Excavators are equipped with various working devices, such as buckets, hydraulic breakers, grapples, and hydraulic shears. By quickly changing these devices, they can perform multiple tasks, including digging, loading, crushing, grabbing, and cutting. For example, in mining operations, excavators equipped with hydraulic breakers can easily crush hard ores; in urban demolition sites, excavators using hydraulic shears can quickly cut reinforced concrete structures.
