III. Supplementary Performance Features

In addition to the above core parameters, the Komatsu PC400-8 also possesses the following outstanding performance features:

Multi-mode Operation Selection: Allows switching between operation modes according to different working conditions, adapting to diverse construction needs.

High Reliability Design: Utilizes high-performance filter materials, extending oil and filter replacement intervals; equipped with an equipment management and monitoring system, effectively monitoring equipment status and reducing malfunctions; high-pressure series filter elements prevent hydraulic system contamination.

Safety Protection Configuration: A high-rigidity cab combined with seat belts protects the driver in rollover accidents; a hydraulic locking lever design prevents misoperation, and the engine can only be started when locked; a steel-protruding anti-slip plate significantly improves the anti-slip properties of the operating area.
