Product Description

high-performance hydraulic Heavy-duty articulated boom(IB)marine cranes

Heavy-duty articulated boom(IB)marine cranes are available in different capacities ranging from 8 to 400 tm. This kind cranes are custom built according to requested load,radius and sea state.

Specification

Applications

Construction and operation of offshore oil and gas platforms: Hoisting drilling equipment, pipelines, modular components, as well as daily material supply and equipment replacement for the platforms.
Heavy lifting in marine engineering: Participating in the offshore installation and positioning of subsea tunnel immersed tubes, cross-sea bridge components, and large marine structures.
Transfer of ships and heavy equipment: This involves transferring heavy machinery (such as excavators and cranes) between large engineering ships and semi-submersible ships or hoisting ship sections.
Deployment and recovery of deep-sea equipment: To support deep-sea resource development, underwater robots (ROVs), deep-sea drilling equipment, submarine cable laying machines, etc., are deployed.
Construction of offshore wind power projects: Hoisting significant components such as wind turbine towers, blades, and generator sets, as well as equipment replacement during later operation and maintenance.
Emergency rescue and salvage: Hoisting damaged equipment or extensive wreckage in shipwreck salvage and marine accident rescue, cooperating with marine rescue operations.
Heavy cargo handling in ports: Loading and unloading oversized cargo (such as pressure vessels and engineering modules) for special ships (such as ro-ro ships and general cargo ships).

Key Configurations

High-strength composite boom: This multi-section telescopic + folding structure is made of ultra-high-strength alloy steel, balancing rigidity and lightweight, and is suitable for large-tonnage loads.
High-power hydraulic system: This includes high-pressure oil pumps, multi-way directional valves, hydraulic motors, etc., providing strong and stable power output to drive the boom's telescoping, folding, and slewing.
Large-tonnage hoisting mechanism: Equipped with high-torque winches (including steel wire ropes/chains) and heavy-duty hooks, with a single hook lifting capacity of tens to hundreds of tons to meet heavy-load requirements.
Full-slewing support device: This device supports 360° continuous slewing, combined with precision bearings and drive gears to ensure the boom's flexible rotation and accurate positioning.
Anti-corrosion protection system: Key components such as the boom and body adopt anti-salt spray coatings, stainless steel materials, and sealing designs to resist erosion in marine environments.
Intelligent safety control system: Integrates torque limiters, overload protectors, height/amplitude limiters, and emergency braking devices, some of which include wind and wave compensation modules.
Multifunctional control terminal: This terminal supports manual cabin control and remote wireless control. It is equipped with a display screen that shows real-time parameters such as load and angle for precise operation.
Auxiliary hydraulic accessories: The truck can be equipped with hydraulic grabs, spreaders, etc., to adapt to different operation needs (such as cargo grabbing or equipment hoisting).

Core advantages

Super strong load capacity: Equipped with large-tonnage hoisting mechanisms and high-strength booms (mostly made of alloy steel), the single hook lifting capacity can reach tens to hundreds of tons, meeting the lifting needs of large-scale equipment and components.
Robust and durable structure: The rigid structure, combining folding arms and telescopic arms, has strong deformation resistance. Combined with anti-salt spray, anti-corrosion coatings, and sealing designs, it can withstand harsh marine environments such as high humidity and strong wind waves.
Flexible operating range: The boom can be significantly extended and retracted (up to tens of meters long) and flexibly folded. Combined with the 360° full-slewing function, it can cover large-radius and multi-angle operating areas, adapting to complex scenarios such as ships and platforms.
Precise power and control: Adopting a high-power hydraulic system to provide stable power output; supporting multi-level speed adjustment and manual/remote control operations, enabling smooth lifting and micro-motion positioning under heavy loads (such as offshore platform equipment installation).
Comprehensive safety system: Equipped with multiple devices for overload protection, torque limitation, height limitation, and emergency braking. Some models include wind and wave compensation functions to reduce operational risks under sudden working conditions.
Strong adaptability: It can integrate auxiliary equipment (such as hooks, grabs, spreaders) according to needs, and is widely used in heavy-duty scenarios such as marine engineering, oil and gas development, and heavy cargo transfer.
