A folding boom marine crane is a type of crane installed on ships, platforms, or offshore facilities. Its boom can be folded, stowed away when not in use to save space, and extended to the required length during operation. It is used for loading and unloading cargo, lifting equipment, or transporting personnel.
This type of crane is commonly found on cargo ships, fishing vessels, offshore platforms, and more. The folding design allows it to occupy minimal deck space during navigation or when not in use, while still maintaining high operational flexibility.
Space-saving
The boom can be folded and stowed, minimizing deck space usage during navigation
Flexible operation
Multi-joint folding design enables work in complex and confined environments
Quick response
Rapid deployment and stowage, ideal for frequent operation needs
Compact structure
Low center of gravity, minimizing impact on vessel stability
Versatility
Can be equipped with various attachments to handle cargo, personnel, and equipment lifting
Easy maintenance
Compact design with centralized service points
Durable construction
Main structure uses high-strength marine-grade steel with strict anti-corrosion treatment (such as high-performance marine coatings) to resist salt spray, humidity, and UV damage for long service life
Loss prevention
Reduced collision risk when stowed means fewer repair costs and less operational downtime
Standard safety features
Overload protection system, hydraulic locking device, and emergency manual pump
Flexible configuration
Multiple capacity options (e.g., 2 to 20 tons), with customizable boom length, rotation angle (full or partial slewing), and control methods (deck operation, remote control, etc.) to meet specific vessel requirements
Comprehensive certification
Designed and manufactured to comply with relevant international marine standards and regulations, with available classification society certifications (ABS, DNV, GL, CCS, etc.) to support newbuild or retrofit projects
For vessels with limited space such as tugboats, supply ships, research vessels, fishing boats, and medium-sized yachts, this folding boom marine crane is an ideal choice for optimizing layout due to its compactness and flexibility.
Workboats and Engineering Vessels
Fishing Vessels
Transport and Supply Ships
Specialized Vessels
• Firefighting and rescue ships
• Diving operation vessels
• Scientific research ships
Yachts and Luxury Cruise Ships
Offshore Platforms and Support Vessels
Selection Recommendation: If deck space is limited but frequent lifting operations are required, a folding boom crane is the ideal choice; for ultra-heavy lifting or extended operating radius requirements, other types of cranes should be considered.
