Cat 374F Meets US EPA Tier 4 Final and EU Stage IV Emission Standards, Delivers High Fuel Efficiency, and Provides Optimum Operator Comfort

For Release in Australia & New Zealand: July 2016
Release Number: 234PR16

The new Cat® 374F hydraulic excavator, replacing its D-Series predecessor, uses a fuel-efficient Cat C15 ACERT™ engine that meets Tier 4 Final and Stage IV emission standards. The new model, building on the durability, reliability, and performance of the D-Series, reflects the Caterpillar F-Series design criteria, including low fluid consumption for minimal operating costs, optimum operator comfort, easy serviceability, and high productivity. With a maximum operating weight of 74,960 kg, the 374F features heavy-duty main structures, a choice of front linkages, a wide selection of work tools for optimum versatility, and available grade-control and telematics systems.

Engine/hydraulics

With a net power rating of 352 kW (ISO 9249), the C15 ACERT engine uses a combination of proven emissions-control technologies, including electronic management of fuel-injection/intake-air systems and Caterpillar designed exhaust after-treatment systems. Emissions control is transparent to the operator and does not affect machine performance. Compared with Stage IIIB predecessor engines, the 374F’s C15 ACERT engine delivers greater fuel efficiency (more material moved per unit of fuel)—based on lower fuel consumption (up to 10 percent less, depending on application).

Two power modes—standard or economy—allow the operator to select an engine operating speed to match the application, resulting in further fuel savings. In addition, an on-demand-power system adjusts engine speed to match the machine's operating load, and an engine-idle-shutdown system stops the engine after a preset idling interval. These systems not only save fuel and reduce emissions, but also significantly extend service intervals.

The 374F implement hydraulic system is designed with major components in close proximity, an arrangement that allows shorter connecting tubes and hoses to reduce frictional losses and pressure reductions, resulting in reduced loading on the system for added fuel savings. New for the F-Series model is the Cat Adaptive Control System valve, which electronically manages flows and restrictions to exactly match hydraulic response to joystick movement. This fuel-saving feature also promotes smooth operation of hydraulic functions and adds to overall hydraulic efficiency.

The new model can be equipped with auxiliary-hydraulic circuits, allowing the use of powered work tools that can be easily attached with a hydraulically activated coupler. For further fuel savings, electrically controlled regeneration systems in the boom and stick circuits move oil between the cylinder ends to reduce the load on the main hydraulic pumps.

Structural strength

The 374F is available with a range of booms and sticks fabricated with heavy, premium-steel plate and using high-strength castings and forgings in high-stress areas. All are stress-relieved for durability and inspected ultrasonically for quality. A heavy-duty reach boom and general- purpose boom are designed for general excavating and loading, and a mass-excavation boom delivers high production in large-scale earthmoving and heavy-material applications. A choice of sticks is available to match booms for required digging depth, reach and breakout force.

Structural durability is ensured by the proven heavy-duty construction of the mainframes and undercarriage, with the upper frame incorporating special mountings to support the heavy-duty cab, and the lower frame heavily reinforced for long-term durability. A long-track, variable-gauge undercarriage—featuring massive track roller frames and high-tensile-strength-steel components—provides a wide, stable working base, while adjusting to reduce shipping width. A new counterweight removal device is available to allow easier and more cost-efficient transport.

Cab/serviceability/technology

Increased glass area (12 percent more) in the F-Series cab enhances visibility for the operator, and the in-cab sound level is reduced by a significant 3 dB(A). The new LCD monitor offers a large screen, high resolution, and provides intuitive navigation. The monitor is programmable in 42 languages, presents detailed machine operating data, and displays images from the standard rearview camera. The 374F cab uses special sealing and insulation to keep the operator's environment clean and comfortable. A climate-control system includes air conditioning and filtered-air ventilation; seat options include air-suspension, heated, and cooled versions.

Routine maintenance points—grease fittings, fuel and oil filters, fluid taps—are conveniently grouped on the F-Series and are safely reached behind large service doors accessed from wide, slip-resistant catwalks. A fuel-tank drain cock simplifies evacuating water and sediment, and an integrated fuel-level indicator reduces the prospect of overfilling.

Cat Connect makes use of technology and services that help improve jobsite efficiency. LINK technologies, such as the available Product Link™ system, help owners manage equipment productively and reduce overall owning and operating costs via the online VisionLink® interface.  VisionLink allows tracking critical data, such as location, hours, fuel usage, diagnostic codes, and idle time. F-Series machines also offer optional GRADE technologies, such as Cat Grade Control Depth and Slope to help operators work more productively and accurately. These systems can be upgraded to 3D capability when job requirements change.
