Excavators are used for underground utility construction like trenching. For trenching, the operator fills the bucket and dumps to the side above grade. It is used for digging and dumping into a dump truck or a pile. Excavators can accommodate numerous attachments such as pinches for lifting logs or pipes, a jacket hammer for busting up concrete or compacted soil, or a magnet for metal materials moving. Excavator attachments are similar to backhoe attachments and are run by hydraulics. Small excavators can be used for small shallow holes and big excavators for big deep holes.
