INTRODUCTION
A Grab Ship Loader Crane is a specialized bulk-material loading unit engineered to transfer dry bulk commodities—such as coal, iron ore, clinker, fertilizers, and grain—from quay-side conveyors or hoppers directly into the holds of cargo vessels. Utilizing a heavy-duty mechanical or electro-hydraulic grab bucket suspended from a luffing or trolley-mounted boom, it delivers continuous, high-capacity loading for bulk carrier ships ranging from Barges up to Capesize vessels.
APPLICATION SCENARIO
Dry Bulk Cargo Ports: Loading large bulk vessels (Panamax/Capesize) with iron ore, coal, bauxite, and mineral concentrates.
Grain & Agricultural Terminals: Transporting wheat, corn, soybeans, and fertilizer granules from silos to ship holds.
Power Plants & Mining Wharves: Direct export/transfer of coal or crushed s
ADVANTAGES
High Loading Rates: Capable of handling massive volumes per hour (typically 500 to 5,000+ tons/hr), drastically cutting vessel berth time and demurrage costs.
Heavy-Duty & Continuous Operation: Built with robust steel structures and heavy-duty winch drives designed for harsh marine environments and non-stop 24/7 terminal operations.
-
Environmental Control: Integrated with dust suppression, telescopic chutes, and sealed grab designs to minimize dust pollution and material spillage during loading.
