The CAT 308C Excavator is powered by a Cat C3.4B engine, delivering a net power of 54.8 kW (74.5 hp). This engine provides strong output power and torque, allowing the excavator to handle a wide range of complex operations with ease. It meets the stringent emissions standards set by the Environmental Protection Agency (EPA) and the European Union (EU), ensuring both high performance and environmental compliance.



The CAT 308C Excavator is equipped with a high-performance hydraulic system featuring load-sensing technology. This technology ensures that the hydraulic flow is matched to the job requirements, providing smooth and precise control while ensuring efficient power transfer. The hydraulic system’s relief valve pressure is 3980 psi, making it capable of handling a variety of working conditions with ease.


The CAT 308C CR model features a zero-tail-swing design, which means the rear of the machine stays within the width of its tracks. This is particularly advantageous when working in tight spaces or urban environments, as it reduces the risk of collisions with surrounding objects and allows for more efficient operation in confined areas. This design makes it ideal for jobs where space is limited and maneuverability is crucial.

The CAT 308C is equipped with an advanced control system that is user-friendly and easy to operate. The brake control is highly responsive, providing a good control feel for the operator. Additionally, the excavator comes with a variety of safety features, such as a rear-view camera, backup alarm, and emergency stop button. These features help prevent accidents and ensure a safe working environment, making the 308C a reliable and secure choice for various job sites.


The Caterpillar 308C is constructed from high-strength materials and undergoes strict quality inspection and testing. Its components are designed to be easy to maintain and replace, which helps reduce maintenance costs and downtime, while improving the overall reliability and stability of the equipment. The track-type undercarriage has a large ground contact area and low ground pressure, providing excellent passability. This makes it well-suited for various harsh working conditions, ensuring that the 308C can operate effectively in challenging environments.
