Exceptional power and fuel efficiency
Cat C7.1 ACERTThe Cat C7.1 with ACERT Technology gives the 320D2 FM exceptional power and fuel efficiency unmatched in the industry. The forestry designed hydraulics give the 320D2 FM power, efficiency and controllability unequaled in the industry for consistently high performance in all forestry applications.
PerformanceThe C7.1 ACERT engine replaces the previous C6.4 ACERT engine. Performance is maintained while fuel efficiency is improved, lowering owning & operating costs.
Automatic Engine Speed ControlAutomatic engine speed control is activated during no-load or light-load conditions which reduces engine speed to minimize fuel consumption.
ADEM™ A4 Engine ControllerThe 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.
Electronic Control ModuleThe Electronic Control Module (ECM) works as the “brain” of the engine’s control system, responding quickly to operating variables to maximize engine efficiency. Fully integrated with sensors in the engine’s fuel, air, coolant, and exhaust systems, the ECM stores and relays information on conditions such as rpm, fuel consumption, and diagnostic information.
Fuel DeliveryThe Cat C7.1 ACERT features electronic controls that govern the fuel injection system, and features an improved filtration system to ensure good reliability to fuel injection system components. Intervals have been extended and the number of filters reduced to maximize your profit potential.
Cooling SystemThe cooling fan is directly driven from the engine. An optional programmable reversible fan allows for radiator blowout, to increase service intervals and to maintain engine operational temperatures. The optimum fan blade pitch is calculated based on the target engine speed, coolant temperature, and hydraulic oil temperature. The Cat C7.1 ACERT delivers a completely new layout with improved cooling system.
Air CleanerThe radial seal air filter features a double-layered filter core for more efficient filtration and is located in a compartment behind the cab. A warning is displayed on the monitor when debris is plugging filter above a preset level.
PrefilterAn optional air cleaner Prefilter is available for the 320D2 FM. This Prefilter reduces debris ingestion into air cleaner filters, reducing plugging and extending air filter service intervals.
Noise Reduction TechnologiesThe engine mounts are rubber-isolating mounts matched with the engine package. Further noise reduction has been achieved through design changes to the isolated top cover, oil pan, multiple injection strategy, insulated timing cover, sculpted crankcase and gear train refinements.
Power and control needed for a variety of applications
Component LayoutThe 320D2 FM hydraulic system and component locations have been designed to provide a high level of system efficiency. The main pumps, control valves and hydraulic tank are located close together to allow for shorter tubes and lines between components that reduce friction and pressure drops in the lines. The layout further provides greater operator comfort by placing the radiator on the cab side of the upper structure. This allows incoming air to enter the engine compartment from the operator side and hot air and corresponding engine sound to exit on the opposite side away from the operator. This reduces engine compartment heat and sound being transmitted to the operator.
Pilot SystemThe pilot pump is independent from the main pumps and provides pilot oil to control all the front linkage, swing and travel valve functions.
Hydraulic Cross Sensing SystemThe hydraulic cross sensing system improves productivity with fast implement speeds and quick pump response.
Boom and Stick Regeneration CircuitBoom and stick regeneration circuits save 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.
Swing SystemNew improved swing drive system provides 20% higher swing torque. Better swing performance improves productivity and operator efficiency.
ControllabilityThe hydraulic system offers precise control to the 320D2 FM reducing operator fatigue, improving operator effectiveness and efficiency, which ultimately translates into enhanced performance.
Auxiliary HydraulicsThe auxiliary valve is standard on the 320D2 FM. Various Control Circuits are available as attachments, allowing for operation of a large variety of work tools.
Hydraulic Cylinder SnubbersSnubbers are located at the rod-end of the boom cylinders and both ends of the stick cylinders to cushion shocks, reduce sound and increase cylinder life, increasing uptime and productivity.
Maximizes space, provides exceptional comfort, excellent sightlines, and reduces operator fatigue
Operator StationThe workstation is spacious, quiet and comfortable, assuring high productivity during a long work day. Controls, joysticks and an ergonomically designed seat are strategically placed to reduce operator fatigue.
MonitorThe new monitor is a full-color Liquid Crystal Display (LCD). Monitor is equipped with warning lamp and buzzer for critical engine oil pressure, coolant temperature and oil temperature. Filters and fluid change intervals are available in the main menu. The monitor angle can be adjusted to minimize sun glare. Compared to 320D Series monitor, the new monitor on the 320D2 FM has a 40% larger screen, with a four times increased resolution display. Information language capability increased from 28 to 42 languages to support today’s diverse workforce.
Pre-Start CheckPrior to starting the machine, the system will check for low fluid levels for the engine oil, hydraulic oil and engine coolant and warn the operator through the monitor in the event display area.
Gauge DisplayThree analog gauges, fuel level, hydraulic oil temperature and coolant temperature, are displayed in this area.
Event DisplayMachine information is displayed in this area with both icon and language.
Multi-Information DisplayThis area is reserved for displaying various information which is convenient for the operator. The “Cat” logo is displayed when no information is available to be displayed.
SeatA comfortable air suspension seat provides a variety of adjustments to suit the operator’s size and weight including fore/aft, height settings. Wide adjustable armrests and a retractable seat belt are also included.
Joystick ControlJoystick controls have low lever effort and are designed to match the operator’s natural wrist and arm position. The operator can operate joystick controls with an arm on the armrest and the horizontal and vertical strokes have been designed to reduce operator fatigue. Exclusive proportional control and push buttons are programmable to operator personal preferences, allowing maximum productivity.
Hydraulic Activation Control LeverFor added safety, this lever must be in the operate position to activate the machine control functions.
ConsoleConsoles feature a simple, functional design to reduce operator fatigue, ease of switch operation and excellent visibility.
SkylightA skylight with sunshade provides excellent upwards visibility.
