Product Details:
The CT12B4U/BU Mini Excavator redefines versatility in compact spaces with its lightweight yet robust design, engineered for urban construction, agriculture, and confined job sites. Equipped with dual-engine options (YANMAR 3TNV74F or 3TNV70), it delivers tailored power and fuel efficiency for diverse tasks.
The zero tail swing (550 mm radius) ensures safe operation near obstacles, while the advanced hydraulic system (17 MPa pressure, up to 19.2 L/min flow) enables rapid, precise digging and lifting. Tackle deep excavations (1,830 mm depth), high-reach tasks (3,062 mm height), and vertical wall challenges effortlessly with 10 kN bucket force. Featuring adjustable track width (850–1,100 mm) and 31 kPa ground pressure, it excels on slopes and sensitive terrain. Built for durability and operator comfort, its ergonomic cab and reinforced undercarriage make it ideal for landscaping, utility work, snow removal, and more—combining agility, power, and reliability in one compact powerhouse.
