CATERPILLAR has launched two new wheeled excavators.
The Cat M319 boasts a short front-end design and tail swing to aid work in confined areas. Described as delivering up to 15% more swing torque than previous models, the digger features a dedicated swing pump which Cat said provides ‘more consistent power for better multi-tasking capabilities’.
Powered by the 128-kW (171-hp) Cat C4.4 engine, the M319 meets EU Stage V emissions standards and offers solutions such as Eco mode to minimise fuel consumption in less demanding applications.
The machine can travel between sites at speeds reaching 35 km/h. To increase flexibility, auxiliary hydraulic options of high- and medium-pressure circuits with one/two-way pressure flow allow contractors to tailor configuration for using a wide range of Cat attachments.
The ‘reengineered’ cab has a new 240mm touchscreen monitor with jog dial. Operators can programme joystick configuration and power preferences. Cab entry and exit has been eased with a new tilt-up left console.
With available Deluxe and Premium cab designs, the Deluxe comes standard with a heated and air-adjustable seat, while the Premium offers a seat that is heated, ventilated and automatically adjusts.
Safety features include standard rear view and right-side cameras, along with large cab windows with small cab pillars, helping to improve visibility. An optional 360◦ visibility system combines input from multiple cameras around the machine. A new flat engine hood design also improves visibility.
The other new wheeled digger is the Cat M320, which offers up to 9% more swing torque than the Cat M320F. A longer wheelbase is said to increase operating stability.
Caterpillar said improvements to the hydraulic system increase machine efficiency when working with a range of Cat attachments, while upgrades in machine design reduce the time it takes for daily maintenance.
The M320 is powered by the 129.4-kW (174-hp) Cat C4.4 engine, which meets EU Stage V emissions standards. Features include one-touch low idle with automatic engine speed control, auto engine idle shutdown and on-demand electric cooling fans.
Standard Product Link technology improves fleet management and servicing by recording and reporting 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 still operating.
Two larger Next Gen cab designs – Deluxe and Premium – are available. All controls are positioned in front of the operator and the machine can be started in several ways: via pushbutton start; a Bluetooth key fob; or the unique Operator ID function.
As with the Cat M319, the machine features standard rear view and right-side cameras, along with large cab windows with small cab pillars, and an optional 360◦ visibility system combining input from multiple cameras around the machine.
