What the specifications mean

The published 320 GC values remain attached to their stated configuration and rating basis.

Caterpillar 320 GC — Dimensions. Boom: Reach 5.7 m (18'8") Stick: Reach 2.9 m (9'6") Bucket: GD 1 m³ (1.31 yd³)

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 320 GC inspection priorities

Measure the complete undercarriage and check travel and final drives under load.
Cycle boom, arm, bucket and swing while checking cylinders, pins and slew movement.
Confirm coupler, auxiliary circuits and installed technology from the actual machine.
Match the 320 GC model plate, fitted attachment and undercarriage to the cited reference 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

Undercarriage, pins, cylinders, pumps and final drives need evidence-based reserves.
Attachment duty changes fuel, cooling and hydraulic wear.
Transport exposure changes with shoes, front, counterweight and guarding.

Relationships below identify relevant classes only unless a stronger evidence state is shown. They never assert exact used-attachment fitment.
