CAT 308C Excavator is powered by a Cat C3.4B engine with a net power of 54.8 kw (74.5 hp). This engine delivers strong output power and torque, enabling the excavator to handle various complex operations with ease1. It meets the emissions standards set by the Environmental Protection Agency (EPA) and the European Union (EU), ensuring both high performance and environmental friendliness.



308C is equipped with a high – performance hydraulic system with load – sensing technology. This technology can match the hydraulic flow to the job requirements, providing smooth and precise control while ensuring efficient power transfer. The hydraulic system relief valve pressure is 3980 psi, which can meet the needs of different working conditions2.


308C CR model features a zero – tail – swing design, meaning that the tail of the machine remains within the width of its tracks. This is especially 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 limited areas.

308C is equipped with an advanced control system that is easy to operate1. The brake control is sensitive, providing a good control feel1. In addition, the excavator is equipped with a variety of safety features, including a rear – view camera, backup alarm, and emergency stop button, which help prevent accidents and ensure a safe working environment.


The Caterpillar 308C is made of high – strength materials and has been subjected to strict quality inspection and testing1. Its various components are easy to maintain and replace, which helps reduce maintenance costs and time, and improve the reliability and stability of the equipment1. The track – type undercarriage has a large contact area with the ground, low ground pressure, and good passability, which can adapt to various harsh working conditions.
