What is a marine knuckle boom crane?

A marine knuckle boom crane is a hydraulic crane with a folding boom structure designed for offshore and marine operations. Its compact design allows flexible lifting and precise cargo handling in limited spaces.

Where are marine knuckle boom cranes used?

Marine knuckle boom cranes are widely used on offshore vessels, workboats, supply vessels, fishing vessels, ports, shipyards, and marine engineering platforms for cargo handling and equipment lifting.

What are the advantages of a knuckle boom crane compared with a straight boom crane?

The folding boom design provides better flexibility and requires less installation space. It allows operators to perform lifting operations closer to the vessel and is suitable for complex marine working environments.

Can marine knuckle boom cranes be customized?

Yes. The crane can be customized according to lifting capacity, outreach, installation requirements, hydraulic system, control method, and marine working conditions.

PRODUCT INTRODUCTION

The Marine Knuckle Boom Crane is a deck lifting solution featuring an articulated folding boom design. Its core design incorporates a "knuckle" joint between the main and secondary booms, enabling the boom to fold inward like a finger. This significantly reduces the crane's overall footprint in the stowed position, freeing up valuable deck space. Compared to traditional straight or telescopic boom cranes, the knuckle boom design allows for higher lifting capacities at shorter working radii, offering a more compact structure, lighter self-weight, greater load ratio, and the ability to perform precise cargo handling and positioning in confined spaces.

FEATURES

Superior Articulation: Features multiple hinged joints that mimic arm movements, allowing it to easily navigate obstacles or reach into cargo holds.

Maximum Space Efficiency: Its compact, foldable structure offers exceptional adaptability on narrow or crowded vessel decks.

Reduced Load Swing: By controlling the boom directly via hydraulic cylinders, load sway is minimized, significantly enhancing operational safety.

All-Sea State Adaptability: With a low center of gravity and stable operation, it is perfectly suited for provisioning or salvage tasks in rough sea conditions.
