The excavator is a heavy construction machine used for digging, lifting, and moving materials. It typically consists of a boom, dipper, and bucket, mounted on a rotating platform called a house. Excavators are commonly used in construction, mining, and demolition projects to perform tasks such as trenching, grading, and site preparation. Excavators come in various sizes, from small mini-excavators for tight spaces to large models for heavy-duty work. They can be equipped with different attachments, such as buckets, hydraulic hammers, and thumbs, allowing them to perform a wide range of functions. Their versatility makes them essential in many industries.
