The clamshell grab, named for its opening and closing action that resembles the shell of a clam, is the most widely used type of grab. It is primarily used for loading and unloading bulk materials such as coal, ore, sand, grain, and garbage.
Lightweight grabs: Used for low-density materials such as grain and fertilizer. They feature thin plates and a light weight.
Medium-duty grabs: Used for common bulk cargoes such as coal and sand.
Heavy-duty grabs: Used for high-density, abrasive materials such as ore and scrap steel. Made of high-strength, wear-resistant steel plates (such as Hardox) and equipped with ribs and threaded sleeves.
