Introduction of bridge-grabbing crane

 

Overhead bridge cranes are installed on beams and columns in factories, workshops, and warehouses to facilitate material handling and are usually equipped with grabs. The grab of an overhead crane is used for gripping and handling bulk and lump materials.

 

Features:

Fabricated from premium-grade carbon steel (e.g., ASTM A36, ASTM A572, S355, Q235B, Q355B) for superior load-bearing capacity and structural integrity.

Advanced surface treatment for improved durability.

Wide span range to suit different facility layouts.

 

2 Types of grab buckets for bridge crane

 

According to the shape of the grab, it can be categorized into two main types clamshell grab cranes and multi-petal orange peel grab cranes.

Clamshell Grab Bridge Crane
01.

Clamshell grab bridge crane

The clamshell grab cranes are suitable for ports, freight yards, mines, and other places where bulk cargo, minerals, gravel, and other materials need to be loaded.

02.

Multi-petal grab crane (orange Peel Grab Crane)

For loading and unloading timber, steel scrap, or sorting materials, it is necessary to use a multi-petal grab crane. The bucket teeth of the crane usually use high-strength wear-resistant steel to improve the service time of the bridge-grabbing cranes.

Advantages of grab bridge crane

1

Overhead bridge cranes equipped with grabs significantly improve factory automation, streamlining the material handling process.

2

Fitted with large-volume grabs, these bridge cranes can move quantities of materials in a single operation, making them ideal for batch processing and large-scale handling tasks.

3

The high lifting capacity of the grab bridge cranes enables them to meet a wide range of material handling needs.

4

Compared to traditional manual or semi-automated handling methods, bridge grab cranes offer a higher degree of automation. This reduces the need for manual labor, lowers the risk of workplace accidents, and improves overall safety.

5

Equipped with advanced intelligent control systems, these cranes offer precise positioning, stable operation, and improved safety.

 

Wide applications of overhead grab crane

Bridge grab cranes are widely used in various industries for efficient and automated bulk material handling. Their versatility and high capacity make them ideal for demanding environments such as:

clamshell crane
mining industrial clamshell crane
waste grab crane
double girder crane with orange peel grab

1. Port terminals and logistics

At ports and stockyards, grab bridge cranes are essential for loading and unloading bulk materials such as coal, grain, and other loose cargo, optimizing port throughput.

 

2. Mining and metallurgy industry

In mining and metallurgical plants, clamshell grab cranes are used to handle raw materials like coal, iron ore powder, and bulk substances. While multi-jaw grab cranes are used to sort and move large-size recycled metal scraps.

 

3. Power and energy industry

In thermal power plants, grab overhead cranes are used to feed coal, coke, and other fuels into boilers, ensuring continuous and efficient power generation.

In biomass power plants, overhead bridge cranes with grab are used to distribute biomass fuels such as wood chips and sawdust to support clean energy production.

 

4. Construction and building industry

Grab cranes are used to handle construction materials such as cement, lime, and sand. By automating material transportation on-site, they help reduce labor costs, accelerate project timelines, and improve building efficiency.

 

5. Chemical plants

In chemical processing facilities, bridge grab cranes assist in transporting materials like fertilizers and powdered chemicals. Their handling capability minimizes material loss and supports a safer working environment.
