However, the compact features of these cranes do not compromise their performance. Our hydraulic marine knuckle boom cranes have a lifting power ranging from 0.5t to 150t.

What is a Marine Knuckle Boom Crane?

Knuckle boom cranes are like the Swiss army knives of cranes. Their secret? A multi-jointed arm that folds at a hinge, much like a knuckle. This design allows them to bend and twist, reaching into tight spaces that would stump other cranes.

These versatile workhorses are popular on boats and other marine vessels. Their telescopic booms can extend far and retract neatly, while the knuckle joints provide precise control. This makes them perfect for delicate tasks like subsea operations, lifting materials around the ship, or even assisting with scientific research.
