Excavators are versatile earthmoving machines with a rotating cabin, boom, stick, and bucket. Available in sizes from 2 tons to 90+ tons, excavators are essential for excavation, grading, material movement, and demolition work. Standard bucket capacities range from 0.5 to 5+ cubic yards depending on machine size. Excavators can be equipped with various attachments: grapples, magnets, hammers, and specialty buckets. Typical rental costs range from $150-$500 per day depending on size. Operator certification is recommended but not always required. Fuel consumption typically ranges from 3-15 gallons per hour depending on machine size and duty cycle. Excavators are tracked (better for soft soil) or wheeled (better for roads and hard surfaces). Maintenance includes regular service, bucket repair, and attachment maintenance.
