Performance and Productivity
The C7.1 Cat engine complies with the European Stage IIIA emission standard. The engine's fuel system is suitable for all fuel qualities worldwide and ensures exceptionally low fuel consumption, both during work and while traveling. The idle control by simple pressure and the automatic engine speed control allow for reducing the engine speed in case of inactivity, thus reducing fuel consumption and noise levels. Three working modes: power mode, eco mode, and travel mode. The constant power strategy ensures a quick response to load changes while providing the same power. The choice of booms and arms allows for a perfect match between excavation forces and reach in all applications. Even during rotation, the dedicated turret pump allows for faster and smoother combined movements when using equipment.
Develop Your Skills
Several configurations are possible to meet the needs of your applications thanks to a wide range of arms, booms, blades or undercarriages with stabilizers. Ultra-mobile, the M320D2 model can move at a speed of up to 37 km/h. The standard unidirectional high-pressure hydraulic circuit allows customers to install equipment such as hammers without adding additional pipelines. Ten pressure discharge and hydraulic pump flow settings can be pre-programmed on the monitor, allowing equipment to be connected more quickly and easily (optional). A lifting eye in the bucket linkage, the heavy lifting mode, and the overload warning signal allow drivers to safely lift heavy loads. The wide range of Cat equipment allows tackling all types of tasks.
Driver Comfort and Safety
The ROPS cabin structure and the driver protection frame (upper and front protections) are available. The cabin is designed ergonomically with controls ideally placed and easy to use, with the number reduced to a minimum. Available as an option, the air suspension seat, with automatic adjustment based on weight and heated cushions, improves driver comfort and productivity. Safety is enhanced by the panoramic visibility provided by the large glass surfaces and the full-sky roof, as well as by the image from the rear camera, which is standard and displayed on the color monitor. Low noise levels thanks to the variable speed fan and remote cooling circuit.
Lower Maintenance Costs
Replacing the fuel filter every 500 hours (reduced to 250 hours if the fuel quality is below standard) helps reduce maintenance costs. All daily maintenance points are accessible from the ground. Clean design, with color-coded and numbered electrical cables, protected by thick braided sleeves to facilitate maintenance operations to the maximum. Centralized and minimized greasing points. ES XT™-6 Cat resistant hoses reducing the risk of leakage that can harm machine performance. Rigidity and long lifespan thanks to effective transmission protection and extra-strong axles. Standard heavy-duty batteries for better cold start performance.
Integrated Cat Technologies
Increase production and reduce operating costs through Cat Connect technology solutions. Link technologies allow you to wirelessly connect to your job site, giving you access to the following information: machine location, service hours, fuel consumption, downtime, and incident codes.
