Foldable Knuckle Boom Crane
OUCO’s foldable knuckle boom cranes deliver the precise maneuverability and robust power required for demanding marine and offshore operations. Combining versatile functionality, remote control capability, and personnel lifting support, this series stands as our most popular crane solution.
When these cranes are retracted, they fold down to a compact footprint—saving 40% of precious space on ships and offshore platforms compared to other crane types. Once deployed, their articulating boom design delivers a versatile range of boom lengths and lifting capacities (1 to 30 tons), making them well-equipped to handle all kinds of tasks. Our customers trust them for use across marine scenarios—like fishing vessels and work boats—energy installations such as wind turbines, and even indoor industrial settings.

A Foldable Knuckle Boom Crane maximizes available space through its unique articulating boom design, similar to truck-mounted cranes. This boom knuckles, folds, and extends, providing robust strength and exceptional flexibility for loading and unloading diverse cargo, tools, and equipment – even in confined workspaces. Its superior outreach flexibility ensures efficient lifting processes where space is limited.
Key Advantage: Space efficiency and maneuverability in tight areas.
Considerations: While highly versatile, folding mechanisms require regular maintenance, and these cranes are not designed for continuous heavy-duty cycles. Their lifting capacity at maximum range is typically lower than conventional telescopic cranes.
Foldable knuckle boom cranes excel in space-constrained environments, making them ideal for diverse applications. In marine and offshore settings, they fit easily on various vessels such as workboats, service vessels, cruise ships, and fish farming vessels, and can also be used for subsea construction tasks like handling pipelines and ROV umbilicals. Additionally, they play a key role in shipboard logistics, supporting cargo handling, net deployment, and rescue operations on fishing boats, research vessels, and naval ships.
Moreover, in offshore drilling and wind farm support, these cranes are essential for routine maintenance, personnel and supply transfer, and equipment repairs.
Beyond marine contexts, in industrial and onshore settings, they are invaluable wherever limited space and flexible reach are required for material handling—this includes applications like bridge repair, lifting debris, rescue operations, and agricultural tasks.
Foldable knuckle boom crane consists of features that make it highly ideal in any lifting and uplifting assignments:
- Corrosion protection
- Integrated with high hydraulic power pack
- High strengthen cranes
- It perfectly suits different types of marine vessels.
- High-efficiency
- It has an interrupted slewing system.
Foldable Knuckle Boom Crane
The foldable knuckle boom crane, the most muscular compact structure, is perfect for heavier lifting and uplifting.
Due to its excellent mobility, high strength, and consistency.
Stiff Knuckle Boom Crane
On the other hand, stiff knuckle boom cranes use a hydraulic winch to raise and down the object.
They have a steel arm crane that can lift straight up and down and place more loads in certain places.
Below are the visible benefits of using a foldable knuckle boom crane for your loading and unloading activities:
- Easier for loading and unloading property
- Higher level of mobility
- Long-life surface services
- Can operate whether on low or high temperature
- Safety enough in any lifting movements
- It only consumes low power energy
- Comprises with safety devices and alarms
