Description

Gravity Overhead Rolling Type Davit – Efficient, Overhead Lifeboat Launching by CMEC FJCNThe Gravity Overhead Rolling Type Davit from CMEC FJCN is a reliable overhead launching system designed for lifeboats and rescue boats, offering space-saving installation and automatic gravity deployment.

The Gravity Overhead Rolling Type Davit by CMEC FJCN is a high-performance marine launching system designed to support the safe and efficient deployment of lifeboats and rescue boats from ships and offshore platforms. Mounted above the boat on an overhead beam, this davit uses a gravity-powered rolling mechanism to deliver smooth, controlled launches—especially useful in compact or enclosed deck areas.

Ideal for Totally Enclosed Lifeboats, Partially Enclosed Lifeboats, and Rescue Boats, this davit configuration allows the lifeboat to move along overhead tracks from a parked position to a launch-ready stance over the ship’s side. It is especially suited for passenger vessels, offshore platforms, container ships, and tankers that require space-saving solutions with dependable emergency functionality.

Key Features and Benefits:

• Gravity-powered rolling deployment – no external power needed

• Overhead track-mounted system – maximizes deck space and accessibility

• Manual and hydraulic winch operation for boat recovery

• Compact structure – ideal for vessels with limited side-deck area

• Self-locking and controlled descent with shock-absorbing features

• Anti-corrosion coated frame for long-term marine use

• Compliant with SOLAS, IMO, and LSA Code

The system includes an overhead beam, rolling trolleys, suspension blocks, winch assembly, and wire rope drum, with optional hydraulic or electric winch systems for enhanced hoisting. Once the launch command is given, the boat slides into position via gravity and lowers automatically—ensuring rapid evacuation with minimal crew input.

Technical Specifications:

• Working Load Capacity: 15–35 kN

• Lowering Speed: 0.3–1.0 m/s (regulated by load)

• Structure Type: Overhead beam with roller trolley system

• Material: Marine-grade carbon steel or stainless steel

• Surface Coating: Epoxy zinc primer and polyurethane topcoat

• Control Options: Manual, hydraulic, or electric recovery winch

• Compliance: IMO MSC.81(70), MSC.226(82), SOLAS, LSA Code

• Environmental Resistance: Salt spray, UV, and extreme temperatures

Designed for durability and ease of maintenance, CMEC FJCN’s Gravity Overhead Rolling Type Davit is factory-tested under full-load conditions and provided with complete documentation, spare parts kits, and crew training services. It is engineered to operate effectively even under adverse conditions, ensuring your lifeboat can always be launched without delay.

This davit is particularly favored for retrofits, where existing deck arrangements limit traditional davit types. Its overhead rail system ensures the lifeboat clears the ship’s structure before descent, making it a safe choice for modern vessel designs.
