8Ton Folding Boom Marine Crane

8-Ton Folding Boom Marine Crane (FF160KC-4A)

Shipboard lifting operations often face challenges regarding cramped spaces and the large footprint required for equipment deployment; conventional cranes often lack the operational precision needed for variable offshore conditions. As a proven marine knuckle boom crane, the FF160KC-4A offers a lightweight lifting solution tailored for shipboard environments. It significantly reduces its footprint when stowed—ensuring efficient use of limited deck space—while reliably handling various offshore material lifting tasks.

This 8-ton folding boom marine crane (also classified as a knuckle boom crane) features a rated lifting moment of 16 ton-meters, a maximum lifting capacity of 8,000 kg, a maximum working radius of 9,680 mm, and a maximum lifting height of 11.2 m. It supports 360° continuous rotation and utilizes an integrated vertical hydraulic control structure, ensuring smooth operation and precise control. Compared to telescopic boom cranes, the folding boom design offers superior stowage advantages, making it ideal for vessels with limited deck space—such as service vessels, workboats, offshore platforms, and fishing boats—for tasks like cargo transfer, catch loading/unloading, and lifting spare parts. We also supply other lifting and grabbing equipment, such as grabs and forestry cranes (timber grabs), to meet diverse customer procurement needs.

Product Features

1. Features a 360° continuous rotation design and a compact four-section folding boom; weighs only 2,650 kg; easy flange-base installation makes it suitable for most ship deck retrofits.

2. Hydraulic system specifications: 28 MPa rated pressure, 40 L/min flow rate, 160 L internal oil tank, and 22 kW recommended power input; clear load charts ensure safe and controllable lifting operations.

Usage Tips

1. Before actual lifting, verify the rated load capacity for the current working radius against the load chart; overloading is strictly prohibited. It is recommended to reduce the lifting load during rough sea conditions.

FAQ

Q1: Can this Marine Knuckle Boom Crane be installed directly onto the deck of a standard fishing vessel?

A1: Yes, the equipment utilizes a standard flange base mounting method. However, the deck's load-bearing capacity must be calculated beforehand, and deck reinforcement may be required if necessary; please refer to the drawing dimensions for installation.

Q2: How does its routine maintenance compare to that of a telescopic boom crane?

A2: Maintenance is straightforward; key tasks include regularly checking the hydraulic oil level, seals, and the lubrication status of the slewing bearing. It is recommended to change the hydraulic oil according to the operating cycle to minimize valve wear.

Q3: Besides the crane itself, can you also supply models such as grab cranes or forestry cranes (log loaders)?

A3: Yes. In addition to knuckle boom cranes, our product range includes ship telescopic boom cranes, grab cranes, and forestry cranes (log loaders); you can request a bundled quote for these items.

Q4: What after-sales services are included?

A4: Drawings and load parameter data are provided upon delivery. We offer remote technical support, including guidance on installation, commissioning, and troubleshooting, as well as long-term supply of wear parts.
