Ship Unloader Crane

High-Efficiency Bulk Material Unloading Solutions

A Ship Unloader Crane is a specialized port crane designed for the safe, fast, and efficient unloading of bulk materials from vessels to shore-based handling systems. It plays a critical role in reducing vessel turnaround time and improving terminal productivity.

Ship unloader cranes are widely used in ports, shipyards, cement terminals, power plants, and industrial bulk handling facilities.

Typical Materials Handled

• Cement

• Coal

• Grain & cereals

• Fertilizer

• Clinker

• Iron ore

• Aggregate & minerals

Working Principle

The ship unloader crane operates by lifting bulk material from the ship’s cargo hold using a grab bucket or integrated unloading device. The material is then transferred to:

• Hoppers

• Conveyor belts

• Screw conveyors

• Pneumatic conveying systems

The crane ensures controlled material flow, minimizing spillage, dust emission, and cargo loss.
