In maritime and offshore operations, equipment is challenged to balance "heavy-load lifting" and "flexible operation in complex environments". MAXTECH's Knuckle Boom Cranes, with their unique folding arm design, precise control performance, and wide scenario adaptability, have become core equipment in ship decks, offshore platforms, and offshore fields. Among them, the 20t15m and 30t5m semi-knuckle boom marine crane vividly demonstrate the technical advantages of this series through their outstanding performance in typical working conditions.
The core competitiveness of knuckle
Boom Cranes lies in their
multi-section folding arm structure:
- Heavy-load capacity: When the jib is extended, it can achieve high-strength lifting. The 30t5m offshore crane can easily lift 30 tons at a working radius of 5 meters, meeting heavy-load needs such as ship supply and large equipment transfer. The 20t15m model maintains a 20-ton lifting capacity at a 15-meter radius, suitable for long-distance precision placement scenarios.
- Flexible operation: In the folded state, the jib can be significantly retracted, reducing the equipment's footprint on the deck by 40% and saving valuable space on the ship. This "extend to lift, fold to store" feature makes it more practical than traditional straight-arm Deck Cranes in space-constrained shipboard environments.
- Deck Cranes (Shipboard): The 20t15m model often serves as the main shipboard equipment, undertaking tasks such as ship supply (Provision Cranes) and spare parts transfer (Service Cranes). Its compact size after folding does not affect the ship's center of gravity balance during navigation.
- Ship to Ship Transfer: The 30t5m model, with its short-radius heavy-load capacity, performs excellently in cargo transfer between ships, especially suitable for efficient lifting of containers and large machinery.
- Pipe Handling: For pipeline laying in offshore engineering, the marine crane can realize horizontal lifting and precise docking of long pipes through customized spreaders. The multi-angle folding capability of the jib adapts to the complex path of pipes between the deck and the seabed.
- Boat Handling: In the launching and recovery operations of lifeboats and workboats, the flexible controllability of the knuckle boom crane can reduce the collision risk caused by sea waves, ensuring the safety of personnel and equipment.
- Structure and Protection: The main arm is welded with high-strength low-alloy steel, and key parts undergo non-destructive testing. The surface is treated with multi-layer anti-corrosion (primer + epoxy intermediate coat + fluorocarbon topcoat), with salt spray resistance of more than 5,000 hours, perfectly adapting to the highly corrosive marine environment.
- Customization Capability: In addition to standard models such as 20t15m and 30t5m, configurations with different lifting moments from 130–30,000 kNm can be provided according to customer needs, supporting personalized customization of spreaders and control systems, such as explosion-proof control systems designed exclusively for offshore platforms.
- Operational Convenience: Equipped with dual operation modes of wireless remote control and cab, the operating handle integrates force feedback function, allowing operators to intuitively sense the load status. Combined with real-time load, angle, wind speed, and other data on the LCD screen, it further improves operational safety.
Whether it is heavy equipment supply on offshore platforms or cargo transfer between ships, MAXTECH knuckle boom cranes, with their core advantages of "heavy load without losing flexibility, compactness without losing power", redefine the performance standards of maritime lifting equipment. As a preferred solution for scenarios such as deck cranes, ship to ship cranes, they are helping global maritime customers achieve efficient and safe operations in complex environments.
