Marine jib cranes are essential lifting solutions designed for vessels, offshore platforms, ports, and marine engineering environments. NYBON provides a full range of marine jib cranes with robust construction, corrosion-resistant materials, and reliable hydraulic or electro-hydraulic drive systems. Whether mounted on the deck of a cargo ship or installed on a workboat for offshore supply operations, our cranes ensure safe and efficient lifting in harsh marine conditions.

Types of Marine Jib Cranes

Knuckle Boom Crane Ship Jib Crane

1. Marine Deck Jib Crane (Straight Boom)

Marine deck jib cranes—sometimes called ship deck cranes or straight-boom jib cranes—are the most common lifting solutions installed on vessels. They feature a rigid boom, large lifting capacity, and long outreach, making them ideal for cargo handling, ship-to-ship transfer, and marine construction.

  • Heavy-duty welded steel structure for demanding maritime use. Long outreach for extended cargo handling ranges. Electro-hydraulic or hydraulic drive for smooth and powerful operation

  • Slewing mechanism with 360° continuous rotation. Suitable for 5–100+ ton capacity requirements

Applications:
Cargo ships, bulk carriers, barges, research vessels, engineering ships, and port service vessels.

Marine Folding Crane Boom Telescopic Jib Crane

2. Knuckle Boom Marine Crane (Folding Boom Crane)

Knuckle boom marine cranes—also known as foldable marine cranes—use an articulated boom that can bend like a knuckle, allowing them to fold into a compact shape. This makes them perfect for vessels with limited deck space or for offshore supply operations that require flexible lifting.

  • Foldable boom design for compact storage. Precise load handling in tight operational areas

  • High lifting capacity with advanced hydraulic control. Excellent for offshore and subsea applications

  • Optional remote control and load monitoring system

Applications:
Offshore supply vessels (OSVs), deck service operations, aquaculture, oil & gas platforms, and small or mid-size workboats.

3. Customized Marine Jib Crane

Many vessels require a crane tailored specifically to their deck layout, lifting requirement, or environmental conditions. NYBON specializes in designing custom marine jib cranes that perfectly match your operational needs.

Customization Options:

  • Tailor-made boom length, outreach, and pedestal height; Marine-grade anti-corrosion treatment for long-term sea exposure

  • ABS / DNV / BV / LR / CCS class approval upon request; Optional explosion-proof design for hazardous zones

  • Hydraulic, electro-hydraulic, or full electric drive; Winterization packages and stainless-steel components

If you have vessel drawings or a lifting plan, our engineering team can design a crane precisely for your marine project.

FAQ — Marine Jib Cranes

1. What is the difference between a knuckle boom marine crane and a standard deck jib crane?

A standard deck jib crane uses a straight, fixed boom structure designed for heavy lifting and long outreach.
A knuckle boom (foldable) crane has articulated arms that can bend, fold, and operate in confined spaces with greater flexibility. Both are marine jib cranes, but they serve different operational needs.

2. Can your marine jib cranes be certified by class societies?

Yes. NYBON marine cranes can be built to meet the standards of BV, ABS, DNV, LR, CCS, and other major classification societies, as per customer requirements.

3. How do you protect the crane from saltwater corrosion?

We apply a multi-layer marine protection system: sandblasting, Zinc-rich primer, Epoxy intermediate coating, UV-resistant polyurethane topcoat, and Hot-Dip galvanizing. Stainless-steel components are optional.

4. Can NYBON customize the crane to fit my vessel’s layout?

Absolutely. We can customize: Pedestal height, Boom length, Outreach, Hydraulic system, Mounting structure, Slewing mechanism, Working load requirement. Our engineers will design a solution based on the exact deck drawings.

5. What power systems are available?

NYBON provides: Electro-hydraulic systems (most common), fully hydraulic systems, Electric drive systems, and explosion-proof versions

6. Can marine jib cranes be customized?

Absolutely. NYBON offers full customization, including:

Boom length, Slewing angle, Travel distance, Hoist type, Mounting style, Explosion-proof and stainless-steel versions
