Improving Bulk Material Handling Efficiency with Mechanical Grab Bucket Technology

In modern port logistics and bulk material handling operations, efficiency and reliability are critical to maintaining smooth operations. WUXI OUCO INTERNATIONAL GROUP CO., LTD continues to support global port and offshore industries with advanced solutions such as the Mechanical Grab Bucket, designed to improve loading and unloading performance for bulk materials.

A Mechanical Grab Bucket is a heavy-duty material handling attachment commonly used with four-rope cranes. The system typically operates with two holding ropes and two closing ropes, enabling stable grabbing and efficient unloading of bulk materials.

This equipment is widely used for handling materials such as:

• Sand
• Gravel
• Coal
• Ore
• Grain
• Construction aggregates

The design ensures stable operation even in high-frequency loading environments such as ports, shipyards, and bulk storage terminals.

The Mechanical Grab Bucket manufactured by OUCO is built using high wear-resistant steel, ensuring durability in demanding industrial conditions. The unit is also equipped with sealed heavy-duty bearings, reducing maintenance needs and extending service life.

A typical configuration includes technical parameters such as:

• Bucket capacity: 6 m³
• Pulley diameter: 560 mm
• Wire rope diameter: 26 mm

These parameters enable the grab to handle large volumes of bulk material efficiently while maintaining structural stability.

Bulk materials vary greatly in density. For example:

• Coal is relatively light
• Iron ore is significantly heavier
• Sand and gravel vary in bulk density

To accommodate these differences, OUCO offers optional kick plates, which can reduce the bucket's effective capacity. This allows the grab to match the lifting capacity of the crane and optimize material handling performance without overloading equipment.

This feature makes the Mechanical Grab Bucket particularly suitable for ports and terminals handling multiple material types.

Efficient loading and unloading of ships carrying bulk materials.

Handling of ores, coal, and other mineral materials.

Transporting sand, limestone, and aggregates.

Handling grain and fertilizer in bulk storage facilities.
