KAISAN New 1.2-Ton Crawler Mini Excavator: Zero Tail Design for Tight-Space Operations
KAISAN New 1.2-Ton Crawler Mini Excavator: Zero Tail Design for Tight-Space Operations
KAISAN, a leader in small construction machinery, officially releases its new 1.2-ton crawler mini excavator KN12-9. Built for municipal maintenance, garden care, courtyard/indoor renovation, this machine integrates four core strengths: Yanmar power, precise hydraulics, tail-swing-free flexibility, and easy maintenance—solving traditional small excavator pain points (space limits, high fuel use, tough maintenance) while boosting operator comfort.
Core Advantages: Performance & Practicality
1. Yanmar Power + Efficient Hydraulics
Equipped with a Yanmar 3TNV70 engine (10.3KW output), it delivers low noise (99dB), low fuel consumption (2.1L/h, 15% more efficient than peers), and stable performance (1,000-hour continuous operation test passed).
The hydraulic system combines Taifeng load-sensing valve, Tandem gear pump, and LKC two-speed piston travel motors—enabling delay-free composite actions (boom lifting + slewing), 20% faster response, and stable operation on muddy/narrow terrain (18kN traction for slopes, 4.2km/h travel speed for relocation).
2. Zero Tail Swing Design + Precise Control
Zero tail swing slewing (1.3m radius, Cast iron counterweight), it fits 1.5m-wide alleys and 3m-deep basements—avoiding collisions with walls/pipelines.
Hydraulic pilot control system (3.5N lever force) enables millimeter-level precision (e.g., 30cm×30cm tree pits, shallow trench excavation), reducing over-excavation waste.
3. Durable Protection + Easy Maintenance
Rear-mounted boom cylinder: Hides the cylinder to cut collision risks, lowering failure rate by 60%.
Concealed hydraulic pipelines: Prevents rain/dust erosion, extending hydraulic system life to 5,000+ hours.
Hatchback engine compartment: One-hand opening for 15-minute daily maintenance (oil change, air filter cleaning); quick-wear parts (travel wheels, bucket teeth) replaceable without full disassembly.
4. Ergonomic Design + Optional Functions
Premium ergonomic seat: 8cm high-density sponge, 3-stage shock absorption (filters 70% vibration) for long-hour comfort.
Optional features: Swing Boom (45° left/right swing for wall-side work) and Retractable Chassis (800mm-950mm width adjustment for narrow passages/stable slopes).
Proven in Real Scenarios
The excavator has been tested in municipal alley pipeline repair, garden tree pit digging, and underground garage construction—proving adaptability to tight spaces and light-duty tasks.
5. Compliance & Support
Certified with CE and ISO 9001; Emission standards: EU standard: Euro 5 Stage; USA standard: EPA Tier-4; Noise certification(99dB). Key components (engine, hydraulic valve) come with 12-month/1,000-hour warranty. KAISAN offers:
Free on-site training for operators/maintainers;
24-hour technical response and fast spare parts delivery;
Customized configurations (bucket types + optional functions) for specific scenarios.
