excavator
Let an agent explain excavators, relay types, mechanisms and uses from construction equipment sources, describe the named types and flag the brand instance, route digging and site safety, and distinguish excavators from backhoe loaders, bulldozers, cranes and trenchers.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain excavators, relay types, mechanisms and uses from construction equipment sources, describe the named types and flag the brand instance, route digging and site safety, and distinguish excavators from backhoe loaders, bulldozers, cranes and trenchers.
A heavy construction machine that digs and moves earth and material using a boom, dipper arm and bucket, usually mounted on tracks or wheels with a rotating cab, with types the registry aliases name such as compact or mini excavators, amphibious excavators for wetlands, road-rail excavators that work on rail lines, the walking dragline, a very large excavator used in mining, and excavation barges for dredging, along with brand models such as the Bobcat 328; excavators are used in construction, mining and demolition. They are powerful and dangerous machines, and operation needs training, exclusion zones for bystanders and checks for buried services before digging.
What it is for: Digging and moving earth and material.
It can be explain types and mechanisms; relay uses; describe named types; route digging and site safety.
Distinguishing features
Boom, arm and bucket
Rotating cab
Tracked or wheeled
Many specialised types
What it looks like
A tracked or wheeled machine with a rotating cab, boom, arm and bucket.
Physical character
key parts: boom, dipper arm, bucket, rotating house list
draglines: among the largest land machines note - mining
registry parents: earthmoving equipment, mechanical device note
How it is recognised
Digging machine with boom, arm and bucket
Bobcat 328, compact excavator, walking dragline, amphibious excavator, road-rail excavator, excavation barge
Backhoe loaders combine a loader and backhoe; bulldozers push with a blade; cranes lift; trenchers cut narrow trenches
