10 Ton Flange Mounted Folding Marine Crane

10-Ton Flange-Mounted Folding Marine Crane

Marine deck lifting operations often face challenges regarding limited available space and the continuous corrosive effects of marine salt spray. Shipowners frequently struggle to balance equipment stowage dimensions with rated lifting performance when selecting models, making it difficult to finalize a suitable solution. This 10-ton flange-mounted folding marine crane—classified as a knuckle boom crane—is mounted via a fixed flange base, specifically designed to address these operational challenges. It features a lifting moment of 50 ton-meters, a rated load of 10 tons at a 4.2-meter outreach, a maximum working radius of 10.303 meters, a maximum lifting height of 12.3 meters, and 360° full-circle slewing capability. Its compact folded profile minimizes deck footprint, making it ideal for workboats, barges, and fishing vessels tasked with material replenishment and onboard spare parts handling; certification from classification societies such as CCS, ABS, and BV is available.

Different types of lifting equipment have distinct operational niches: while telescopic boom cranes excel in long-range, linear lifting tasks, marine knuckle boom cranes offer superior flexibility in confined spaces, serving as a complementary solution to telescopic boom cranes. In addition to marine cranes, we also supply grab machines and forestry cranes (log-handling grab machines), fulfilling orders for lifting and grabbing equipment tailored to various operational requirements.

Product Features

1. Flange-mounted base installation; hydraulically driven with a 360° full-slewing structure; the entire unit undergoes marine-grade anti-corrosion treatment, making it suitable for high-salinity marine environments.

2. Rated lifting moment of 50 ton-meters; rated lifting capacity of 10 tons at a 4.2-meter outreach; compact folded boom structure designed to fit within the limited installation areas of ship decks.

Usage Tips

1. Before operation, verify the tightness of the flange base mounting bolts. Perform lifting strictly in accordance with the load chart; overloading or exceeding the rated operating radius is prohibited.

2. During extended periods of inactivity, retract the boom to its folded position and protect exposed hydraulic lines and articulated joints to minimize corrosion and wear.

FAQ

Q1: How do the application scenarios for this model differ from those of a telescopic boom crane?

A1: This product is a knuckle boom crane; its articulated boom design is ideal for luffing operations in confined deck spaces, making it frequently used for ship-to-ship or ship-to-shore supply transfers. Telescopic boom cranes are better suited for long-reach lifting in open areas. Customers should select the appropriate model based on deck layout and required operating radius.

Q2: Is the daily maintenance workload excessive?

A2: The hydraulic piping is neatly arranged, and core hydraulic components meet marine standards. Routine maintenance primarily involves periodic hydraulic oil changes and inspections of seals and the slewing bearing; a complete set of maintenance procedures is provided with the equipment.

Q3: Can relevant classification society certificates be provided?

A3: Certifications from CCS, ABS, or BV can be arranged based on project requirements, with the necessary documentation delivered alongside the equipment.

Q4: What does the after-sales support cover?

A4: A warranty period applies to the entire unit. Replacement parts are provided for core components suffering non-human-induced damage within the warranty scope. Technical personnel can offer remote commissioning guidance, and on-site technical services can be arranged separately.

Q5: Besides marine knuckle boom cranes, do you supply other lifting equipment?

A5: We also offer ship telescopic boom cranes, grab cranes, and forestry cranes (log grapples), covering applications such as shipboard lifting, bulk material handling, and log handling; bulk procurement is supported.
