BENEFITS & FEATURES
Compact Radius
The 328D LCR has been designed to rotate with a minimal amount of counterweight hanging over the tracks, which allows it to work in tight, confined areas.


Compact Radius

Space Restriction
The increasing need to work within space-restricted areas has created a demand for larger excavators that can also work within tighter quarters and provide greater productivity. The newest addition to this lineup of compact radius (CR) excavators is the 328D LCR.

Productivity
Even though the 328D LCR has been designed for use in specific applications that require high maneuverability in confined spaces, it still maintains the ability to accomplish tasks in a variety of applications where space is not a factor.

Swing Radius
The Cat 328D LCR has a tail swing radius of 1900 mm compared to 3090 mm for the standard Cat 329E L. This reduction of tail swing may allow for swing operation with greater confidence knowing that the tail of the machine only has a minimal amount of overhang.

Lift and Stability
The boom on the 328D LCR has been moved more toward the center of the machine. This results in overall greater lift capacity over the front as compared to the standard 329E L. In addition to the repositioning of the boom, the Cat 328D LCR utilizes the undercarriage of the 336D L, which allows for an extremely stable operating platform.

328D LCR versus 329E L
The tail swing radius for the 328D LCR is 1900 mm compared to 3090 mm for the 329E L. The 328D LCR's minimum front swing radius is 3412 mm and the 329E L's is 4180 mm.

C7 with ACERT Technology
Built for power, reliability, economy and low emissions.


C7 with ACERT Technology

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 EPA/ARB Flexibility requirements and EPA/ARB Tier 4 Interim AB&T requirements for emission regulation.

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

Automatic Engine Speed Control
The two-stage, one-touch 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 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 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 328D LCR side-by-side cooling allows easy access to keep the cooling cores free of debris.

Air Cleaner
The radial seal air filter features a double-layered core for more efficient filtration.

Noise Reduction Technologies
Engine mounts are rubber coated to reduce vibrations. Further noise reduction is achieved through design changes to the isolated top cover, oil pan, sculpted crankcase, and other components.

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


Hydraulics

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, reducing 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 boom-down and stick-in operation. This increases operator efficiency and 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, multi-processors, and vibratory plate compactors.

Hydraulic Cylinder Snubbers
Snubbers are located at the rod-end of the boom cylinders and both ends of the stick cylinders. Benefits include reducing sound levels and shocks while extending component life.

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