Overhead Crane with Clamshell Bucket and Grab Bucket
Overhead crane with clamshell bucket and grab bucket can grab bulk cargo and has a lifting capacity of 5 to 20 tons, it is ideal for heavy-duty working environments.
Introduction to Overhead Cranes with Clamshell and Grab Buckets
Overhead cranes equipped with clamshell and grab buckets are designed for handling bulk materials. These specialized cranes are commonly used in industrial settings such as power plants, docks, workshops, and storage facilities. The unique combination of clamshell or grab buckets with double girder configurations enhances their lifting capacity and operational efficiency, making them ideal for heavy-duty tasks.
Key Components and Features
Double Girder Design
Overhead Crane with Clamshell Bucket and Grab Bucket often utilize a double girder configuration. This structure provides:
- Enhanced Load Capacity: With lifting capacities ranging from 5 to 20 tons.
- Wider Spans: Spans of up to 34.5 meters ensure coverage for large working areas.
- Structural Integrity: The box-type girder design minimizes deflection, ensuring operational safety and stability.
Grab and Clamshell Buckets
- Clamshell Buckets: Suitable for fine materials like sand, gravel, and grain. They feature two hinged halves that scoop materials effectively.
- Grab Buckets: Used for larger or irregularly shaped items. They come in various designs, such as multi-rope or hydraulic grabs, to accommodate different materials.
Mechanisms
- Hoisting Mechanism:
- Incorporates durable steel wire ropes, high-capacity motors, and precision braking systems.
- Ensures smooth and reliable operation.
- Traveling Mechanism:
- Comprises independent drives for both trolleys and bridge frames.
- Features safety measures like anti-collision systems and limit switches.
Safety and Control Features
- Cab Controls: Provide operators with precise handling capabilities, ensuring safe and efficient operations.
- Ground Control: A more flexible option for smaller setups.
- Safety Protections:
- Anti-collision devices, overload limiters, and sound/light alarms enhance safety.
Applications of Overhead Cranes with Grab Buckets
These cranes are versatile and widely used in sectors requiring bulk material handling. Here are their main applications:
Power Plants
Clamshell and grab buckets are used to handle coal and biomass materials. Their efficiency ensures smooth material transport and reduced downtime.
Ports and Docks
In ports, these cranes play a crucial role in unloading ships carrying raw materials like iron ore, sand, and grain.
Workshops and Factories
Used for processing materials such as scrap metals or construction aggregates, overhead cranes ensure precise material placement.
Warehouses
Grab buckets help in moving bulk goods, increasing operational efficiency in large storage facilities.
