Biodiesel-Ready Fuel System

The C6.6 ACERT engine is equipped with an electronic-controlled high-pressure fuel system that includes an electric priming pump (lifting pump) and three-layer fuel hoses to allow the use of biodiesels up to B20 (biodiesel fuel 20% mixture meeting ASTM 6751 or EN 14214).

Cooling System

The cooling system features an air-to-air aftercooler and A/C condenser positioned for easy servicing; the fan automatically adjusts to ambient temperatures to help reduce fuel consumption and noise.

Speed and Power Control

The 320E LRR features speed control to maintain a constant speed - regardless of load - to improve fuel economy. Two different power modes are offered: high power and economy. The operator can easily change between modes through the monitor or console switch to meet the needs for the job at hand - all to help manage and conserve fuel.

Seats

The seat range includes air suspension, heated, and air cooled options. All seats include a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments to meet operator needs for comfort and productivity.

Controls

The right and left joystick consoles can be adjusted to meet individual preferences, improving operator comfort and productivity during the course of a day. With the touch of a button, one-touch idle reduces engine speed to help save fuel; touch it again or move the joystick and the machine returns to normal operating level.

Monitor

The 320E LRR is equipped with a 7" LCD (Liquid Crystal Display) monitor that's 40% bigger than the previous model's with higher resolution for better visibility. In addition to an improved keypad and added functionality, it's programmable to provide information in a choice of 42 languages to support today's diverse workforce. An “Engine Shutdown Setting” accessible through the monitor allows owners and operators to specify how long the machine should idle before shutting down the engine, which can save significant amounts of fuel. The image of the rearview camera is displayed directly on the monitor. Up to two different camera images can be displayed on the screen.

Power Supply

Two 12-volt power supply sockets are located near key storage areas for charging electronic devices.

Storage

Storage spaces are located in the front, rear, and side consoles. A specific space near the auxiliary power supply holds MP3 players and cell phones. The drink holder accommodates large mugs with handles, and a shelf behind the seat stores large lunch or toolboxes.

Automatic Climate Control

The climate control system features five air outlets with positive filtered ventilation, which makes working in the heat and cold much more pleasant.

Reduced Radius

The 320E LRR's tail swing radius is 2080 mm compared to 2830 mm on the 320E. When aligned with the tracks, working over the front, it does not extend beyond the track length allowing the 320E LRR to work well in road construction applications and other space-restricted areas.

Stability

The 320E LRR offers a stable platform for all applications. When compared to the 320E L, the 320E LRR delivers up to 16% additional lift over the side with the heavier counterweight. One of the main contributors is the use of an additional counterweight, which allows the balance of the machine to be comparable to a standard machine with a longer tail swing.

Comfort

While the length of the upper structure is reduced to accommodate the work at hand, the cab of the 320E LRR is the same size with all the amenities and attachments found inside the 320E L.

Hydraulic Horsepower

Hydraulic horsepower is the actual machine power available to do work through implements and work tools. It's much more than just the engine power under the hood - it's a core strength that differentiates Cat machines from other brands.

Hydraulic Pumps

The 320E LRR uses a two-pump, high-pressure hydraulic system to tackle the toughest work in short order. A highly efficient and simple back-to-back main control valve improves fuel consumption and allows for greater tool versatility.

Heavy Lift

The 320E LRR features a heavy lift function to give more lift capacity over the front. With a touch of a button, pressure increases and engine speed reduces to give better control in lifting those extra-tough-to-move materials like concrete pipe and road construction barriers.

Swing Priority Circuit

The swing priority circuit on the 320E LRR uses an electric valve that's operated by the machine's Electronic Control Module (ECM). Compared to using a hydraulic valve, an electric valve allows for more finely tuned control, which is critical during material loading.

Electric Boom Regeneration Valve

This valve minimizes pump flow when the boom lowers down, which helps improve fuel efficiency. It is optimized for any dial speed setting being used by the operator, which results in enhanced boom lowering speed for greater controllability.

Frame

The 320E LRR features a solid foundation that's built to absorb the stresses of every day work. The main frame utilizes high-tensile-strength steel and a one-piece swing table to improve strength and reliability. The X-shaped carbody is designed to resist bending and twisting forces. The upper frame includes reinforced mountings to support the Roll-Over Protective Structure (ROPS) cab; the lower frame is reinforced to increase component durability.

Undercarriage

The undercarriage is built to support various work applications. Precision-forged carrier rollers, press-fit pin master joints, and enhanced track shoe bolts improve durability and reduce the risk of machine downtime and the need and cost to replace components. Heavy-duty rollers and idlers are sealed and lubricated to extend service lift. Track links are assembled and sealed with grease to decrease internal wear and increase life compared to dry seal undercarriage. Also, a segmented two-piece guiding guard is now offered to help maintain track alignment and improve performance in multiple applications.

Counterweights

A 6.2 mt counterweight is standard. Integrated links enable easy removal of the counterweight for maintenance or shipping.

Booms and Sticks

The 320E LRR is offered with a 5.7 m reach boom and the R2.9B1 stick. Both boom and stick are made of high-tensile-strength steel using a large box section design with interior baffle plates and an additional bottom guard; both undergo ultrasound inspection to ensure weld quality and reliability. Other reinforced areas on the 320E LRR include thick multi-plate fabrications, castings, and forgings used in high-stress areas such as the boom nose, boom foot, boom cylinder, and stick foot. The boom nose pin retention method is a captured flag design for added durability. The front linkage pins' inner bearing surfaces are welded with a self-lubricated bearing, which helps extend service intervals and increase uptime.

