The Cat C6.4 with ACERT™ Technology introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology. The building blocks of ACERT Technology are fuel delivery, air management and electronic control. ACERT Technology optimizes engine performance while meeting emission regulations. With its proven technology, robust components and precision manufacturing, you can count on this engine to power up at start time and keep working productively all shift long.
The ADEM A4 electronic control module manages fuel delivery to get the best performance per liter of fuel used. The engine management system provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It tracks engine and machine conditions while keeping the engine operating at peak efficiency.
The Cat C6.4 features electronic controls that govern the fuel injection system. Multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. This translates into more work output for your fuel cost.
The cooling fan is directly driven from the engine. A high ambient cooling package is available which will increase cooling capacity from 43°C to 52°C (109° F to 125° F).
To optimize efficiency of hydraulic performance, the hydraulic components are located close together, which reduces friction loss and pressure drops in the lines.
The 320D features the addition of a Heavy Lift, which increases system pressure to 36,000 kPa (5221 psi), giving even more lift capacity over the front. Heavy Lift, if equipped, is activated by depressing the soft switch on the right hand console. While Heavy Lift is engaged, the engine speed is reduced, which allows better control while lifting objects.
The pilot pump is independent from the main pumps and controls the front linkage, swing and travel operations.
The hydraulic cross sensing system utilizes each of two hydraulic pumps to 100 percent of engine power, under all operating conditions. This improves productivity with faster implement speeds and quicker, stronger pivot turns.
Boom and stick regeneration circuit saves energy during boom-down and stick-in operation which increases efficiency, reduces cycle times and pressure loss for higher productivity, lower operating costs and increased fuel efficiency.
The auxiliary valve is standard on the 320D. Control Circuits are available as attachments, allowing for operation of high and medium pressure tools such as shears, grapples, hammers, pulverizers, multi-processors and vibratory plate compactors.
Snubbers are located at the rod-end of the boom cylinders and both ends of the stick cylinders to cushion shocks while reducing sound levels and extending component life.
The monitor is a full color Liquid Crystal Display that gives you vital operating and performance information, alerts in text, all in a simple, east to navigate format.
To enhance operator comfort and productivity, the cab includes a lighter, drink holder, coat hook, service meter, literature holder, magazine rack and storage compartment.
Joystick controls have low lever effort and are designed to match the operator's natural wrist and arm position.
For added safety, this lever must be in the operate position to activate the machine control functions.
Fully automatic climate control adjusts temperature and flow, and determines which air outlet is best in each situation with a touch of a button.
The bucket linkage pins for the Mass Excavator configuration have been enlarged to improve reliability and durability. All the pins in the front linkages have thick chrome plating, giving them high wear and corrosion resistance.
The power link has been redesigned to be more robust and improve durability of the bucket linkage. An integrated lift eye has been added, which makes it easier to use than the prior series, especially when lifting objects. Lifting from the lift eye optimizes the lift capacity as it lowers the load point and maximizes the use of the boom cylinders.
Choose from a wide variety of tips that maximize bucket and machine performance. Sidecutters and sidebar protectors are also available.
The 320D offers the most options available to equip your 320D to best match your application and work environment requirements. From track shoe size to guarding packages to operator comfort options, Caterpillar offers more options.
320D service and maintenance intervals have been extended to reduce machine service time and increase machine availability.
The design and layout of the 320D was made with the service technician in mind. Many service locations are easily accessible at ground level allowing critical maintenance to get done quickly and efficiently.
The air filter features a double-element construction for superior cleaning efficiency. When the air cleaner plugs, a warning is displayed on the monitor screen inside the cab.
A service door on the right side allows for ground level access to the hydraulic pump, engine oil filter, case drain and pilot filters.
The side-by-side placement of the radiator and oil cooler makes core cleaning easy. The aftercooler is located in front of the radiator/oil cooler. The condenser for the air conditioning system is mounted in front of the radiator/oil cooler and under the aftercooler. A radiator screen is provided between the radiator/oil cooler and aftercooler to prevent plugging by debris. In addition, there is wider clearance between the radiator/oil cooler and aftercooler, so debris can be easily blown off by a wand, or air nozzle. A cooling fan is connected directly to the engine.
A concentrated remote greasing block on the boom delivers grease to hard-to-reach locations on the front.
The hydraulic return filter, a capsule filter, is situated outside the hydraulic tank. This filter prevents contaminants from entering the system when hydraulic oil is changed and keeps the operation clean.
Anti-skid plate covers top of storage box and upper structure to prevent slipping during maintenance.
The 320D is equipped with S•O•SSM sampling ports and hydraulic test ports for the hydraulic system, engine oil, and coolant. A test connection for the Cat Electronic Technician (Cat ET) service tool is located in the cab.
