What the specifications mean
The record labels the undercarriage width as extended and gives separate protective-structure information. Do not assume an unverified retracted or folded width/height.
A micro-excavator research option for very restricted access and small excavation tasks.
Alternatives worth comparing
These are research paths, not interchangeable configurations or a ranked winner.Takeuchi TB210R Mini Excavator
Extended-track width is not the narrow travel setting. Verify the manufacturer's required working configuration and the exact canopy/ROPS transport position.

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.
Used 300.9D inspection priorities
- Confirm undercarriage extension and protective-structure procedures; inspect compact linkage, travel systems and blade mounting.
- Record the exact serial/PIN, installed options and inspection limitations. These are purchase inspection priorities, not claims of a model-specific failure pattern.
Configuration-aware inspection: these checks are triggered by machine category, installed configuration and technology package. Brochure-listed technology must be physically present, active, licensed and calibrated on the used machine.
Hours, condition and ownership cost
Hours are context, not a condition grade. Duty cycle, idle time, maintenance evidence, wear-system measurements, structural repairs and installed technology should be evaluated together.
Cost drivers to model
- Compare hand-access constraints, transport and job duration with a larger compact machine that may need access preparation.
- Use the ownership calculator with quoted repairs, actual scheduled hours, utilization and transport costs; leave unknown assumptions visible.

Attachment considerations
Relationships below identify relevant classes only unless a stronger evidence state is shown. They never assert exact used-attachment fitment.
Compact excavator buckets and couplers
Verify pin or coupler geometry, tool weight, machine configuration.
Open attachment researchBreakers, augers and compactors
Verify flow, pressure, return, case drain, controls.
Open attachment researchBefore confirming fitment
- generation and machine configuration
- mounting interface, coupler or pin geometry
- hydraulic flow, pressure, return and case drain
- attachment weight and machine capacity limits
- electrical controls or required machine options
Model-reference transport profile
Transport reference
Reference measurements retain their configuration and verification status. Confirm the actual transport setup before booking.
Reference specifications can differ from the actual configured machine. Confirm dimensions and weight before booking transportation.
Confirm or replace before a transport request
- actual weight
- actual travel length, width and height
- attachments and removable work tools
- bucket, blade, carriage or boom position
- loading condition
