Customers today are demanding strong machine and jobsite performance that helps lower operating costs and increase productivity. Designed for construction, utility and road maintenance applications, the new Cat M320 wheeled excavator delivers enhanced ease of use, efficiency, stability and reduced operating costs.
The M320 cab is designed with controls that are easy to reach to help support operator comfort and capability. A high‑resolution touchscreen monitor provides an intuitive interface to help operators maintain consistent performance throughout the workday.
The M320 also incorporates a new auto axle lock feature that automatically activates when the travel pedal is in neutral and the machine speed is near zero. A two-way travel pedal supports machine movement. Compared with the previous model, the M320’s long wheelbase helps improve stability.
Cat M320 customers can achieve up to 17% lower maintenance costs compared with the previous design, helping reduce downtime and improve overall machine uptime.
Powered by the Cat C4.4 engine, the M320 meets China Nonroad Stage IV and Brazil MAR‑1 emission standards and emits equivalent to U.S. EPA Tier 3 and EU Stage IIIA. Automatic Engine Speed Control helps reduce fuel consumption by allowing the engine to enter idle mode when the machine is not working. Extended maintenance intervals further support reduced downtime over the life of the machine.
The M320 can travel at speeds up to 35 km/h (22 mph). Its advanced hydraulics system balances power and productivity while providing precise digging control. Auxiliary hydraulic options support a wide range of Cat attachments, with attachment commonality shared with the Cat 320 excavator.
