Excavator specs refer to the technical details and performance characteristics of an excavator, a heavy construction machine used for digging and earthmoving. Key specifications include the machine's operating weight, engine power, bucket capacity, and maximum digging depth. These specs help determine the excavator's suitability for specific tasks, such as trenching, grading, or demolition. Other important specs include the swing radius, which affects maneuverability, and the reach, which indicates how far the arm can extend. Additionally, features like hydraulic flow rate and attachment compatibility can enhance the excavator's versatility for various jobs, making it a valuable asset on construction sites.
