Our grab cranes are designed for efficient handling of bulk materials like coal, ore, sand, grain, and waste. Equipped with durable mechanical, electric or hydraulic grab buckets, they ensure smooth and reliable movement of heavy bulk materials in steel manufacturing, mining, ports, warehouses, and recycling facilities.
Overhead grab cranes operate on elevated runways and are typically used indoors or in covered workspaces. They consist of a bridge, trolley, hoist, and grab mechanism, and can operate in tight spaces without requiring additional floor area.
If you are working on small to light-duty bulk material handling operations indoors, a single girder grab bucket overhead crane is a cost-effective solution. With capacities from 2 to 10 tons, the single girder bridge crane design is ideal for smaller warehouses or workshops.
If you require heavy duty handling of bulk materials indoors, a double girder grab overhead crane with capacities from 5 tons to 20 tons is an ideal choice. This double girder overhead crane can lift heavier loads, span greater distances, and provide superior stability, offering more versatility for large-scale bulk material handling.
In addition to overhead crane with grab, gantry type cranes offer an alternative for outdoor or semi-outdoor operations where building a crane runway is impractical.
The single girder grab gantry crane is designed for lighter lifting requirements outdoors, typically up to 10 tons. This single girder gantry crane is ideal for open storage yards handling coal or sand, or small-scale construction sites moving loose materials.
The double girder gantry grab crane machine is suitable for outdoor handling of bulk loads up to 20 tons. This type of double girder gantry crane can be used in ports for loading and unloading cargo like ore and gravel, or outdoor industrial facilities requiring heavy bulk material handling.

In steel manufacturing plants, grabber cranes are vital for moving scrap metal, slag, and other heavy materials.
Common Uses:
Garbage grab cranes are used in waste management facilities for efficient handling and processing of large waste materials. They can quickly sort and move waste to recycling or disposal areas.
Common Uses:
Grabbing cranes are used in cement plants and construction material facilities for handling loose materials such as cement, sand and gravel.
Common Uses:
Grab bucket cranes play a vital role in coal-fired power plants and waste-to-energy facilities, handling various materials such as coal and biomass.
Common Uses:
Grab bucket cranes are commonly used in mining operations, handling heavy ores, slag, and waste materials.
Common Uses:
Grabs are essential lifting attachments for overhead and gantry cranes, specifically designed for handling bulk materials efficiently. There are three main types of grabs: mechanical grabs, electric grabs, and hydraulic grabs.
Mechanical crane grab buckets do not come with their own opening and closing structure. Instead, their opening and closing are controlled by a cable drum located on the crane’s trolley. They are simple, cost-effective, and particularly suitable for handling loose and bulk materials.
Applications:
Electric grabs are equipped with their own opening and closing mechanism, typically powered by an electric hoist or winch system attached to the grab itself. Compared to a mechanical grab, electric grab is more efficient and capable of handling heavier loads.
Applications:
Hydraulic grab for crane features an opening and closing structure powered by hydraulic cylinders. These grab buckets utilize multiple jaw plates that open and close to ensure efficient and precise material handling. They are highly automated, powerful, and suitable for heavy-duty operations.
Applications:
This guide will walk you through the essential considerations when buying an overhead or gantry crane with grab bucket to help you make an informed decision.
Begin by analyzing the material characteristics to determine the most suitable crane and grab attachment:
Each grab type has unique advantages tailored to specific applications:
The crane’s specifications must align with your operational requirements:
The crane’s operational environment significantly impacts its design and functionality:
Control systems influence the crane’s safety, efficiency, and ease of operation:
Custom features can optimize the crane for your specific applications, such as:
When considering purchasing a grab bucket crane, understanding the factors influencing its price is crucial. Here we will explore the elements that impact the grab crane price and provide insights to help you make an informed decision.
Crane CapacityThe greater the crane’s load capacity, the more expensive it is likely to be. For example, our 10 ton double girder grab bridge crane with a span of 10.5-31.5 meters may cost between $27,000 – $59,000 or more, while a larger capacity such as 20 ton with the same span range costs between $61,000 – $93,000 or more.
Grab TypeThe type of grab bucket you choose has a significant impact on price. For example, mechanical grab is the most cost-effective option, electric grab in crane is slightly higher in price due to integrated electrical components and precise control features, and hydraulic grab used in crane is more expensive because it uses advanced hydraulic systems for heavy-duty lifting applications.
Crane Type and ConfigurationCrane with grab bucket comes in various types and configurations, such as single girder and double girder. Double girder cranes, for example, offer enhanced stability and safety, but are more expensive than single girder options with the same specifications.
Span LengthA longer span requires additional engineering, stronger materials, and enhanced design features, which, in turn, drive up the price. The span range of 10.5-31.5 meters is commonly seen in double girder cranes. The wider the span, the higher the bridge crane price.
Understand Your RequirementsDetermine the lifting capacity, operating environment, crane type, and usage frequency. Clear needs ensure you avoid overspending on unnecessary features.

Understanding the mechanisms and operations of grab cranes is key for improving their efficiency, ensuring safety, and extending their lifespan.
To fully understand how grab cranes work, it is essential to understand their core components:
The grab bucket is the primary component that performs the lifting action. It consists of two or more clamshell-like segments that open to collect bulk material and close to securely lift and transport the materials.
The hoist system allows the crane to lift heavy loads vertically. It uses a combination of cables, pulleys, and motorized mechanisms to raise and lower the grab bucket.
Many grab cranes use hydraulic systems to ensure smooth and efficient movements of the grab bucket. The hydraulic system powers the opening and closing of the grab mechanism and other crane movements.
These cranes operate using advanced control systems. Operators can control movements with precision, using either manual or automated systems, depending on the crane’s design.
The crane’s frame, column, or rail system provides the necessary stability and movement pathways. Grabber cranes can be mobile or mounted on rails, depending on the application.
These cranes are powered by electric engines, which provide the necessary power for movement, hoisting, and lifting actions.
Grabbing cranes operate by integrating their hoist system, grab mechanism, and control system. The process involves multiple sequential steps:
The crane must first be moved into position. This can involve: grab rail crane movement to align the equipment over the material pile, or mobile gantry cranes moving across the ground to get into the ideal position.
The operator uses the control system to open the grab bucket, positioning it over the desired material.
The grab mechanism is closed by engaging the hydraulic or electric system. The mechanism can vary in its movement style, depending on whether the system uses hydraulic pressure or electric activation.
Once the grab bucket is securely closed and the load is collected, the hoist system lifts the bucket and moves it to the desired location.
Using either a rail-mounted system or a mobile path, the crane moves horizontally to transport the load to its destination.
At the destination, the operator uses the control system to open the grab bucket and release the material into its designated drop area.
