Cat 323 expert review

Reviewed by Zafer R. on September 29, 2025

Overview

The 2020 Cat 323D3 is a 22.8-ton medium excavator powered by a 144 hp Cat C7.1 engine. Designed for high-production applications, it offers robust performance in tasks such as earthmoving, trenching, and material handling. With an operating weight of 22,600 kg and a 1.2 m³ severe-duty bucket, the 323D3 delivers efficient digging and loading capabilities.

Pros The larger 1.2 m³ bucket increases material moved per cycle, improving overall job site efficiency. The eight-roller undercarriage and reinforced structures provide stability and longevity in demanding conditions.

Cons Lacks some of the advanced telematics and automation features found in newer models. While functional, the cab may not offer the same level of comfort and noise reduction as higher-tier excavators.

What's new

The 2020 model introduced several enhancements aimed at improving performance and operator experience. The excavator features a high-efficiency hydraulic system with tandem pumps delivering a maximum flow of 429 L/min, providing improved digging and lifting capabilities.

The machine's fuel system includes a two-stage filtration system with an anti-rust fuel tank, ensuring reliable performance and reduced maintenance needs.

Additionally, the 323D3 comes equipped with a heavy-duty, eight-roller undercarriage and reinforced structures, enhancing durability and stability during operation.

Efficiency and performance

In day-to-day operations, the Cat 323D3 demonstrates robust performance. Its digging depth reaches up to 6.3 meters, and the maximum reach at ground level is 9.47 meters, making it suitable for a variety of tasks.

The machine's fuel efficiency stands out, with operators reporting substantial savings over time. However, attention should be given to the cab comfort, as it may not match the standards of newer models.

Routine maintenance is facilitated by the machine's design, featuring easy access to service points, which helps minimize downtime and maintain consistent performance.

In-cabin and interior

The operator station of the 323D3 is designed with functionality in mind. The cab includes a high-resolution 203 mm (8") LCD touchscreen monitor, mechanically adjustable seat with headrest, and automatic bi-level air conditioner.

While the cab provides essential features for operation, it may lack some of the advanced comfort and noise reduction technologies found in newer models.

Safety features

Safety is a key consideration in the design of the 323D3. The machine is equipped with a fully enclosed ROPS and FOPS cab, protecting operators from rollovers and falling objects. The cab's design enhances visibility, reducing blind spots and contributing to safer operation.

The machine's maintenance-friendly design minimizes the risk of accidents during routine checks, and the inclusion of a backup alarm and interlock system further enhances operator safety.

In comparison

Compared to previous models, the 2020 323D3 offers improved hydraulic performance and operator functionality. When compared to competitors like the Komatsu PC210 LC, some users have noted that the 323D3's fuel efficiency and durability provide a competitive edge in terms of performance and operator satisfaction.

Verdict

The 2020 Cat 323D3 Medium Excavator earns a solid 5-star rating for its reliability, fuel efficiency, and operator-focused design. While attention to cab comfort and advanced technology features is necessary, the machine's overall performance and cost-effectiveness make it a valuable asset for various applications.
