The Cat 323 is a mid-size excavator rental for contractors who need more digging power, reach,
and production capacity than a compact excavator can provide. With 172 HP and an operating weight of 54,900 lbs, the Cat 323 is a strong fit for commercial sitework, utility trenching,
drainage, roadwork, truck loading, demolition support, and general earthmoving.

This machine is best used when the job requires steady excavation production, but does not require moving into a larger excavator class. It gives crews the size, stability, and working range needed for serious digging while staying versatile enough for multiple phases of site development.

About the Cat 323

The Cat 323 gives contractors a productive excavator option for jobs where compact equipment is too small, but larger excavators may be more machine than the project needs. It is large enough to support heavier excavation, trenching, loading, and drainage work, while still remaining practical for commercial sites, roadwork, utility corridors, and civil projects.

This machine works well as a primary excavator on mid-size excavation jobs or as a support machine on larger sites. Crews can use it to dig trenches, load trucks, shape ditches, move spoil, support stormwater installation, clean up demolition material, and handle general site development tasks.

The Cat 323 is not the smallest machine in the excavator lineup, and that is the point. Its value is in giving contractors better reach, stability, and digging performance when a compact excavator would slow production or limit what the crew can accomplish in a day.

Best Uses for the Cat 323

  • Commercial site excavation
  • Utility trenching
  • Storm drainage installation
  • Roadwork and civil construction
  • Subdivision development
  • Foundation excavation
  • Truck loading
  • Demolition cleanup
  • Ditching and slope shaping
  • General earthmoving
  • Industrial site prep
  • Backfill and grading support

Why Rent This Excavator?

Renting the Cat 323 helps contractors solve short-term production needs without adding another mid-size excavator to the fleet permanently. It is useful when a project needs more digging capacity than smaller machines can provide, when owned equipment is already committed, or when downtime needs to be covered quickly.

The Cat 323 can also help prevent under-sizing. On jobs where excavation, loading, and drainage work are tied to schedule performance, using a smaller machine may save on rental cost upfront but slow the project in the field. The Cat 323 gives crews a stronger production option for work that needs more reach, weight, and hydraulic performance.
