Load-sensing hydraulic system provides fast cycle times, increased lift capacity and high bucket and stick forces to maximize your productivity in any job. Dedicated Swing Pump A dedicated variable displacement piston pump and fixed displacement piston motor power the swing drive. This closed hydraulic circuit maximizes swing performance without reducing power to the other hydraulic functions, resulting in smoother combined movements. Heavy Lift Mode This mode maximizes lifting performance by boosting the lifting capability of the excavator by 7%. Adjustable Hydraulic Sensitivity This function...

Reduces stress and vibrations transmitted to the machine and provides a more comfortable environment. Rock Scraping Scraping rock and finishing work is easy and fast. SmartBoom simplifies the task and allows the operator to concentrate on stick and bucket, while boom freely goes up and down without using pump flow. Hammer Work The front parts automatically follow the hammer while penetrating the rock. Blank shots or excessive force on the hammer are avoided resulting in longer life for the hammer and the machine. Similar advantages with vibratory plate Truck Loading Loading trucks from a bench...

Operator Comfort The interior layout maximizes operator space, provides exceptional comfort and reduces operator fatigue. Interior Operator Station Improved visibility and ergonomics are some of the many features of the D Series Wheel Excavators. The operator station provides maximum space and is designed for simplicity and functionality. Frequently used switches are centralized and are situated on the right-hand switch console. The left-hand seat console controls dozer blade and/or outriggers, and is tiltable for easy access to the cab. The fully automatic climate control adjusts temperature...

The new compact color monitor displays information in local language that is easy to read and understand. Functions include: 2 times 5 programmable "Quick Access" buttons for one-touch selection of favorite functions. Filter and oil change warnings are displayed when the number of hours reaches the maintenance interval. Tool select function allows the operator to select up to 10 predefined hydraulic work tools. Adjustable braking characteristics enable the operator to select three levels of travel motor retarder aggressiveness when releasing the travel pedal. Provides a rear camera view that...

Undercarriage and axle design provides maximum strength, flexibility and mobility on wheels. Increased Travel Speed The maximum travel speed for the M313D is 37 km/h (23 mph), reducing travel time between sites and increasing productivity. Heavy-Duty Axles and Stabilizers The D Series undercarriage provides rigidity and long life. Effective hydraulic line routing, transmission protection and heavy-duty axles make the undercarriage perfect for wheel excavator applications. The front axle offers wide oscillating and steering angles. The transmission is mounted directly on the rear axle for protection...

Designed for maximum flexibility to keep production high on all jobs. Booms and sticks are welded, box section structures with thick, multiplate fabrications in high stress areas, for rugged performance and long service life. The choice of three booms and four sticks provides the right balance of reach and digging forces for all applications. Variable Adjustable (VA) Boom The VA boom offers improved right side visibility and machine reading balance. When working in tight quarters or lifting heavy loads, the VA boom offers the best flexibility. One-Piece Boom The one-piece boom fits best for all...

Work Tools A wide variety of Work Tools help optimize machine performance. Work Tools Cat work tools are designed to function as an integral part of your excavator and to provide the best possible performance in your particular application. All work tools Quick Couplers Quick Couplers enable the operator to simply release one work tool and connect to another, making your hydraulic excavator highly versatile. Productivity also increases, as a carrier no longer needs to be idle between jobs. Caterpillar offers hydraulic and spindle quick coupler versions. Caterpillar offers a wide range of specialized...
