What the specifications mean
The documented rear radius does not contain the whole working sweep. Include the chosen arm, bucket and front linkage when checking a narrow work position.
A reduced-rear-envelope crawler candidate for sites where the machine must work close to boundaries.
Alternatives worth comparing

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.
Used PC138USLC-11 inspection priorities
- Inspect rear-body contact points and the boom/arm assembly; verify the specified arm and shoes rather than assuming all USLC configurations match.
- 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 access work, relocation frequency and attachment readiness with a conventional crawler in the same job, rather than valuing compactness by itself.
- 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.
Excavator buckets and couplers
Verify pin or coupler geometry, attachment weight, linkage.
Open attachment researchHydraulic breakers and processors
Verify carrier class, flow, pressure, return and case drain.
