CAT 309 CR

[Product Overview] The Caterpillar 309 CR is a 9-tonne class mini-excavator. It features a High-Flow hydraulic system—a rarity in compact machinery—combining the agility of a compact design with the high-performance capabilities of larger equipment. Its Compact Radius (CR) design makes it ideal for operations in confined spaces, such as urban construction, pipeline laying, and road maintenance. [Key Performance & Technical Advantages] 1. Superior Hydraulic Performance: Equipped with a High-Flow auxiliary hydraulic system, it easily powers heavy-duty attachments (such as high-output hydraulic hammers, planers, and mulchers), significantly expanding its operational versatility. 2. Powerful & Eco-friendly: Powered by the Cat C3.3B engine delivering 51.8 kW (69.5 HP), it meets strict Stage V / Tier 4 Final emission standards, offering robust power alongside fuel efficiency. 3. Compact Radius (CR) Design: With a minimal tail swing radius, operators can work close to walls or in narrow passages without worrying about tail collisions, enhancing both safety and efficiency. 4. Industry-Leading Operator Experience: - The cab features a sealed, pressurized system and high-efficiency air conditioning, ensuring a low-noise, low-dust environment. - Cat’s exclusive "Stick Steer" system allows for seamless switching from traditional pedal-based travel to joystick control with the push of a button, making operation easier. - A color LCD monitor provides intuitive machine status updates, personalized settings, and a secure passcode unlock function. 5. Easy Maintenance: Designed with large access doors on the chassis and machine sides, all daily inspection points (oil levels, filters, etc.) are easily accessible from ground level, drastically reducing downtime for maintenance. [Machine Condition] - Well-maintained; the hydraulic system is responsive with no leaks, and the engine runs smoothly. - Structural components are in excellent condition; the machine is ready for immediate deployment to the job site. On-site inspections and test drives—or video inspections—are welcome!
