Grab buckets are specialized tools for cranes to handle dry bulk cargo. They consist of two or more hinged jaw plates that close to form a container space. During loading, the jaws close into the material pile, capturing the cargo. During unloading, the jaws open while suspended above the pile, allowing the cargo to fall onto the pile. The opening and closing of the jaws are typically controlled by the crane's lifting mechanism using steel cables. Grab bucket operations require minimal physical labor, achieve high loading and unloading efficiency, and ensure safety, making them the primary tools for handling dry bulk cargo at ports.
