328D LCR^Non-Current

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.

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.

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.
