C7 with ACERT™ Technology Built for power reliability, economy and low emissions. 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.
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.
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 right-hand wall. The monitor is easy to see and maximizes visibility. Multi-information Display. This area is reserved for displaying various information which is convenient for the operator. The “CAT” logo is displayed when no information is available to be displayed. Standard Cab Equipment.
Structures 328D LCR structural components and undercarriage are the backbone of the machine’s durability. Robotic Welding. Up to 95% of the structural welds on a Caterpillar® Excavator are completed by robots. Robotic welds achieve over three times the penetration of manual welds. Carbody Design and Track Roller Frames. X-shaped, box-section carbody provides excellent resistance to torsional bending.
Booms, Sticks and Bucket Attachments Designed for maximum flexibility, productivity and high efficiency on all jobs, the 328D LCR offers a wide range of configurations suitable for a variety of applications. Reach Boom. The reach boom features an optimum design that maximizes digging envelopes with three stick choices: R3.2CB2 Stick. The CB-family buckets associated with these sticks have enough capacity for excellent reach and depth in trenching and general construction applications. R2.65CB2 Stick.
Work Tools – Attachments The 328D LCR has an extensive selection of work tools to optimize machine performance. Ditch Cleaning (DC) Buckets. These wide shallow buckets are best for bank forming, ditch cleaning, and finishing. Heavy Duty Buckets. Heavy-duty (HD) buckets are used for a wide range of moderately abrasive applications such as mixed dirt, clay and rock. HD buckets have best loading and dumping characteristics and will empty easier in cohesive material.
Versatility A wide variety of optional factory-installed attachments to enhance performance and improve job site management. Auxiliary Hydraulics Options. There are four different options that can be factory installed to meet the various demands for hydra-mechanical tools. • Single-Function • Double-Function • Tool Control System • Medium Pressure Single-Function Auxiliary Hydraulics. This single-function circuit utilizes one-way flow action with two pumps.
Service and Maintenance Simplified service and maintenance features save you time and money. Radiator Compartment. The left rear service door allows easy access to the engine radiator, oil cooler and air-to-airafter-cooler. A reserve tank and drain cock are attached to the radiator for simplified maintenance. Ground Level Service. The design and layout was made with the service technician in mind.
