3.5T10M Knuckle Telescopic Boom Ship Deck Marine Crane

Engineered to meet the diverse demands of modern marine operations, the OUCO 3.5T10M Knuckle Boom Telescopic Marine Crane delivers power, precision, and efficiency in a compact design. Certified by the China Classification Society (CCS), this crane combines the flexibility of a knuckle boom with the extended reach of a telescopic boom—making it ideal for vessels with limited deck space but requiring wide operational coverage.

Unlike conventional fixed boom marine cranes, this model features a foldable knuckle boom design, allowing it to operate in confined areas and retract neatly when not in use—maximizing valuable deck space. Its maximum working radius of 10 meters and minimum radius of 2.2 meters enable both near-deck operations and extended offshore handling, providing unmatched adaptability for lifting supplies, equipment, or cargo on supply vessels, fishing boats, and research ships.

Powered by a high-efficiency hydraulic system, the crane delivers a hoisting speed of up to 15 m/min and a hoisting height of 20 meters, ensuring smooth, fast, and safe lifting operations. The 360° continuous slewing capability and a slewing speed of approximately 0.6 r/min allow for precise load positioning even in dynamic sea conditions up to Sea State Grade 4. Its luffing time of about 50 seconds further supports responsive operation and control during offshore or port activities.

Constructed from high-strength marine-grade steel, the OUCO 3.5T10M crane offers superior corrosion resistance and long-term durability. Every surface is protected with multi-layer marine coating, ensuring reliability in harsh saltwater environments. Premium hydraulic components and electrical systems from trusted international brands guarantee consistent performance and easy maintenance.

OUCO supports a wide range of customization options, including different lifting capacities, control systems (manual, remote, or PLC-based), and finishes tailored to your vessel’s requirements.

Combining space-saving design, robust construction, and certified safety, this Knuckle Boom Telescopic Marine Crane is a smart investment for operators seeking a balance of versatility, efficiency, and longevity in demanding marine applications.
