New Cat wheeled excavators offer increased swing torque, reduced maintenance costs

Caterpillar has released two new wheeled excavators—the M319 and the M320.

The new Cat M319 wheeled excavator features a short front-end design and tail swing to efficiently work in confined areas. Delivering up to 15 percent more swing torque than previous models, the Next Gen excavator also features a dedicated swing pump to improve operating efficiency by providing more consistent power for better multitasking capabilities.

Powered by the 128-kW (171-hp) Cat C4.4 engine, the M319 tailors performance and production to jobsite needs while meeting EU Stage V and U.S. EPA Tier 4 Final emissions standards. With features like Eco mode to minimize fuel consumption in less demanding applications, the excavator uses up to 5 percent less fuel than previous models, lowering long-term owning and operating costs.

The new M319 quickly travels between sites at speeds reaching 35 km/h (21.7 mph). With a tail swing radius of 6 feet, 3 inches, operators can complete dig, swing and dump tasks with limited side overhang when working on tight jobsites.

The reengineered cab delivers an enhanced operator experience. The new large, 240-mm (10-inch) touchscreen monitor with jog dial delivers intuitive navigation of machine controls. Operators can program joystick configuration and power preferences, and the new excavator recalls specific settings based on the unique Operator ID.

Cab entry and exit is much easier with a new tilt-up left console. Featuring advanced viscous mounts, the M319 reduces machine vibration feed-back to the cab, reducing operator fatigue. Easy-to-reach controls increase comfort, while auto axle lock detects when the service brake must be locked or unlocked to reduce the number of actions required by the operator.

Ground-level daily maintenance points and upper-level service platform help to increase safety when working on the M319. A standard hydraulic lockout lever isolates all hydraulic and travel functions, while swing lock prevents the front linkage from moving during travel.

Cat M320 wheeled excavator offers a longer wheelbase and extended service intervals

The new Cat M320 wheeled excavator optimizes performance and efficiency at the jobsite with up to 9 percent more swing torque than the Cat M320F. Its longer wheelbase increases operating stability and improves machine ride when roading to the next jobsite at speeds reaching 35 km/h (21.7 mph).

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, while extended filter life and longer service intervals maximize machine uptime at the jobsite.

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. 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.

For more efficient 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.

The new M320 design saves owners up to 5 percent in maintenance parts with its new, longer-lasting filters. Offering a 50 percent longer service life than previous filter designs, the new hydraulic oil filter features anti-drain valves to safeguard from contaminating the oil during replacement. Two fuel filtration levels better protect the engine from dirt particles in the diesel.

All daily maintenance points are quickly and safely checked from ground level. Reducing service time, the M320 features centralized grease points with an available automatic lubrication system option for the implement and swing system. The operator conveniently tracks machine maintenance intervals and filter life from inside the cab on a touchscreen monitor to improve maintenance planning efficiency.

Standard Product Link technology on the M320 improves fleet management and excavator servicing by recording and reporting critical operating data and machine fault codes to key personnel. New Remote Troubleshoot allows the dealer to run diagnostic testing of fault codes from the office while the machine is operating, potentially saving a trip to the jobsite.
