Engine

Reduced emissions, economical and reliable performance

Cat® C6.6 ACERT™ Engine

The Cat C6.6 ACERT engine delivers more horsepower using signiicantly less fuel than the previous series engine.

Emissions Solution

Equipped to meet U.S. EPA Tier 4 Interim emission standards, the 320E’s C6.6 ACERT engine features an aftertreatment regeneration solution that requires no operator intervention. The regeneration process automatically starts once the iltering system reaches a certain level – with no interruption to machine performance or the work process.

Biodiesel-Ready Fuel System

The C6.6 ACERT engine is equipped with an electroniccontrolled high-pressure fuel system that includes an electric priming pump and three-layer fuel hoses to allow the use

of biodiesel (meeting ASTM 6751 or EN 14214) up to B20 (biodiesel 20% mixture).

Cooling System

The cooling system features an air-to-air aftercooler and A/C condenser that tilt up and swing out of the way for easy servicing; the viscous fan automatically adjusts to ambient temperatures to help reduce fuel consumption and noise.

Speed and Power Control

The 320E features speed control to maintain a constant speed – regardless of load – to improve fuel economy. Three different power modes are offered: high power, standard power, and economy power. 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.

	to provide information in a choice of 42 languages to
1	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
	signiicant 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

2Storage spaces are located in the front, rear, and side consoles. A speciic 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 ive air outlets with positive iltered ventilation, which makes working in the heat and cold much more pleasant.

Hydraulics

Power to move more dirt, rock, and debris with speed and precision

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.

Main Control and Auxiliary Valves

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

Electric Boom Regeneration Valve

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

Heavy Lift

The 320E features a heavy lift mode, which increases machine system pressure to improve lift over the front of the machine – a nice beneit in challenging situations. The system’s pressure increase combined with a reduction in engine speed and heavier

counterweight option give operators better control when lifting robust objects like concrete pipe and road construction barriers.

Structures & Undercarriage

Built to work in rugged environments

Frame

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

Fixed gauge long undercarriage systems are available to support various work applications. Heavy-duty track

rollers, precision-forged carrier rollers, press-it 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. Also, a segmented twopiece guiding guard is now offered to help maintain track

alignment and improve performance in multiple applications.

Counterweights

Three counterweight options are available: 3.55 mt (3.9 ton), 4.6 mt (5.1 ton) for super long reach, and 5.4 mt (5.9 ton) for heavy counterweight coniguration. Integrated links enable easy removal of the counterweight for maintenance or shipping.

Front Linkage

Made for high stress and long service life

Booms and Sticks

The 320E is offered with a range of booms and sticks (see list below). Each is built with internal bafle plates for added durability, and each undergoes ultrasound inspection to ensure weld quality and reliability.

Large box-section structures with thick, multi-plate fabrications, castings, and forgings are used in high-stress areas such as the boom nose, boom foot, boom cylinder, and stick foot to improve durability.

The boom nose pin retention method is a durable captured lag design. Boom durability is improved with a number of plate thickness changes. Also, the front linkage pins’ inner bearing surfaces are welded, and a self-lubricated bearing is used to extend service intervals and increase uptime.

Selections

There are three basic boom options: HD, ES, and SLR. Sticks match the boom descriptions and applications below:

•HD = Heavy Duty – This type of boom is designed to balance reach, digging force, and bucket capacity. It covers the vast majority of applications such as digging, loading, trenching, and working with hydraulic tools.

•ES = Extreme Service – This type of boom is best used for demolition or extreme applications where stress loads on the boom are increased. It should be used for demanding, harsh applications like 100% rock and extensive hammer use.

•SLR = Super Long Reach – This front offers reaches to over 51 feet. It is well suited for ditch cleaning applications.

Work Tools

Dig, hammer, rip, and cut with conidence

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

Quick Couplers

Quick couplers allow one person to change work tools in seconds for maximum performance and lexibility on a job site. One machine can move rapidly from task to task, and a leet of similarly equipped machines can share a common work tool inventory.

Cat Center-Lock™ Pin Grabber Coupler

Center-Lock is the pin grabber style coupler featuring a patented locking system. A highly visible lock clearly shows the operator when the coupler is engaged or disengaged from the bucket or work tool.

Buckets

Cat buckets are designed as an integral part of the 320E and feature new geometry for better performance. The leading edge has been pushed forward, resulting in more eficient illing and better operator control for greatly improved productivity. Wear coverage in the corners and side cutter and sidebar protector coverage are improved. All beneits 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. Buckets are available as pin-on or can be used with a quick coupler.

General Duty (GD)

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

of dirt and ine 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 that include 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, each with a different purpose:

•Ditch Cleaning buckets for cleaning ditches, slope grading, and other inish 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 loor and minimal spillage are necessary.

Hydraulic Kits

Caterpillar offers ield-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.

Integrated Technologies

Solutions that make work easier and more eficient

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 dealers can upgrade the system to full threedimensional control by adding proven Cat AccuGrade™ positioning technologies, including GPS and Universal Total Station (UTS).

Cat Product Link

This optional system is deeply integrated into the machine monitoring system and is designed to help customers improve their overall leet 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.
