Performance
- The powerful, efficient Cat® C4.4 mechanical engine offers up to 14% lower fuel consumption than the model it replaces with no loss of lifting or digging force.
- The low-pressure fuel system with an electrically controlled governor allows the engine to be more robust with quality fuel.
- Boom and stick regeneration valves help reduce fuel consumption.
- Highly efficient hydraulic pumps deliver optimal power to suit general construction applications.
- The machine’s China Nonroad Stage III and U.S. EPA Tier 3/EU Stage IIIA equivalent engine can run on biodiesel up to B20 that meets ASTM 6751 standards.
Versatility
- Site prep and finishing work are quick and easy with a wide range of Cat work tools.
- Utility work is fast and flawless with a Cat bucket and compactor.
- See the whole money-making attachment line for your machine at www.cat.com/attachments.
Safety
- The hydraulic activation lever safely locks out all hydraulic functions.
- Anti-skid plating and countersunk bolts reduce slipping in severe conditions and during routine checks.
- A full-length firewall separates the pump compartment from the engine.
Durability
- The modified X-frame structure provides a long service life.
- Robotically welded booms and sticks with internal baffle plates are standard.
- Greased track link between pins and bushings increases undercarriage life and reduces noise.
Ease of Operation
- The cab is ergonomically designed cab with easy-to-reach controls.
- Multiple seat and joystick adjustment options enhance comfort.
- Excellent work site visibility from the cab enhances productivity and safety.
- Low-effort joystick controls reduce operator fatigue.
- The automatic climate control system with 10 vents maximizes comfort.
Serviceability
- Most service locations can be accessed at ground level.
- The fuel filtration system has two filters, both located in the radiator compartment, rather than three filters as in the 312D, lowering O&O costs and simplifying service.
- Remote-mounted filters reduce the time to service the machine.
- Pressure taps and S·O·SSM ports help maximize uptime.
Technology
- Cat Connect technology solutions increase production and minimize operating costs.
- Link technologies wirelessly connect you to your job site providing essential business information (VisionLink®, Product Link™).
