The new Cat M320 wheeled excavator has been announced for Europe, North America, Australia, New Zealand and South Korea. The machine optimizes performance and efficiency, with up to 9% more swing torque than its predecessor, the Cat M320F.
It also has a longer wheelbase to increase operating stability and improve machine ride when roading to the next job site at speeds reaching 35 km/h (21.7 mph). Multiple potential applications are envisaged including utility work, trenching, and waste handling.
Improvements to the hydraulic system increase machine efficiency when working with a range of Cat attachments. Upgrades in machine design reduce the time it takes for daily maintenance plus extended filter life and longer service intervals maximize machine uptime availability at the job site while lowering ownership costs.
Delivering performance and production, the new M320 is powered by the 129.4-kW (174-hp) Cat C4.4 engine that meets EU Stage V and U.S. EPA Tier 4 Final emissions standards. Efficiency increasing standard features like one-touch low idle with automatic engine speed control, auto engine idle shutdown and on-demand electric cooling fans combine to conserve both diesel and diesel exhaust fluid (DEF) to lower operating costs. Capable of running up to B20 biodiesel, the machine offers a standard high-ambient temperature capability of 50˚ C (125˚ F) and cold-start capability of -18˚ C (0˚ F) for completing projects in a range of operating environments.
More efficiently multitasking, the new M320 features a dedicated swing pump to provide consistent power. The advanced hydraulic system automatically balances power and efficiency to give operators more machine control for precise working requirements. Its unique heavy lift mode feature boosts lifting capacities to more efficiently handle heavy loads, increasing machine flexibility.
