Excavators are powerful machines used primarily in construction and mining for digging and moving large amounts of earth. They consist of a boom, dipper, bucket, and a rotating platform, allowing them to perform a variety of tasks such as trenching, lifting, and demolition. Their versatility makes them essential for many projects, from building foundations to landscaping. These machines come in various sizes, from compact models suitable for small jobs to large excavators designed for heavy-duty work. With advancements in technology, modern excavators often feature hydraulic systems and can be equipped with attachments like buckets, breakers, and grapples to enhance their functionality.
