The Model-12 mini excavator features an ultra-compact and lightweight body, specially designed for ultra-narrow spaces and micro fine construction scenarios, serving as a lightweight and multi-functional engineering equipment. Equipped with an imported Kubota engine, it delivers stable and reliable power output with ultra-low fuel consumption, low operating noise and excellent energy-saving performance, supporting long-term continuous and stable operation. Fitted with a sensitive and accurate hydraulic system and a front dozer blade, the machine achieves smooth and flexible control with precise and coordinated movements, capable of completing integrated construction operations including digging, backfilling, site leveling and ground compaction. Adopting retractable flexible rubber tracks with shock absorption and anti-slip performance, it fits the ground perfectly without damaging asphalt roads, floor tiles, lawns and green vegetation. It can flexibly operate in narrow lanes, indoor spaces, greenhouses, orchards and community green belts, ideal for construction in confined sites. This excavator supports quick replacement of various attachments such as hydraulic breakers, auger drills, grapples and narrow buckets, efficiently completing various micro construction tasks including trenching, crushing, drilling, tree planting and pipeline laying. With a compact and lightweight structure, it is extremely convenient for transportation and can be easily loaded by ordinary light trucks without large transport equipment. Widely applied in courtyard renovation, fine garden maintenance, small-scale farmland planting, municipal micro maintenance, indoor demolition, rural path maintenance and small residential foundation construction, the Model-12 mini excavator is easy to operate, ultra-low in failure rate, highly durable and cost-effective. It is an ideal micro construction machine for individual contractors, agricultural and forestry operations, and small-scale fine construction projects.
