Excavators are commonly used mechanical equipment in the engineering field. They are powered by engines, and hydraulic systems drive working devices such as booms, dipper arms, and buckets.
They have crawler and wheeled travel modes. They can rotate 360 degrees and are flexible to operate. By replacing accessories such as breaker hammers and grabs, they can achieve a variety of operating functions, such as digging, crushing, and grabbing. They are widely used in construction, mining, municipal engineering, agricultural production, and other fields, with high operating efficiency and guaranteed safety performance.
