3.2Ton Flange Mounted Knuckle Boom

FF068KC-3A 3.2-Ton Flange-Mounted Knuckle Boom Crane

Operational areas such as decks and platforms often have limited space; many lifting devices risk colliding with surrounding structures when deployed, restricting their range of motion. After comparing various models, buyers often struggle to find a solution that balances stable load capacity, a lightweight design, and ease of installation. The FF068KC-3A 3.2-ton flange-mounted knuckle boom crane was developed specifically for these scenarios. Featuring a flange-mounted base and a fully slewing knuckle boom structure, it enables flexible material handling in tight spaces while delivering stable lifting performance—making it ideal for shipboard use and space-constrained lifting operations.

The FF068KC-3A is a 3.2-ton flange-mounted hydraulic knuckle boom crane with a maximum lifting capacity of 3,200 kg, a lifting moment of 6.8 ton-meters, a maximum working radius of 7.7 m, and a maximum lifting height of 8.5 m; the unit's total weight is kept to just 950 kg, and it utilizes an integrated standing control station. Unlike telescopic boom cranes, the knuckle boom design occupies less space when stowed. Compared to shipboard telescopic boom cranes, this marine knuckle boom is better suited for the frequent transfer of small materials on decks. The product line also supports attachments such as grabs and timber grapples, meeting diverse operational needs—including material handling and log loading—across ship decks, offshore platforms, and small-scale construction sites.

I. Product Features

1. Direct flange-base mounting requires minimal structural modification; supports 360° continuous rotation for a wide operational range.

2. Lightweight design with a total weight of only 950 kg; offers stable 3.2-ton rated lifting capacity while reducing the load on the carrier vessel.

3. Hydraulically driven with a foldable boom; capable of deploying and operating in confined spaces such as ship holds or narrow platforms.

II. Usage Tips

1. Consult the load chart before every lift to verify the safe working load at the current radius; overloading is strictly prohibited.

2. Rated hydraulic system pressure is 25 MPa; a 15 kW power unit is recommended, and the pump station specifications must match the equipment requirements.

III. FAQ

Q1: Can this marine knuckle boom crane be mounted directly onto a cargo ship deck?

A1: The flange base features standard mounting holes; it can be secured once the deck structure is reinforced. Additional anti-corrosion protection is recommended for long-term marine use.

Q2: What areas require the most attention during routine maintenance?

A2: Focus on regularly checking hydraulic hose fitting seals and slewing bearing lubrication; change hydraulic oil periodically to prevent impurities in the circuit from scratching valve components.

Q3: Can a grab attachment be installed on the main unit to replace a dedicated forestry crane (log grab)?

A3: The unit supports attachment changes; optional grabs allow for handling logs and bulk materials. However, if the primary application is timber handling, a dedicated forestry crane is the preferred choice.

Q4: What after-sales support is available?

A4: Warranty coverage is provided as per the contract; replacement parts are supplied for core hydraulic component failures during the warranty period, alongside installation guidelines and remote commissioning assistance.

Q5: What are the advantages of this knuckle boom crane compared to standard or ship-mounted telescopic boom cranes?

A5: The boom can be folded and stowed, taking up less space and offering flexible slewing, making it suitable for decks with limited room; telescopic boom cranes are better suited for long-range, straight-line extension and lifting operations. You can choose the appropriate type based on specific on-site conditions.
