M318F and M320F Wheel Excavators Introduced

When designing the new Cat® M318F and M320F Wheel Excavators, Caterpillar solicited customer input for characteristics considered important.

Heading the list were initial quality and reliability, low operating costs, operator comfort and safety, simplicity of operation and maintenance, durability, and environmental friendliness.

The new models are designed around those goals, while retaining the best features of predecessor models, including the Cat Smartboom™, ride control, load-sensing hydraulics, dedicated swing pump, hydraulically driven cooling fan, large working envelope, and configuration/work-tool versatility.

Comfort and Safety

The exterior of the new models has been completely restyled, including a completely new ROPS-compliant operator’s cabin featuring higher pressurization, larger door with added glass, new windshield with parallel wipers, new mirrors (with a heated option), new rain visor and light protectors, a larger skylight, and a standard rearview camera housed in the redesigned counterweight as well as a right-side camera with a separate in-cab monitor.

Entering and exiting the cabin is now easier with redesigned three access steps and a new design door handrail. Inside the cabin, the left-hand console tilts to facilitate entering and leaving the seat, and the console includes an integral safety lever. Also new is the steering wheel, which is height adjustable and features a tilting column. The new cabin has an interior sound level of just 71 dB(A), and vibration levels have been reduced.

The standard lighting package for the new models now includes a counterweight light (enhancing the rearview camera function at night), three cabin-mounted lights, and light on the boom. Standard LED lights replace the previous halogen lighting for enhanced illumination, lower power consumption, and longer life.

Easy to operate, maintain and service

An automatic system, when enabled by the operator, senses machine parameters and locks the axle-oscillation function and sets the service brakes, readying the machine to dig. This feature reduces operator fatigue by removing the need to constantly press the brake pedal and results in added productivity. Brake and axle lock are automatically released when the operator presses the travel pedal again. Also, a new travel-lock system, engaged via the switch panel, combines implement-stop and swing-lock functions. For further convenience, cruise control is a standard feature allowing the operator to choose the very speed he wants and can be activated via the Quick-Access button on the monitor.

Versatility being one key attribute of wheel excavators, operators can adjust the machine to the task and to personal preference, hydraulic pressures and flows for work tools can be easily adjusted.

The M318F and M320F also incorporate a PIN-code anti-theft system. For operator convenience during short breaks in production, the system remembers the last code entered before engine shutdown and allows that code to remain active for a period of time.

Also, a new blade for the M318F and M320F has a redesigned profile, allowing the blade to remain parallel to the ground at any height and assisting material to roll more easily in front of the blade.

The engine in the new models, as in predecessor models, is longitudinally mounted with the cooling package forward of the engine, resulting in easy, ground-level access to routine maintenance points. An electric fuel-priming pump eliminates filling filters before installation. All the radiators are now grouped in the same compartment and the condenser can be tilted with no tool for ease of cleaning. Electrical and hydraulic components are now grouped in specific areas for ease of service and an automatic centralized greasing device (Auto-lube) is standard allowing operators to remain focused on the job.
