The CAT 312d hydraulic excavator is designed to provide high performance and efficiency in light- to medium-duty applications. It is powered by a fuel-efficient Cat C4.2 engine with ACERT™ technologies, which not only ensures compliance with emission standards but also delivers exceptional power for increased productivity. The state-of-the-art hydraulic system of the 312d offers more hydraulic pressure for additional lift and breakout forces, while the boom and stick regeneration circuit saves energy and improves fuel efficiency. The machine is built with robust frames and components for durability and reinforced in high-stress areas to ensure reliability and longevity. Regular maintenance points are easily accessible, many at ground level, for efficient serviceability. The spacious and comfortable cab provides a quiet work environment with automatic climate control and adjustable seating for operator comfort. The 312d also comes with advanced technology options such as Cat Product Link for fleet management and AccuGrade™ for precise grading control.
