Brand: Henan Hengkun Crane Co., Ltd.
Applications: Offshore supply vessels, wind farm installation ships, salvage operations, and marine platforms requiring highly flexible, multi-functional lifting solutions for cargo handling, subsea equipment deployment, and personnel transfers in harsh maritime environments.
Our Knuckle Boom Telescopic Crane combines the articulated flexibility of a knuckle boom with the extended reach of a telescopic arm, offering unparalleled versatility for marine lifting tasks. Designed to operate in extreme offshore conditions, this crane delivers precision, durability, and compact storage, making it ideal for dynamic vessel decks where space and adaptability are critical. With lifting capacities up to 150 tonnes, it excels in cargo logistics, ROV deployment, and heavy-load operations even in rough seas.
Hybrid Articulated-Telescopic Design
2–3 knuckle joints + 3–4 telescopic boom sections for maximum reach (up to 50 meters) and tight-space maneuverability.
Compact stowed configuration minimizes deck footprint.
Marine-Grade Durability
ISO 12944 C5-M anti-corrosion coatings and stainless steel components for saltwater resistance.
IP68-rated hydraulic systems and waterproof electrical enclosures.
Dynamic Motion Compensation
Active Heave Compensation (AHC) or Passive Motion Damping systems to stabilize loads in rough seas.
360° continuous slewing and ±30° luffing range for precise positioning.
Safety & Efficiency
Overload protection, dual braking systems, and emergency stop functions.
Regenerative hydraulics reduce energy consumption by 20–30%.
Multi-Functional Attachments
Compatible with hooks, grabs, personnel baskets, subsea tooling, or salvage grapples.
Remote control operation with anti-collision sensors and IoT diagnostics.
