FF300TC-4A
Marine deck lifting operations often present challenges such as salt-spray corrosion and difficulties in aligning equipment with fixed mounting positions on the deck. Many clients, when choosing between a knuckle boom crane and a telescopic boom crane, are unsure whether the crane’s self-weight and lifting capacity are well-suited for their specific vessel. Our FF300TC-4A 12-ton flange-mounted telescopic boom marine crane is designed to address these issues through its secure, flange-based mounting system. This telescopic boom marine crane features a maximum lifting moment of 30 ton-meters, a rated lifting capacity of 12,000 kg, a maximum working radius of 15 meters, and a maximum lifting height of 15.6 meters. The unit weighs 4,050 kg and operates with a hydraulic system rated at 25 MPa pressure and a flow rate of 60 L/min. It supports 360° full-circle slewing, and operators can control the unit while standing right next to it—making it ideal for transferring deck cargo or hoisting maintenance equipment.
When selecting equipment, it is important to distinguish between types: marine knuckle boom cranes are better suited for compact spaces, while specialized units like grab cranes or forestry cranes (log-handling cranes) are designed for material or timber handling—purposes distinct from those of this telescopic boom crane.
1. Product Features: The flange base comes with pre-drilled standard bolt holes, ensuring straightforward alignment and installation on board. A comprehensive load chart is provided, clearly outlining lifting limits for various boom angles and radii, which helps on-site personnel maintain safe load operations.
2. Tips: Always refer to the load chart during marine operations, and reduce the working radius when sea conditions are rough. Before starting work each day, inspect the hydraulic lines and check the tightness of the bolts at the slewing mechanism.
Q1: What types of vessels is this telescopic boom marine crane suitable for?
A1: It is typically installed on the decks of workboats, offshore barges, and service/maintenance vessels for lifting spare parts and tools. If you frequently handle loose cargo, this model is not recommended; a "Grab Machine" (crane equipped for grab operations) would be a better choice.
Q2: What should be the focus of routine maintenance in a high-salinity coastal environment?
A2: Rust prevention is the top priority; ensure hydraulic oil is changed on schedule. Telescopic boom wear pads and slewing ring seals are consumable parts—check them regularly. In areas with high salt-spray exposure, inspect the paintwork frequently and touch it up promptly if needed.
Q3: What documentation is provided with the shipment, and how is after-sales support handled?
A3: The shipment includes a load chart, as well as printed installation and operation manuals. During the warranty period, we provide remote technical guidance; wear parts and spare components can be ordered separately.
Q4: Can this crane be converted into a knuckle-boom (articulated) type?
A4: This unit features a telescopic boom structure and cannot be converted into a knuckle-boom type. If you require a knuckle-boom model, please consider our "Marine Knuckle Boom Crane" series.
