Clamshell buckets are versatile attachments designed for use with cranes and excavators, offering efficient solutions for loading, unloading, and handling various materials. This guide provides an in-depth look at the features, applications, and benefits of clamshell buckets.

Types of Clamshell Buckets

General Purpose Clamshell Buckets

These buckets are designed for all-purpose loading work and are suitable for a wide range of cranes and excavators. They are efficient at loading materials by forcing their shells into the material, unlike standard buckets which push the material outward[1].

Universal Grab Clamshell Buckets

These buckets, such as the TGO model, come with removable side plates. This feature allows the operator to grip large objects like trees securely with the plates removed and to handle loose materials when the plates are bolted on[1].

Light Material Clamshell Buckets

Designed for handling light materials, these buckets have a larger volume but a very low weight to maximize the excavator’s capacity. Examples include the TCB 420L – 800L models[1].

Heavy Duty Clamshell Buckets

These buckets are built for heavy-duty applications, such as moving stockpiles and handling abrasive materials. They often feature heavy-duty bearing rotators and high-abrasion resistant alloy steel on the leading edges[4].

Specialized Clamshell Buckets

• Superchip Buckets: Designed specifically for moving bulk wood chips, these buckets are lighter to maximize the excavator’s capacity[1].
• Round Hydraulic Clamshell Buckets: These can be equipped with extension arms and are used for digging and dredging activities[3].

Key Features

Mounting and Suspension

Clamshell buckets are typically mounted via a link-cardanic suspension, although some heavy-duty models may be suited to rigid mounting[1].

Materials and Construction

• High-Quality Steel: Many clamshell buckets are made from high-quality steel, such as HARDOX, to ensure extra strength and durability[1].
• Bolt-on Edges: Some models come with bolt-on edges for extra wear protection[4].

Hydraulic and Mechanical Components

• Pilot Operated Valves: Many models feature pilot operated check/overcentre valves for efficient operation[1].
• Greaseable Pins: Pins are often greaseable with protected grease nipples to ensure a long life[1].
• Bronze Bushes: Bronze bushes are used throughout to maximize the life of the bucket[1].

Rotation and Control

• 360 Degree Continuous Rotation: Some clamshell buckets come with heavy-duty bearing rotators allowing for 360 degrees of continuous rotation[4].
• Remote Control Operation: Certain models, like the Boscaro A-400DR and A-800DR, can be controlled via wireless remote control from the crane cab or by designated personnel[2].

Applications

Loading and Unloading

Clamshell buckets are highly efficient for loading and unloading various materials such as industrial wastes, grains, sands, rocks, and more. They can be used in conjunction with mobile and/or tower cranes[2][3].

Dredging and Digging

These buckets are also used for dredging and digging activities, especially in environments where precise material handling is required[3].

Port and Stevedoring Operations

Clamshell buckets are widely used in port industries for loading and unloading raw materials, coal, iron, and grain[4].

Benefits

Efficiency

• Clamshell buckets allow for efficient loading by clamping into the material, reducing the need for repeated scooping and pushing[1].
• They enable trucks to self-load with a crane, freeing up site machinery for other uses[1].

Safety

• Remote control operation models ensure that personnel do not need to be inside the operating area, enhancing safety[2].
• They can be used in confined or space-restricted areas without compromising safety[2].

Customization

• Many manufacturers offer customized sizes and designs to fit specific customer requirements[3][4].

Maintenance and Durability

High-Quality Materials

The use of high-quality steel and other durable materials ensures that clamshell buckets have a long lifespan[1].

Easy Maintenance

Features like greaseable pins and bronze bushes make maintenance easier and extend the life of the bucket[1].

Conclusion

Clamshell buckets are indispensable attachments for cranes and excavators, offering a range of benefits including efficiency, safety, and durability. By understanding the different types, features, and applications of these buckets, users can make informed decisions to enhance their operational capabilities. Whether for general purpose loading, specialized tasks, or heavy-duty applications, clamshell buckets are versatile tools that can significantly improve material handling operations.

Frequently Asked Questions (FAQs)

What are the key components and types of clamshell buckets used in crane operations?

Clamshell buckets are crucial attachments for cranes, and they consist of several key components. These include two hinged shells that can open and close, a linkage mechanism (which can be hydraulic or mechanical) to control the shells, and a cylinder (hydraulic or pneumatic) that operates the linkage. Additional components include teeth made of high-strength steel for gripping materials, a cutting edge for leveling and cutting, and lifting ears for attaching to the crane’s cables. There are several types of clamshell buckets, including mechanical, hydraulic, electro-hydraulic, and radio-controlled versions. Mechanical clamshell buckets are used for smaller-scale applications, hydraulic ones for larger-scale tasks requiring precise control, electro-hydraulic buckets for advanced control features, and radio-controlled buckets for remote operation in hazardous areas.

How do you prepare and operate a clamshell bucket crane safely and efficiently?

Preparing and operating a clamshell bucket crane involves several critical steps. First, ensure the crane is in good working condition by inspecting for any damages or faults and performing necessary maintenance. Position the crane on stable, level ground that can support the crane’s weight and the intended load. Attach the clamshell bucket securely to the crane’s hook using cables or chains, ensuring it can withstand the load’s weight. During operation, follow the manufacturer’s instructions for crane controls, lifting the load slowly and smoothly to maintain balance and prevent accidents. When transporting the load, navigate carefully around obstacles, and release the load by opening the clamshell bucket at the desired location.

What factors influence the selection of a clamshell bucket for specific material handling tasks?

The selection of a clamshell bucket depends on several factors, including the type and weight of the material to be handled, the size and capacity required, and the operating environment. The bucket size, typically measured in cubic meters, needs to be appropriate for the material volume. For example, lighter materials like grain or fertilizer might require lighter-duty buckets, while heavier materials such as rocks or hard soil necessitate heavy-duty buckets. The material’s specific gravity and the need for precise control or remote operation also influence the choice between mechanical, hydraulic, electro-hydraulic, or radio-controlled clamshell buckets.

What maintenance and insurance considerations are important for clamshell bucket cranes?

Maintaining a clamshell bucket crane is essential for its longevity and safe operation. Develop a maintenance plan based on the manufacturer’s recommendations, which includes regular inspections, lubrication through grease fittings, and replacement of worn-out parts such as pins and bushings. Ensure that all mechanical and hydraulic components are in good condition. Additionally, consider obtaining appropriate insurance coverage to protect against unforeseen events or damages. This includes coverage for the crane itself, as well as liability insurance to cover potential accidents or property damage.

What are the advantages of using clamshell bucket cranes in various industries?

Clamshell bucket cranes offer several advantages across different industries such as construction, maritime, and mining. They are versatile and can handle a wide range of materials, from small particles to large, heavy debris. These buckets are time-saving as they can carry large amounts of material in a single trip, reducing the number of trips and the need for additional labor and equipment. They are also cost-effective, as the ability to handle large volumes of material in one go saves on operational costs. Furthermore, clamshell bucket cranes provide precise control and excellent material retention, making them an essential tool for efficient and safe material handling operations.
