A grab bucket for a crane is a highly efficient tool that is used for a wide range of applications in industries such as construction, mining, and shipping. It is a type of crane attachment that is designed to pick up and move loose materials such as sand, gravel, debris, and waste. The grab bucket is operated by the crane’s hydraulic system and can be easily attached or detached from the crane arm.
Types of Crane Grab Buckets
Electro-hydraulic orange peel grab bucket:
Capacity: The standard grab bucket capacity range is 0.8m³ ~ 20m³, and its corresponding motor power range is 8.5 kw ~ 55 kw.
Handling loads: The orange peel grabs are typically used to handle block, granular, and irregular bulk materials, such as coke, pig iron, scrap steel, slag, garbage stones, etc.
Features: The orange peel grab could be directly connected with the crane hook with a simple and convenient connection, with the features of high grabbing efficiency and stable working performance.
Uses and applications: The orange peel grabs are widely used in docks, steel plants, and waste incineration plants
Electro-hydraulic clamshell crane bucket:
Capacity: The electro-hydraulic clamshell grab bucket volume is 0.8m³～26.0m³. The corresponding motor power range is 8.5 kw～55 kw.
Features: The crane grab buckets can be operated in a corrosive environment for a long time, the pins of each hinge point are treated with anti-corrosion effectiveness to ensure the reliability of the pins over a long period.
Loads handling: The electro-hydraulic grab is used to grab powder and granular bulk materials, typically fertilizer, grain, coal, coke, ore, sand, granular building materials, crushed stone, and other bulk materials, etc.
Uses and applications: The clamshell grabs can cooperate with various types of bulk material handling cranes such as tower cranes, ship cranes, and ship unloaders. They are suitable for bulk load handling in wharves, steel mills, power plants, ships waste incineration plants, etc.

Advantages of Grab Bucket for Cranes
Ability to handle large volumes of material quickly and efficiently. This makes it an ideal tool for tasks such as loading and unloading cargo ships, excavating and transporting materials in construction sites, and clearing debris from demolition sites. The grab bucket can also be used to sort and separate different types of materials, making it a versatile tool for a wide range of applications.
High precision and easy control. The grab bucket can be operated with great accuracy, allowing operators to pick up and move materials with ease. This makes it an ideal tool for tasks that require a high degree of precision, such as loading and unloading cargo ships or excavating materials in tight spaces.
High durability and reliability. It is typically made from high-quality materials such as steel or aluminium, which ensures its longevity and resistance to wear and tear. The grab bucket is also designed to withstand heavy loads and extreme conditions, making it ideal for use in harsh environments such as mines or offshore drilling platforms.
Choosing Grab Buckets
When selecting a grab bucket for a crane, it is important to consider factors such as the size and weight of the materials being handled, the type of crane being used, and the specific application for which it will be used. It is also important to choose a grab bucket that is compatible with the crane’s hydraulic system and that meets all relevant safety standards and regulations.
Capacity and Size—The capacity of the bucket will depend on the type and density of the material you will be handling. It is essential to choose a grab bucket that is large enough to handle your material efficiently without being too heavy or cumbersome.
Material Type–Different materials require different types of grab buckets. For instance, a rock grab bucket is designed to handle large rocks, while a waste grab bucket is designed to handle lighter materials such as garbage or sacramental.
Operating Environment– If you will be working in a hazardous or corrosive environment, you will need a grab bucket that is specifically designed to withstand these conditions. Similarly, if you will be working in a confined space, you will need a grab bucket that is compact enough to fit in the space.
Attachment Method–The attachment method is another important consideration when choosing a grab bucket. There are several attachment methods available, including quick couplers, pin-on attachments, and hydraulic couplers. The choice of attachment method will depend on your specific needs and the type of equipment you will be using.
