The Cat® 308 mini excavator is engineered to deliver superior performance while adhering to the strictest environmental standards. At its core, the Cat 308 is powered by the robust Cat® C3.3B engine, meticulously designed to meet U.S. EPA Tier 4 Final, EU Stage V, and Japan 2014 emission standards. This commitment to emission regulation ensures a reduced environmental footprint without compromising on power and operational excellence.
Engine and Fuel Efficiency
The Cat C3.3B engine stands out for its fuel efficiency and adaptability. It is compatible with a range of fuel types, offering operational flexibility. The engine is designed to run optimally on:
- Ultra-Low Sulfur Diesel (ULSD) fuel with 15 ppm of sulfur or less.
- ULSD blended with lower-carbon intensity fuels, including:
- Up to 20% biodiesel FAME (fatty acid methyl ester)*
- 100% renewable diesel, HVO (hydrotreated vegetable oil), and GTL (gas-to-liquid) fuels.
These fuel options empower operators to choose more sustainable fuel alternatives, contributing to reduced greenhouse gas emissions and aligning with global environmental initiatives. For detailed guidelines on fuel application, consulting with a Cat dealer or referring to the “Caterpillar Machine Fluids Recommendations” (SEBU6250) is advised.
To further enhance fuel conservation and reduce unnecessary engine operation, the Cat 308 incorporates several smart features:
- Auto Idle: This feature automatically transitions the engine to idle mode when the machine is inactive, significantly cutting down on unnecessary fuel consumption and greenhouse gas emissions.
- Engine Idle Shutdown Timer: After a pre-set period of idling, the engine automatically shuts down, further minimizing fuel waste, greenhouse gas emissions, and prolonged idle times.
- Cruise Control: Maintaining a constant speed across the job site is crucial for efficiency. The cruise control feature in the Cat 308 helps maintain uniform speed, optimizing fuel usage and lowering greenhouse gas emissions during operation.
Safety and Maintenance Advantages
Operator safety and ease of maintenance are paramount in the design of the Cat 308. It includes features that prioritize both:
- Cat Seat Belt Reminder: An audible and visual alert system reminds operators to fasten their seat belts, promoting safe operation across all equipment brands. This easy-to-install system underscores Caterpillar’s commitment to operator safety.
- Extended Maintenance Intervals: The Cat 308 is designed for extended maintenance intervals, which translates to reduced downtime and fewer replacements of fluids and filters over the machine’s lifespan. This not only saves time but also minimizes waste and reduces maintenance costs.
- Remote Flash (if equipped): Leveraging digital connectivity, Remote Flash technology minimizes downtime by enabling remote software updates. Alerts for machine updates are conveniently sent from the Cat dealer, and updates can be deployed without requiring an on-site technician. This ensures the Cat 308 operates at peak efficiency with the latest software enhancements.
- Remote Troubleshoot (if equipped): This feature allows Cat dealers to remotely diagnose and troubleshoot machine issues. By virtually testing the machine in operation, dealers can quickly pinpoint problems, often enabling technicians to resolve issues on the first visit, saving considerable time and maintenance expenses.
Advanced Grade Control Technology
For operations requiring precision grading, the Cat 308 can be equipped with integrated Cat Grade technologies:
- Cat Grade with Advanced 2D and 3D: These optional advanced grading systems combine sophisticated guidance with automated machine control. This technology assists operators in achieving grading targets more efficiently, enhancing job site productivity and accuracy while simultaneously reducing fuel burn and greenhouse gas emissions by optimizing machine utilization.
The Cat 308 mini excavator encapsulates a blend of powerful performance, fuel efficiency, safety features, and advanced technology, making it an ideal choice for demanding applications where precision and environmental responsibility are key.
*Engines without aftertreatment devices can accommodate higher biodiesel blends, up to 100%. For blends exceeding 20% biodiesel, consultation with a Cat dealer is recommended.
