Overview
A powerful series marine grab crane is a heavy-duty, full-rotation, hydraulically driven lifting equipment designed and manufactured for efficient bulk cargo loading and unloading operations of various types of ships in water environments such as sea, ports, and anchorages. It integrates advanced mechanical structure, precise hydraulic control and intelligent operating system, and can stably and reliably grab, lift, rotate, luff and release various types of bulk materials (such as coal, ore, sand and gravel, grain, fertilizer, scrap steel, etc.). It is an indispensable core equipment for bulk carriers, dredgers, engineering operation ships, barges, power plant feeder ships, etc.
Core structure and features
Heavy-duty structure: Made of high-strength steel, optimized boom design (optional fixed or luffing), solid turntable and base.
Powerful hydraulic system: Large flow pump station, load-sensitive proportional control, smooth and precise movement, and sufficient power.
Intelligent control system: PLC control, integrated safety monitoring and diagnosis; humanized operation room, wide field of view, convenient operation.
High-performance grab bucket: wear-resistant design (wear-resistant material surfacing on the cutting edge), optimized bucket shape to improve filling rate, quick connection.
Applications
Bulk carrier self-loading and unloading: loading and unloading of bulk cargo such as coal, ore, grain, etc.
Marine transshipment operation: bulk cargo transfer between large ships and small barges.
Dredger matching: grab and transfer dredged materials (sand, gravel, etc.).
Power plant/steel plant feeder ship: transport coal and ore to power plant docks or steel plant raw material docks.
Engineering ship operation: such as stone grabbing and dropping in riprap and immersed tube operations.
Port terminal auxiliary loading and unloading: as a supplement to fixed shore cranes or operations at specific berths.
Scrap recovery ship: grab and transfer scrap steel and solid waste on the water or shore.
