Medium Deck Telescopic folding boom Crane is installed on the deck base of cargo ships, using hydraulic drive, featuring multi-jointed folding and telescopic arm with infinite range adjustment/radius change; it achieves ample coverage and precise positioning within limited deck space, serving as the main loading and unloading equipment for bulk carriers, multi-purpose ships, roll-on/roll-off ships, and engineering ships, while also supporting ship-to-ship (STS) replenishment and offshore engineering lifting. This type of deck crane combines flexibility and load capacity, making it particularly suitable for operations on space-limited decks.
Why Choose Telescopic Foldable Design?
Small Size, Large Range: The most significant advantage of the telescopic jib design is "small footprint, large operating range." This means it can cover a wider working area without occupying excessive deck space, making it especially suitable for compact ship decks.
Flexible Telescoping, Strong Adaptability: The telescopic arm function allows flexible adjustment of arm length based on the cargo position. Whether it's near the hull or deep inside the deck, it can handle it easily, significantly improving loading and unloading flexibility and efficiency.
Hydraulically driven, stable, and reliable: Telescopic knuckle boom cranes typically use a complete hydraulic drive system, offering smooth operation, rapid response, and adaptability to the complex, variable environments at sea. The hydraulic system possesses excellent anti-interference and anti-wear performance.
Standard load capacities and boom lengths of telescopic deck cranes
When selecting the appropriate telescopic foldable crane based on actual work requirements, the key considerations are the cargo weight to be lifted and the operating radius.
Light-duty operations (0.5-1 ton): Suitable for handling small items such as food supplies and spare parts. For example, a 0.5-ton fully telescopic jib crane with a 7-meter boom can lift 2 tons of cargo within a 2-meter radius, offering very high cost-effectiveness.
Medium-duty operations (3-10 tons): Suitable for conventional loading and unloading on general cargo ships. The 3-ton 12-meter full-jib crane is a common choice in the marine industry, effectively balancing load capacity and boom reach. The 5.6-ton 16.35-meter semi-jib crane is suitable for engineering vessels such as pile drivers and dredging ships.
Heavy-duty operations (10-30 tons): Suitable for scenarios requiring the lifting of large equipment or heavy objects. The 1.5-ton 18.1-meter semi-jib crane can handle loads up to 10 tons, while the 30-ton 38-meter jib crane can easily meet the lifting demands for 30-ton heavy objects.
Key configurations and certifications
The configuration and certification of marine cranes are directly related to operational safety and market access. The core configuration should be designed with safety and convenience in mind for marine operations, and certification should align with international marine standards.
360° Full Rotation: Standard 360° full rotation function allows the marine crane to rotate freely on the deck, making operations more flexible. Wireless
Remote Control + Cabin Dual Operation Mode: The wireless remote control enables long-distance operation, making it ideal for specific scenarios and simplifying and making it more convenient to work. The cabin is equipped with a precise control panel for micro-motion control, ensuring accurate cargo positioning.
Class Society Certification: The equipment fully complies with the certification requirements of major international class societies, guaranteeing safety and quality. For example, our YFM-produced deck cranes meet the certification requirements of international class societies, including ABS, CCS, and BV.
Material and Anti-Corrosion: The marine environment is harsh, and the equipment should be made of high-strength steel. The body surface is treated with a multi-layer anti-corrosion coating to resist salt-spray erosion and seawater corrosion effectively.
