3T Offshore Knuckle Boom Crane

3T Offshore Knuckle Boom Crane

Unmatched Flexibility & Cost-Efficiency for Demanding Marine Operations

OUCO’s 3T Offshore Knuckle Boom Crane is engineered to deliver superior performance in the most challenging marine environments. Designed for Sea Condition Grade 4 (wave heights up to ~2 meters), this crane combines exceptional flexibility, robust durability, and operational cost-effectiveness, making it the ideal solution for offshore platforms, vessels, and marine support ships. With a 3-ton lifting capacity and adjustable working radius (2.5–15 meters), it excels in load transfers, supply handling, and subsea operations while minimizing deck space usage.

Key Advantages & User Benefits

1.Unparalleled Flexibility in Confined Spaces

The articulated knuckle boom design allows the jib to fold inward, reducing the crane’s footprint and enabling operations in tight deck zones. This design minimizes pendulum motion during load engagement, enhancing safety and precision when working near vessel structures.

360° continuous slewing (0.8–1.0 r/min) and hoisting speeds of 18–20 m/min ensure rapid cargo transfers and precise positioning, critical for time-sensitive offshore tasks.

2.Superior Cost-Efficiency

Unlike traditional cranes, OUCO’s knuckle boom crane requires minimal maintenance due to its sealed hydraulic circuits and corrosion-resistant coatings. Its energy-efficient hydraulic system reduces power consumption, lowering operational costs by up to 30% compared to conventional models.

The compact design eliminates the need for extensive deck modifications, saving installation costs and maximizing space utilization on vessels and platforms.

3.All-Weather Reliability

Engineered with oil-filled cylinders, marine-grade coatings, and sealed hydraulic systems, the crane withstands harsh saline environments and dynamic sea motions. It maintains stable performance in temperatures from -20°C to +50°C (optional -40°C package available).

Fail-safe brakes, overload protection, and emergency-stop functionality ensure operational safety in critical conditions, aligning with ISO and maritime safety standards.

4.Advanced Control Systems

Operators can choose between radio remote control and onboard console stations for flexible operation. Real-time monitoring systems provide data on load weight, boom angle, and environmental conditions, reducing human error and enhancing efficiency.
