What the specifications mean

The published PC55MR-5 values remain attached to their stated configuration and rating basis.

PC55MR-5; 2900 mm boom and 1640 mm arm; rubber tracks; standard blade and digging bucket in brochure transport posture. Overall width covers the manufacturer standard envelope.

An individual machine must be verified by serial/PIN, installed equipment and actual measurements.

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.

Used PC55MR-5 inspection priorities

Inspect tracks, sprockets, rollers, idlers, final drives and travel response.
Measure boom, arm, bucket, swing-post and blade pin wear.
Operate the coupler and auxiliary circuits with the intended tool when practical.
Match the PC55MR-5 model plate, fitted equipment and serial/PIN to the cited generation and configuration.

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

Track wear, compact service access and attachment duty drive hourly cost.
Blade, coupler and auxiliary packages materially affect fit and value.
Trailer, tow vehicle and attachment mobilization belong in the cost model.
