3.5T10M Knuckle Telescopic Boom Marine Crane
Engineered for modern marine operations, the OUCO 3.5T10M Knuckle Telescopic Boom Marine Crane delivers power, precision, and efficiency in a compact design. CCS-certified, it merges the flexibility of a knuckle boom with the extended reach of a telescopic boom—ideal for vessels with limited deck space needing broad operational coverage.
Unlike fixed-boom alternatives, its foldable knuckle design operates in confined areas and retracts neatly when idle, maximizing deck space. With a 10m maximum and 2.2m minimum working radius, it handles both near-deck tasks and extended offshore lifting, adapting seamlessly to supply vessels, fishing boats, and research ships for supplies, equipment, or cargo.
Powered by a high-efficiency hydraulic system, it achieves 15 m/min hoisting speed, 20m hoisting height, and 360° continuous slewing (0.6 r/min) for precise load positioning—even in Sea State 4 conditions. Its 50-second luffing time ensures responsive operation in offshore or port settings.
Constructed from high-strength marine-grade steel with multi-layer marine coating, it resists corrosion for long-term durability in saltwater environments. Premium hydraulic and electrical components from trusted global brands guarantee consistent performance and easy maintenance.
OUCO offers customization for lifting capacities, control systems (manual, remote, PLC-based), and finishes to match vessel needs.
Blending space-saving design, robust construction, and certified safety, this crane balances versatility, efficiency, and longevity—an intelligent choice for demanding marine applications.
