1.6Ton Flange Mounted Knuckle Boom Marine Crane

1.6-Ton Flange-Mounted Marine Knuckle Boom Crane

Deck space on ships is often limited, and standard cranes can be bulky and take up significant room when stowed; finding suitable equipment for supply lifting on small vessels has long been a challenge. Many customers struggle to choose between a telescopic boom crane and a knuckle boom crane, yet wish to avoid the higher costs associated with ship-grade telescopic boom cranes. Our FF022KC-3A hydraulic knuckle boom crane is designed specifically for these scenarios. It features a maximum lifting capacity of 1,600 kg (1.6 tons), a lifting moment of 2.2 ton-meters, a 330° slewing angle, a maximum working radius of 3,250 mm, and a maximum lifting height of 4.7 meters. Weighing only 350 kg and featuring a compact folded profile, it supports operation by personnel standing right next to the unit—making it ideal for lifting materials and supplies on fishing boats, workboats, and yachts. We also offer other models, such as grab cranes and forestry cranes (log loaders), to handle specialized tasks like material grabbing and timber handling.

1. Product Features: ① Flange-mounted installation eliminates the need for complex pedestal bases, reduces deadweight, and minimizes deck space usage; ② 330° slewing capability; the knuckle boom design makes it easier to maneuver around deck obstacles like piping and railings; ③ Hydraulically driven with an integrated control layout for easy operation.

2. Usage Tips: As this is a marine knuckle boom crane, it is susceptible to salt spray corrosion; please rinse the surface with fresh water after each use. Do not exceed the rated lifting capacity, and always double-check the flange mounting bolts before operation.

FAQ

Q1: Can this directly replace a ship-grade telescopic boom crane?

A1: The two types of cranes are suited for different applications. This knuckle boom crane excels in compact folding and obstacle avoidance, though its maximum outreach is less than that of a telescopic boom crane. It is more suitable for short-range shipside replenishment; however, if long-reach operations are required, a telescopic crane is the preferred choice.

Q2: What should be the focus of routine maintenance?

A2: Daily checks should focus on inspecting hydraulic hoses for leaks, regularly lubricating the slewing bearing, and checking the paintwork for rust protection. Hydraulic oil should be changed according to the schedule, and grease applied to articulation points; maintenance intervals should be shortened for equipment used in high-salinity coastal environments.

Q3: What after-sales support is available?

A3: Installation drawings and operation manuals are provided with the shipment. We handle issues related to original manufacturing quality within the warranty period, supply replacement parts such as seals and hydraulic valves, and offer remote technical assistance for troubleshooting.

Q4: Can a grapple be retrofitted later to convert it into a grab machine or a forestry crane (log loader)?

A4: The hydraulic system includes reserved ports for expansion, allowing for the optional installation of a grapple. However, adding an attachment alters the load characteristics; the lifting moment must be recalculated to ensure it does not exceed the equipment's rated specifications.
