The bridge-type grab ship unloader is suitable for unloading bulk cargo barges and sea-going vessels. It is the core equipment for bulk cargo terminal loading and unloading operations, primarily used for ship unloading of bulk commodities such as coal, ore, and grain. The bridge-type grab ship unloader handles materials through the traditional opening, closing, lifting, and lowering of the grab. The technology is mature and reliable, offering good maneuverability and low maintenance requirements. It possesses irreplaceable advantages over other unloading methods in terms of adaptability to materials and vessels, operating costs, and avoiding damage to the unloader caused by wave-induced vessel pitching.
Product Advantages
1. Full Cargo Type Adaptability
Compatible with all categories of bulk cargo, from lightweight grain to high-density iron ore
2. High-Efficiency Operation Capability
Theoretical productivity up to 3000 t/h
3. Anti-Sway System
Achieves precise positioning under Sea State 8 conditions
4. Automation
Semi-automatic and fully automatic operations available
5. Precise Algorithms
