320E

Powered by the C6.6 ACERT™ (Tier 4 Interim electronic engine) (148 to 151 hp (ISO) NET. (+2.7%) NACD Equipped with a high-pressure common rail fuel system,Three power modes—high, standard, and economy—to help owners and operators manage productivity and fuel cost Automatic Engine Speed Control to reduce rpm when not under load to help save fuelFuel system built to accommodate biodiesel fuel up to B20Engine HoodThe new hood opens across the entire engine and cooling compartment (light weight)Regeneration“No Downtime.” Regeneration is transparent to the operator. Back Pressure Valve work in low idel or low temperature.Most maintenance items serviceable from ground levelWider, lighter service doors with sturdier hinges and latches; new door vent design to prevent debris entryRadiator, pump, and air cleaner compartments easy to access from the upper structurePrimary filter, water separator, and electric priming pump accessible at ground level Easy-to-remove engine oil filter and easy-to-check engine oil gauge located in pump and engine compartmentsCat Equipment Technician diagnostic connector moved to fuse and relay panel area just inside the cab door for easier accessPump CompartmentA service door on the right side of the upper structure allows for easy access to the pump, case drain filter, pilot filter, and fuelprimary filter with water separator. Also, T-tap points on the pump make hydraulic system adjustment easier. The engine oil filterand S.O.S sampling port for the engine oil and hydraulic oil are also situated in the pump compartment. UndercarraigeStandard, Long and Long Narrow available depending on regionStandard and heavy-duty track rollers, carrier rollers, idlers, and track shoesGrease-lubricated track link built to keep dirt and debris from entering space between pin and bushing, increasing component lifeIdler guard integrated into the track roller frame to maintain track alignment while traveling or working on slopesTrack frame sloped at a steep angle to reduce mud and debris accumulationFinal drive to contribute to better fuel economy; redesigned motor housing to prevent mud packingStandard and heavy-duty track rollers are available. Press-fit master link pin (compared to D Series slip-fit design) to improvedurability and decrease risk of downtime on NACD Lift up Configuration.Segmented two-piece guiding guard to maintain track alignment better in multiple applications than D Series half-track systemFinal Drive Improvements A new feature is a slot design on the motor housing to improve seal performance by preventing mud packing on the labyrinth, whichcan cause oil leaks.Counterweights 3.55MT CTWT for STD model, 4.6MT ton SLR and 5.4 MT for NACD Lift up configuration.Counterweight Lifting Eyes The lifing eye's are now recessed into the top of the counterweight and are no longer exposed. Note that the integrated links cannot be used for lifting the machine itself, and are not a replacement for the large machine lifting eyes offered as an attachment on DSeries machines.Rearview Camera Offers a rear view image on the standard monitor display. The rear view camera on the 320E is built in to the counterweight.Upper FrameStructure Upper frame (swing frame) reinforced to accommodate new ROPS cab and for NACD Lift up configuration.Hydraulics Main Control Valve Improved fuel efficiency (1-5.2%)New BTB valve/system (across all E series)+4% efficiency by reducing pressure drop.Open-center, two-pump negative flow control design with pilot operationMain pump pressure increase to significantly improve response to improve lifting capability in Lift mode.New back-to-back valve to eliminate oil flow restrictions, improving efficiency and powerComponents located closer together to reduce oil flow distance, increasing power to do more workElectric boom regeneration valve (compared to D Series’ hydraulic valve) to improve efficiency and cycle time for higherproductivity and lower owning and operating costSwing priority circuit with electric valve to enable greater control when loading materialImproved Electric Control Module (ECM) to handle increase in electrical control areas such as boom regeneration, negative flowcontrol, and after-treatment sensors that measure temperatures and soot levelsLockable hydraulic tank fill cap with integral breatherCapsule-type return filter with handle to help remove and change without oil spillage or contaminationHydraulic Tank The hydraulic tank fill cap has been improved to no longer require a tool to be removed, which let air in and out. The breather is nowan integral part of the cap, which can also be locked using the machine key to secure the tank against theft or vandalism.Hydraulic Return Filter The hydraulic return filter is located in the hydraulic tank compared to the D Series’ external location, which frees up space to moreeasily access the hydraulic pump. This filter is changed from the top service platform; if it clogs, a warning is displayed on themonitor inside the cab. The filter also has a handle to remove with ease and lowers the chance of contaminationHand & Guard Rails New ISO-compliant hand and guard rails are. The new handrail design in the battery compartment area helps service technicianswork from the track shoe. Handrails for climbing up to upper deck are extended, with one being added above the air cleanercompartment. Two guard rails are also provided on top of the fuel tank and hydraulic oil tank, and the track frame and storage boxhave large steps for climbing.Front Linkage Booms & Sticks Feature internal baffle plates for added durability; each boom and stick undergoes ultrasound inspection to ensure quality andreliability.Boom & Stick Durability High-tensile-strength sticks with baffle plates for added rigidity.Bucket Linkage The front linkage pins are the same diameter as the front linkage pins of the 320D. The boom, stick, and bucket pins are compatiblebetween the 320E and 320D.Extreme Service front package to operate in the harshest conditionsBoom nose retention changed to captured flag from D Series’ bolted flag for lighter weight and more durabilityWorktool Control There are no significant changes to the E Series tool control system that affect controllability or work tool performance.Transporation:The 320E carbody has a box section “X” structure like the 320D. New tie-down points on long (L) and long narrow (LN)undercarriages.Cab New Roll-Over Protective Structure (ROPS) with redesigned overhead guarding to protect operators9% wider skylight than D Series that’s removable for emergency exitOptional rearview camera that projects through the monitor to provide operator a clear field of viewThe open area around the engine cooling fan has been covered by a flat fan guard. This reduces the risk of coming in contact withthe fan during machine inspection or serviceCab Doors New doors are lightweight and more rigid providing improved durability.One Touch Idle The 320E is equipped with one-touch idle to reduce engine speed and conserve fuel. Located on the top of the right-hand joystickcontrol lever.Operator Station Sound Proofing The sound inside the 320E cab decreased by 3db to 69dbHID Lights Halogen boom and cab lights can be upgraded to HID (High Intensity Discharge) for greater visibility and safety; cab lights are timedelayed for nighttime visibility.WindowsThe cab features increased glass coverage for improved visibility while meeting the latest Roll-Over Protective Structure (ROPS)regulations.
