328D LCR Hydraulic Excavator

Increased work tool options, new powerful engine and easier operation lead to increased productivity and lower operating costs.

C7 with ACERT Technology

Built for power reliability, economy and low emissions.

Cat C7 ACERT

The Cat C7 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 U.S. EPA Tier 3 engine emission regulations.

Performance

The 328D LCR, equipped with the C7 engine with ACERT Technology, provides 8 more horsepower as compared to the 3126B ATAAC HEUI in the 325C LCR.

Automatic Engine Speed Control

The twostage, onetouch control maximizes fuel efficiency and reduces sound levels.

ADEM A4 Engine Controller

The ADEM A4 electronic control module manages fuel delivery to get the best performance per liter gallon 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 Module

The Electronic Control Module ECM works as the brain of the engines control system, responding quickly to operating variables to maximize engine efficiency. Fully integrated with sensors in the engines fuel, air, coolant, and exhaust systems, the ECM stores and relays information on conditions such as rpm, fuel consumption, and diagnostic information.

Fuel Delivery

The Cat C7 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.

Cooling System

The cooling fan is directly driven from the engine. An electrically controlled viscous clutch fan is utilized to reduce fan noise. The optimum fan speed is calculated based on the target engine speed, coolant temperature, hydraulic oil temperature and actual fan speed. The 328D LCR incorporates side by side cooling, allowing easy access to keep the cooling cores free of debris.

Air Cleaner

The radial seal air filter features a doublelayered filter core for more efficient filtration and is located in a compartment behind the cab. A warning is displayed on the monitor when dust accumulates above a preset level.

Noise Reduction Technologies

The engine mounts are rubberisolating 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.

Hydraulics

Cat hydraulics deliver power and precise control to keep material moving.

Component Layout

The 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. This allows for shorter tubes and lines between components, which reduce friction loss, 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. Hot air and corresponding engine sound exits on the opposite side away from the operator. This reduces engine compartment heat and sound being transmitted to the operator.

Pilot System

The pilot pump is independent from the main pumps and controls the front linkage, swing and travel operations.

Hydraulic Cross Sensing System

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

Boom and stick regeneration circuit saves energy during boomdown and stickin operation. This increases operator efficiency, reduces cycle times and pressure loss. Benefits include higher productivity, lower operating costs and increased fuel efficiency.

Auxiliary Hydraulic Valve

The auxiliary valve is standard on the 328D LCR. Control Circuits are available as attachments, allowing for operation of high and medium pressure tools. These include shears, grapples, hammers, pulverizers, multiprocessors and vibratory plate compactors.

Hydraulic Cylinder Snubbers

Snubbers are located at the rodend of the boom cylinders and both ends of the stick cylinders. Benefits include reducing sound levels, cushion shocks while extending component life.

Operator Station

Designed for comfort, simple and easy operation, the 328D LCR allows the operator to focus on production.

Operator Station

The workstation is spacious, quiet and comfortable, assuring high productivity during a long workday. The attachment switches, key switch and throttle dial are conveniently located on the righthand wall. The monitor is easy to see and maximizes visibility.

Monitor

The monitor is a full color 400x234 pixels Liquid Crystal Display LCD graphic display. The angle can be adjusted to minimize sun glare and has the capability of displaying information in twentyseven different languages.

PreStart Check

Prior to starting the machine, the system will check for low fluid levels. These include engine oil, hydraulic oil and engine coolant. The event display area warns the operator if one of the conditions exists.

Gauge Display

Three analog gauges, fuel level, hydraulic oil temperature and coolant temperature, are displayed in this area.

Event Display

Machine information is displayed in this area with the icon and language.

Multiinformation Display

The joystick controls are designed for low lever effort and match operators natural wrist and arm position. The operator can operate the joystick controls with an arm on the armrest. Horizontal and vertical strokes have been designed to reduce operator fatigue.

Hydraulic Activation Control Lever

For added safety, this lever must be in the operate position to activate the machine control functions.

Automatic Climate Control

Fully automatic climate control adjusts temperature and flow, and determines which air outlet is best in each situation with a touch of a button.

Console

Redesigned consoles feature a simple, functional design to reduce operator fatigue, ease of switch operation and excellent visibility. Both consoles have attached armrests with height adjustments.

Cab Exterior

The exterior design uses thick steel tubing along the bottom perimeter of the cab, improving the resistance of fatigue and vibration. This design allows the FOGS to be bolted directly to the cab, at the factory or as an attachment later, enabling the machine to meet specifications and job site requirements.

Cab Mounts

The cab shell is attached to the frame with viscous rubber cab mounts, which dampen vibrations and sound levels while enhancing operator comfort.

Windows

All glass is affixed directly to the cab for excellent visibility eliminating window frames. The upper front windshield opens, closes and stores on the roof above the operator with a onetouch action release system.

Wipers

Pillarmounted wipers increase the operators viewing area and offer continuous and intermittent modes.

Skylight
