PRODUCTS & CASES

The multi-petal electric hydraulic grab bucket is a high-performance crane attachment specially designed for efficient handling of irregular, heavy, and bulk materials. It is widely used with overhead cranes, gantry cranes, portal cranes, and other lifting equipment for loading, unloading, sorting, and transferring operations.

The grab bucket features a multi-petal structure, typically consisting of six to eight symmetrical grab shells arranged around a central axis. Each grab shell is driven by a hydraulic cylinder through a connecting rod mechanism, enabling synchronized opening and closing movements. This design ensures strong gripping force, stable operation, and high material handling efficiency.

During operation, the hydraulic system controls the grab petals to open above the material, then close tightly to capture and lift the load. The wear-resistant inner surfaces of the grab shells provide excellent durability and are suitable for long-term heavy-duty operation. A lifting hook is installed at the top of the grab bucket, allowing quick connection and easy installation with different crane systems.

With its high adaptability, strong gripping capability, and reliable hydraulic control, the multi-petal electric hydraulic grab bucket is an ideal solution for handling scrap steel, ore, waste materials, rocks, and other irregular bulk materials in demanding industrial environments.

The multi-petal electric hydraulic grab bucket is mainly used for heavy-duty bulk material handling where high grabbing efficiency and strong adaptability are required.

Steel Industry

Used in scrap steel recycling plants and steel mills for grabbing, sorting, loading, and transferring scrap metal. Its powerful gripping capability improves handling efficiency and reduces manual labor requirements.

Ports and Terminals

Suitable for loading and unloading bulk materials such as coal, ore, sand, gravel, and other cargo. The grab bucket improves port handling speed and supports efficient logistics operations.

Construction Sites

Used for handling construction materials including sand, gravel, concrete blocks, and demolition waste, helping improve construction efficiency and maintain cleaner working areas.

Waste Treatment and Recycling

Applied in garbage treatment plants and recycling centers for grabbing and transporting solid waste, supporting efficient waste sorting and resource recovery.

Vehicle Recycling Yards

Used for handling large vehicle components and scrap materials during automobile dismantling operations.

Mines and Quarries

Suitable for loading and unloading ore, slag, waste rock, and irregular stones after blasting, providing reliable material handling solutions in mining environments.

Strong Gripping Capability

The multi-petal structure provides powerful and stable gripping force, making it suitable for irregular, large-size, and heavy bulk materials.

High Adaptability

The grab bucket can be installed on various lifting equipment, including:

• Overhead cranes

• Gantry cranes

• Portal cranes

• Other specialized lifting systems

It can be customized according to different material handling requirements.

High Operating Efficiency

The hydraulic drive system enables fast opening and closing movements, improving loading and unloading efficiency while reducing auxiliary operation time.

Low Material Resistance

The optimized grab shell structure reduces resistance when penetrating bulk materials, allowing smoother grabbing and better operation performance.

High Full Grab Rate

The optimized petal design effectively prevents material leakage during lifting, improving grabbing capacity and reducing material loss.

Excellent Wear Resistance

High-strength steel and wear-resistant materials are used for key components. Overlay welding technology further improves wear resistance and extends service life.

Flexible Hydraulic Control

The hydraulic system allows precise control of:

• Opening and closing speed

• Grab opening size

• Clamping force

This enables stable handling of different types of materials.

Easy Installation and Maintenance

The simple and modular structure makes installation, replacement, and maintenance convenient, reducing equipment downtime and operating costs.
