The 66kN@2m – 18kN@8m Marine Hydraulic Knuckle Crane is an essential lifting solution for modern vessels. Its innovative articulated boom design provides exceptional flexibility in confined shipboard spaces while maintaining impressive load capacity at varying reaches.
Key Features:
-
Variable Capacity: 66kN maximum load at 2m reach, 18kN at 8m reach
-
Space-Optimized Design: Articulated joints enable compact folding (60% reduction in stowed size)
-
Marine-Specific Engineering: Designed for saltwater environments and vessel motion
-
Precision Control: Proportional hydraulic controls for smooth operation
Typical Applications:
-
Offshore supply vessel operations
-
Deck cargo handling
-
Equipment maintenance
-
Crew transfer operations
-
Emergency rescue systems
