Fuman’s Marine Knuckle Boom Crane range delivers reliable, compact lifting performance for vessels, combining the flexibility of a knuckle boom crane with rugged marine-grade design. Designed specifically for shipboard and offshore use, each unit offers full rotation, tight folding profile, corrosion-resistant coatings, and precision load control. Ideal for marine crane applications, it handles cargo, supplies, and equipment in confined deck spaces—unlike straight booms, the articulated boom can maneuver around obstacles while maintaining high lifting capacity.
Advantages of Knuckle Boom Marine Crane：
1. Expand space utilization: The boom can be folded and retracted, occupying less deck space when not in operation, making it easier for the ship to load other cargo or equipment; when in operation, it can be unfolded through the folding joints to complete lifting in a narrow deck area (such as vertical lifting of cargo in the cabin).
2. 360 rotation + multi-directional amplitude change: The boom can rotate all around, and with the pitch and telescopic movements of the folding joints, it can achieve "three-dimensional" operation and adapt to dynamic environments such as ship swaying and wave fluctuations.
3. High-strength material structure: The boom is made of high-strength alloy steel or low-temperature steel, with good tensile strength and fatigue resistance, ensuring long-term use without deformation under frequent lifting operations. The surface is sandblasted and coated with marine engineering-grade anti-corrosion coating to effectively prevent erosion by marine environmental factors such as salt spray, moisture, and sunlight. All parts used meet the standards of maritime equipment, have strong wear resistance and weather resistance, low equipment failure rate, simple maintenance, and long service life.
4. Adapt to various ship structures: Lightweight design Compared with large fixed cranes, folding arm cranes are lighter and can be installed on small and medium-sized cargo ships, engineering ships, fishing boats, etc., without major changes to the hull structure. It has strong supporting capabilities and can be expanded into a variety of functional operating platforms, such as ship grab buckets for loading and unloading bulk cargo, hanging baskets for rescue and transportation, etc.
