Product Details:
The CT12B4U/BU Mini Excavator revolutionizes compact-space operations with the mini excavator’s lightweight, durable design, perfectly suited for urban construction, agriculture, and tight job sites. Boasting dual-engine choices of YANMAR 3TNV74F or 3TNV70, the mini excavator offers customized power and optimal fuel efficiency for any task.
The mini excavator’s zero tail swing design, with a mere 550 mm radius, guarantees safe operation around obstacles. Coupled with an advanced hydraulic system delivering 17 MPa pressure and up to 19.2 L/min flow, the mini excavator enables swift and precise digging and lifting. With a formidable 10 kN bucket force, the mini excavator effortlessly handles deep excavations reaching 1,830 mm, high-reach tasks up to 3,062 mm, and vertical wall challenges.
The adjustable track width of the mini excavator, ranging from 850–1,100 mm, along with 31 kPa ground pressure, allows the mini excavator to perform exceptionally well on slopes and delicate terrains. Engineered for longevity and operator comfort, the mini excavator’s ergonomic cab and reinforced undercarriage make the mini excavator a versatile choice for landscaping, utility work, snow removal, and more. This mini excavator packs agility, power, and reliability into one compact yet mighty machine.
