An excavating grab, also known as a clamshell grab, is a type of excavator attachment that is designed to scoop and grab loose or compact materials, such as sand, gravel, rocks, or debris. It consists of two hinged buckets, called clamshells, which open and close to grab and release the materials.
Excavating grabs are commonly used in construction, demolition, and mining operations, as well as in marine applications, such as dredging and marine construction. They can be attached to various types of excavators, such as hydraulic excavators, backhoes, and cranes, depending on the application and the size of the grab.
Excavating grabs come in various sizes and designs to suit different applications, and they may have additional features, such as teeth or replaceable cutting edges, to improve their performance and durability. They can also be operated manually or hydraulically, with hydraulic grabs offering greater control and efficiency.
