Description

The CAT 320 Excavator is a robust and adaptable machine designed for construction and mining applications. It features advanced technology and capabilities suited for a variety of tasks, including excavation, grading, demolition, and material handling.

The CAT 320 is powered by a CAT C4.4 ACERT engine, delivering a maximum net power output of 74 horsepower and an operating weight exceeding 33,000 pounds. This power-to-weight ratio enables the excavator to manage substantial loads and execute high-demand operations efficiently.

The excavator offers notable digging performance, with a maximum digging depth exceeding 20 feet and a maximum digging reach surpassing 32 feet. These specifications facilitate rapid and effective excavation of large volumes of earth. Additionally, the CAT 320 supports various attachments, including buckets and hammers, expanding its versatility for diverse excavation and grading tasks.

CASE CX320 Excavator Features At a Glance

The CAT 320 Excavator offers several optional features to enhance operational safety and efficiency:

  • Remote Control: The optional Command remote control system allows operation from outside the cab, reducing the risk of exposure to potential hazards.
  • People Detection: The optional Detect-People Detection system provides visual and auditory alerts to assist the operator in avoiding personnel on the job site.
  • Vehicle Health Management: An integrated vehicle health management system, available as an option, provides the operator with service alerts and information on necessary parts, improving machine uptime.
  • Global Navigation Satellite System (GNSS): An optional single-antenna GNSS system offers visual and auditory guidance for precise grading operations.
  • Auxiliary Relay: The optional auxiliary relay enables remote activation and deactivation of CB radios, beacon lights, and other attachments without requiring the operator to leave the joystick controls.
  • Inspection Lighting: Optional inspection lighting improves visibility for service tasks, enhancing safety and accessibility.
  • Swing Alarm: An optional swing alarm increases job site safety by alerting surrounding personnel of the excavator’s swing movements.

High Performance

The CAT 320 Excavator is equipped with a C7.1 twin-turbo engine that delivers consistent power to the hydraulic pumps, ensuring optimal production levels. The electrohydraulic system provides rapid and precise response to operational demands.

The excavator features three selectable power modes:

  • Power Mode: Provides continuous maximum engine and hydraulic power.
  • Smart Mode: Automatically adjusts engine and hydraulic power based on real-time digging conditions, delivering full power when required and reducing output during lower demand to enhance fuel efficiency.
  • Eco Mode: Lowers and maintains engine speed to minimize fuel consumption.
