Hydraulic Articulating Crane

The articulating knuckle boom crane, also known as a folding boom crane or articulated jib crane, is engineered based on the kinematic principles of the human arm. Through multi-section booms connected by articulated joints, the equipment can flex and fold like a finger, enabling "dead-angle-free" precise lifting in confined spaces.

Designed for harsh offshore environments and complex industrial scenarios, this crane series delivers exceptional maneuverability and robust lifting power-whether for deck cargo supply, offshore platform maintenance, or precision assembly in workshops.

1. Superior Maneuverability – The Ideal Choice For Confined Spaces

Unlike traditional straight-boom cranes that require large slewing radii, our articulating knuckle boom crane features a folding arm design that reduces stowage footprint by up to 40% when non-operational. This makes it the ideal solution for vessels with cramped deck space, congested workshops, or narrow urban construction sites. The boom can flexibly navigate around obstacles, achieving precise positioning in complex environments.

2. Wide Lifting Capacity Range – Ready For Heavy Loads

Our product line covers a broad spectrum of lifting capacities, ranging from light-duty 2.3-ton models to heavy-lift 250-ton units, with customization available up to 2000 tons. With a maximum working radius of up to 36 meters and continuous 360° slewing capability, the crane ensures efficient handling of heavy cargo and equipment maintenance from any angle.

3. Intelligent Hydraulic System – Smooth And Precise Operation

Equipped with advanced load-sensing hydraulic systems and proportional control technology, the crane enables efficient compound movements while significantly enhancing operational precision and micro-motion control. Optional Active Heave Compensation (AHC) effectively counteracts vessel heave motion (compensation accuracy up to ±2.5m) , ensuring stable load hoisting even in harsh sea states (Sea State 4-5) for safe deepwater resupply and personnel transfer.

4. Military-Grade Anti-Corrosion – Built For Harsh Environments

Designed for corrosive marine and chemical environments, the crane features rigorous surface treatment, including ISO 12944 C5-M heavy-duty epoxy coating and 316L stainless steel hydraulic fittings. All critical electrical and hydraulic components are hermetically sealed with IP68 protection rating, resistant to salt spray, humidity, and extreme temperature variations (-20°C to +40°C), ensuring lifecycle reliability in the toughest conditions.

5. Multi-Layer Safety Redundancy – Protecting Personnel And Assets

Safety is our top priority. The system integrates multiple protection mechanisms:

• Overload cut-off protection with response time ≤0.5 seconds.
• Anti-collision systems to prevent impacts in complex workspaces.

• Dual-circuit hydraulic braking and emergency manual relief for safe shutdown in emergencies.

• Man-riding certification available, meeting stringent safety standards for personnel transfer on offshore platforms.
