Foldable Knuckle Boom Cranes are innovative lifting systems designed for high efficiency and adaptability in marine, offshore, and industrial environments.
Combining a compact, collapsible structure with robust performance, these cranes excel in confined spaces on vessels, offshore platforms, and wind farms, offering precise load handling for cargo, equipment, and personnel.
Their unique knuckle-joint design allows for flexible outreach adjustments, making them indispensable for dynamic workflows where space optimization and safety are paramount.
• Compact and Foldable Design
Engineered for space efficiency, these cranes feature a collapsible boom that minimizes footprint, enabling installation on vessels with limited deck space, such as service boats,fishing trawlers, and cruise ships.
Constructed from high-strength steel or corrosion-resistant alloys, they withstand harsh marine conditions, including saltwater exposure and extreme temperatures.
• High-Performance Specifications
Lifting Capacity
Ranges from 1.7 to 32 ton.
Outreach Flexibility
Adjustable telescopic booms extend up to 22m, with configurations tailored for precise load placement around obstacles.
Power Systems
Options include hydraulic, electric, or hybrid drives, with operating pressures up to 300 bar for seamless heavy-duty operations.
• Advanced Safety and Control
Integrated safety mechanisms such
Overload Protection Systems (MOPS/AOPS) and constant tensioning ensure stability during lifting.
Multiple control options
remote control, local control stations, and operator cabins, enhancing precision in challenging environments like offshore oil rigs.
Optional workman baskets and man-riding capabilities
enable safe personnel transfers for maintenance or emergency tasks.
Foldable Knuckle Boom Cranes are vital across maritime and industrial sectors:
• Marine Logistics
Load and unload provisions, cargo, and tools on service vessels, cruise ships, and fishing boats.
• Offshore Energy
Support equipment handling on FPSOs, oil rigs, and wind turbine installation vessels, with configurations for subsea operations.
• Aquaculture
Manage fish farming operations on large aquaculture vessels, including net handling and feed deployment.
• Emergency Response
Deploy life-saving equipment and stabilize operations during critical missions.
• Space Efficiency
Compact folding mechanisms reduce storage requirements, ideal for small vessels or crowded decks.
• Energy Optimization
Features like return oil utilization and regenerative hydraulics lower fuel consumption.
• Customization
Modular components allow tailored solutions, such as ATEX-compliant designs for hazardous zones or central greasing systems for low maintenance.
• Compliance
Certified to ISO, DNV, ABS, and Lloyd’s Register standards, ensuring global regulatory adherence.
• Proven Durability
Long-life surface treatments and corrosion protection ensure decades of reliable service in marine environments.
• Adaptive Functionality
From telescopic extensions to specialized attachments (e.g., grabs, rotators), these cranes adapt to evolving operational needs.
Foldable Knuckle Boom Cranes redefine material handling in maritime and offshore industries by merging compactness, power, and adaptability. Their ability to perform under extreme conditions-from fish farming vessels to high-stakes offshore platforms—makes them a strategic asset for businesses prioritizing efficiency, safety, and compliance.
