of gravity-based lowering with the flexibility of luffing and rolling capabilities. It represents the pinnacle of marine engineering, providing a robust, compliant, and user-friendly solution for demanding marine environments.

Key Features:

• Gravity Lowering Mechanism:
  • Enables safe and rapid launch of boats/equipment solely by gravity, independent of external power supply.
  • Critical for emergency situations, ensuring deployment even in the event of power failure.
  • Controlled by a self-braking winch system for precise and smooth descent.
• Luffing Capability:
  • Hydraulically actuated davit arm allows for adjustable outreach, moving the boat clear of the vessel's side and potential obstacles.
  • Provides optimal positioning for launch and recovery, even in adverse sea conditions or varying freeboard.
• Rolling/Traversing System:
  • Integrated with a robust track system (deck-mounted rail) allowing the entire davit structure to traverse along the deck.
  • Offers unparalleled flexibility, enabling launch and recovery from multiple positions or servicing multiple lifeboat/rescue boat stations with a single davit.
  • Maximizes deck space by allowing the davit to be stowed out of the way when not in use.
• Robust Marine-Grade Construction:
  • Fabricated from high-strength marine-grade steel (or optional stainless steel/duplex for enhanced corrosion resistance).
  • Designed and built to withstand harsh marine environments, including extreme temperatures, high humidity, and corrosive saltwater.
  • All critical components are protected against ingress of water and foreign particles.
• Advanced Hydraulic System:
  • Powers the luffing, rolling, and hoisting functions with precision and reliability.
  • Features a dedicated hydraulic power unit (HPU) with redundant systems and emergency manual operation capabilities.
• Intuitive Control System:
  • Ergonomic control panels with clear indications for local and remote operation.
  • Option for wireless remote control for enhanced operator safety and visibility.
  • Integrated diagnostics and alarm systems for proactive maintenance and fault finding.
• Integrated Safety Measures:
  • Overload Protection: Prevents lifting beyond Safe Working Load (SWL).
  • Limit Switches: Automatic cut-offs for maximum/minimum luffing, rolling, and hoisting positions.
  • Emergency Stop Buttons: Strategically placed for immediate system shutdown.
  • Anti-Pendulum System (Optional): Stabilizes the boat during hoisting and lowering, particularly in rough seas.
  • Manual Override: Hand pump for hydraulic functions in case of power loss.

Unrivaled Benefits:

• Superior Emergency Readiness: Immediate, power-independent gravity lowering ensures swift and safe deployment of life-saving appliances when every second counts.
• Exceptional Operational Flexibility: The combination of luffing and rolling allows for optimal positioning, overcoming deck obstructions, and servicing multiple stations, adapting to diverse operational scenarios.
• Enhanced Crew and Equipment Safety: Multiple safety features and robust construction minimize risk to personnel and valuable assets during critical operations.
• Optimized Deck Space Utilization: The rolling feature allows the davit to be positioned exactly where needed and then stowed, freeing up valuable deck space for other operations or cargo.
• Durability and Low Maintenance: Constructed from premium materials with a focus on longevity, requiring minimal maintenance even in the most challenging marine conditions.
• Global Compliance: Fully certified to meet international maritime regulations, ensuring seamless operation worldwide.

Applications:

• Lifeboat and Rescue Boat Davits: The primary application for SOLAS-compliant emergency deployment.
• Workboat and Tender Davits: For efficient launch and recovery on merchant vessels, cruise ships, and superyachts.
• Offshore Platform Davits: Reliable for personnel transfer and equipment handling on oil rigs, FPSOs, and wind farms.
• Naval & Coast Guard Vessels: For demanding military and patrol operations requiring versatile launch capabilities.
• Scientific Research Vessels: Handling of ROVs, AUVs, and other scientific instrumentation.
• Provision & Cargo Handling: For lighter cargo operations where precise positioning is key.

Safety & Compliance:

Our Gravity Luffing & Rolling Davit Systems are designed, manufactured, and tested in strict accordance with the latest international maritime regulations and standards, including:

• IMO SOLAS (International Convention for the Safety of Life at Sea)
• LSA Code (International Life-Saving Appliance Code)
• Relevant Classification Societies: Fully approved by major societies such as Lloyd's Register (LR), DNV (Det Norske Veritas), American Bureau of Shipping (ABS), Bureau Veritas (BV), RINA, NK, CCS, and others as required.
• EU Machinery Directive

All units undergo rigorous factory acceptance testing (FAT) and optional site acceptance testing (SAT) to guarantee performance and reliability.