An extensive range of Cat Work Tools for the 320E LRR includes buckets, compactors, grapples, scrap and demolition shears, multi-processors, pulverizers, and hammers. Each is designed to optimize the versatility and performance of your machine.

Buckets

Cat buckets are designed as an integral part of the 320E LRR system and feature new geometry for better performance. The leading edge has been pushed forward, resulting in more efficient filling and better operator control for greatly improved productivity. Wear coverage in the corners and side cutter and sidebar protector coverage are improved. All benefits are captured in a new bucket line with a new bucket naming convention. Caterpillar offers standard bucket categories for excavators. Each category is based on intended bucket durability when used in recommended application and material.

General Duty (GD)

GD buckets are for digging in low-impact, low-abrasion material such as dirt, loam, and mixed compositions of dirt and fine gravel.

Heavy Duty (HD)

The most popular bucket style, HD buckets are a good starting point when digging conditions are not well known like a wide range of impact and abrasion conditions including mixed dirt, clay, and rock.

Severe Duty (SD)

SD buckets are for higher abrasion conditions such as well shot granite and caliche. Red area on bucket image illustrates additional protection against wear as compared to a GD bucket.

Specialty Buckets

In addition to the standard four bucket categories, specialty bucket styles are available for the 320E LRR, each with a different purpose:
• Ditch Cleaning buckets for cleaning ditches, slope grading, and other finish work.
• Center-Lock Pin Grabber Performance buckets for maximum digging performance while keeping the versatility and convenience of a coupler.
• Wide Tip buckets for low impact material where leaving a smoother floor and minimal spillage are necessary.

Hydraulic Kits

Caterpillar offers field-installed hydraulic kits that are uniquely designed to integrate Cat Work Tool attachments with Cat excavators. Hoses and tubes are pre-made, pre-shaped, and pre-painted to make installation quick and easy.

Comprehensive Product Support

All Cat Work Tools are backed up by a world-wide network of well-stocked parts depots and highly experienced service and support personnel.

Cat® Grade Control Depth and Slope

This optional system combines traditional machine control and guidance with standard factory-installed and calibrated components, making the system ready to go to work the moment it leaves the factory. The system utilizes internal front linkage sensors - well protected from the harsh working environment - to give operators real-time bucket tip position information through the cab monitor (1), which minimizes the need and cost for traditional grade checking and improves job site safety. It also helps the operator complete jobs in fewer cycles, which means less fuel use.

Cat Product Link

This deeply integrated into the machine monitoring system is designed to help customers improve their overall fleet management effectiveness. Events and diagnostic codes as well as hours, fuel consumption, idle time, machine location, and other detailed information are transmitted to a secure web based application (2 and 3) called VisionLink™, which uses powerful tools to communicate to users and dealers.

Service Doors

Wide service doors and a one-piece hood provide easy access to the cooling and engine compartments. Both doors and hood feature enhanced hardware and a new screen design to help minimize debris entry.

Compartments

The compartments are designed to provide technicians with quick access to major components and regular service items like filters. The fresh air filter, for example, is located on the side of the cab to make it easy to reach and replace as needed.

Other Service Enhancements

The water separator with water level sensor has a primary fuel filter element located in the pump compartment near ground level. The fuel tank features a remote drain cock located in the pump compartment to make it easy to remove water and sediment during maintenance. The engine oil check gauge is situated in front of the engine compartment for easy access, and a uniquely designed drain cock helps prevent spills. Hydraulic lash adjusters automatically adjust valve opening and closing events to help reduce fuel consumption and engine noise. They also eliminate the need for a valve lash, which reduces maintenance for the customer.

ROPS Cab

The ROPS-certified cab allows a Falling Object Guard Structure (FOGS) to be bolted directly to it.

Sound Proofing

Improved sealing and cab roof lining lower noise levels by 5 dB inside the cab - a significant benefit to operators.

Anti-Skid Plates

The surface of the upper structure and the top of the storage box area are covered with anti-skid plates to help prevent service personnel and operators from slipping during maintenance.

Steps, Hand and Guard Rails

Steps on the track frame and storage box along with extended hand and guard rails to the upper deck enable operators to securely work on the machine.

Time Delay Cab and Boom Lights

After the engine start key has been turned to the “OFF” position, lights will be illuminated to enhance visibility. The time delay can vary from 0 to 90 seconds, which can be set through the monitor.

High Intensity Discharge (HID) Lights

Cab lights can be upgraded to HID for greater visibility.

Windows

Two windshield options are available: The 70/30 split configuration features an upper window equipped with handles on the top and both sides so the operator can slide it to store in the ceiling. The lower window is removable and can be stored on the left wall of the cab shell. The large skylight provides great overhead visibility, excellent natural lighting, and good ventilation. The skylight can be opened completely to become an emergency exit.

Monitor Warning System

The machine's advanced diagnostic system features a buzzer in the monitor to communicate to operators critical events like full filters or low hydraulic fluid levels so they can take immediate action.

Rearview Camera and Mirrors (ISO 5006)

The standard rearview camera is housed in the counterweight. The image projects through the cab monitor to give the operator a clear view of what is behind the machine.
